FREQUENTLY ASKED QUESTIONS (FAQ) ON LSZH CABLES

---

What does LSZH mean in cables?

It refers to a type of cable that is designed to emit very little smoke and no halogen gases when it burns. This makes LSZH (also referred to as LSHF or LSOH) cables a safer option for use in enclosed spaces, as they reduce the risk of toxic fumes and improve visibility during a fire.

---

What to consider when purchasing cables for a building / industry/ project?

Choosing the right cable is essential to ensure the safety of people and efficiency of the electrical system. In terms of fire safety, it is vital to check:

The cable’s reaction to fire. How quickly the cables spread flames and therefore how long they allow for successful evacuations, and how much smoke or other dangerous gas is released.

The cable’s resistance to fire. How long they can maintain the integrity of a circuit and stay functional for the use of the emergency services and other fire-fighting installations.

---

Why consider Halogen-Free LSZH cables and where can it be used?

LSZH (low-smoke halogen-free) cables are used in installations when fire safety, fire damage prevention may become a concern, such as large affluence of public locations.

---

When is it mandatory to use halogen-free cables?

Low Smoke Zero Halogen cables are highly recommended (and mandatory in certain countries) in all premises open to the public such as: airports, arenas, concert halls, department stores, offices, hotels, etc.

---

What are halogens?

Halogens are non-metallic elements found in the periodic table. The five halogens are fluorine, chlorine, bromine, iodine, and astatine. They are present in PVC insulation and jacketing, and are highly flame retardant. However, when they are burned, halogens emit thick toxic smoke and become corrosive which can cause damage to equipment and pose a safety concern.

---

What are the benefits of a LSZH cable?

Halogen free cables with reduced smoke production save lifes in the event of a fire:

• Provide a smoke-free escape route.
• Protect the structure of the building.
• Limit the smoke damages to equipment.
• The smoke is less hot and non-corrosive.
• Facilitate the work of firefighters in the building.

---

How can you tell if a cable is halogen-free?

You can tell if a cable is low-smoke halogen-free by looking for specific markings or labels on the cable itself or its packaging.

---

Are LSZH cables more environmentally friendly?

LSZH cables are generally considered more environmentally friendly compared to traditional cables that contain halogens. This is because LSZH cables do not release toxic gases when burned (such as smoke and harmful effluents), which can be harmful to both human health and the environment.

Additionally, they are often made with materials that are less harmful to the ecosystem, so when they reach the end of their lifespan, they can be disposed of using simpler, cheaper and cleaner treatments than standard cables.

---

Are Low-Smoke Halogen-Free Cables allowed in all applications?

Low Smoke halogen-free (LSZH) cables are intended for use in applications in which cables with low toxicity, low smoke generation, and low corrosiveness are needed. Examples include public places such as rapid transit, industrial, shipboard, aerospace, and commercial applications where human safety and protection of equipment is a concern.

---

Is there a difference between low-smoke and zero-halogen?

Low smoke cable emits a thinner and clearer smoke when burning, making possible evacuation and firefighting efforts easier and safer. A cable may be low smoke and still contain toxic halogens.
Zero halogen means that the cable does not contain fluorine, chlorine, bromine, iodine, or astatine. Zero halogen cable may still emit thick smoke when burned. Both properties are not always needed for all cables. Check specifications to be sure that the cable meets both requirements if necessary for your application.

---

Which installations recommend the use of LSZH cables?

Low-Smoke Halogen-Free (LSZH) cables have been designed to provide maximum protection to people and equipment in the event of fire. They are specially recommended for:

• Hospitals.
• Offices, universities, schools.
• Malls, supermarkets, shops in general, museums.
• Trains.
• Ships, Submarines.
• Railway, road, & tunnel systems.
• Nuclear power stations, and much more.

---

Where do I have to install LSZH?

LSZH (Low Smoke Halogen Free) are power cables for public places such as: hospitals, schools, museums, airports, bus terminals, shopping malls, offices, laboratories, etc. In the event of fire, these cables do not spread fire nor emit toxic or corrosives gases, preventing any possible harm to people or electronic equipment. In Europe, fire performance is regulated by the European CPR (Construction Products Regulation).

---

What are LSZH (Low smoke zero halogen cables) and where are they mainly installed?

In the event of a fire, LSZH cables do not spread flames and therefore allow for successful evacuations, not emitting smoke or releasing toxic gasses. This facilitates the evacuation of people and the work of rescue personnel. Therefore Low smoke halogen free LSZH cables are highly recommended for installation in all premises open to the public such as: airports, arenas, concert halls, department stores, offices, hotels.

---

---

What does CPR B2_ca s1a, d1, a1 mean? What does CPR C_ca s1b d1 a1 mean? What is CPR (Construction Products Regulation) in a cable?

The CPR classification of TOP CABLE TOXFREE® RZ1-K cable is B2_ca-s1a,d1,a1 / C_ca-s1a,d1,a1. In several European countries, the installation of CPR C_ca-s1a,d1,a1 cables is mandatory in public places such as: hospitals, schools, museums, airports, bus stations and shops in general.

Here you can read more about the European Construction Products Regulation and its fire performance classification system for electrical cables.

---

What is the purpose of the CPR (Construction Products Regulation)?

The European Construction Product Regulation (CPR) provides a “common technical language” to assess the performance of Construction products in the event of a fire, and to compare the performance of products from different manufacturers in different countries.

These methods are compiled in harmonised standards or technical specifications. This common technical language is to be applied by:

• Manufacturers when declaring the performance of their products (DoP)
• Authorities of Member States, specifying requirements.
• Users (architects, engineers, constructors, distributors…) when choosing the products most suitable for their intended use in construction works.

Further information can be found here.

---

What benefits does CPR (Construction Products Regulation) generate for Europe?

CPR generates a higher level of safety for all European citizens because:

• Same level of safety for all end-users. National requirements are regulated and not just recommended.
• Safer solution for critical applications. National Regulators can rely on a sophisticated classification of performances to regulate the level of performance.
• Withdrawal of unsafe cables. Once a non-compliance is detected, National Authorities can impose the withdrawal of unsafe cables from the market.

Users of construction products can better define their performance demands because:

• The manufacturer takes full responsibility of the performance in the Declaration of Performance, which is a legally binding document -8the consequence of non-conformity for the manufacturer can be devastating).
• The product’s assessment and constancy assessment are defined by the Assessment and Verification of Constancy of Performance procedures and carried out by third parties.
• Market surveillance is more efficient because you rely on one common information structure and on dedicated resources.

---

What is the added value of CPR?

The Class of Reaction-to-Fire table will become a standard of building regulations in Europe, though they are likely to be applied differently across the EU. Indeed, each country, under the principle of subsidiarity, will decide how these classes are to be used in its construction standards and/or regulations.

These Classes will, however, certainly become a point of reference as, whatever their application, they will be common to all products. The performance level of the products defined by the classes will be clearly understood by all European decision-makers. The products brought to market will comply with strenuous testing requirements, and continue to ensure that the safety of persons, animals and goods in fire hazards can be protected.

---

Are smoke emission and toxic gases emission covered by the CPR?

Yes. Only for B2ca and Cca cables:

• s (“smoke”): Smoke production, with possible levels s1, s1a, s1b, s2 and s3.
• d (“droplets”): Flaming droplets/particles, possible levels being d0, d1 and d2.
• a (“acidity”): Acidity and conductivity, with possible levels a1, a2 and a3.

---

To which products does the CPR apply?

The CPR applies to all construction products that are permanently incorporated into buildings or civil engineering works. Cables are included into the CPR: not only power cables but also control cables, communication and fibre optic cables are covered by the CPR when permanently installed in a construction work.

---

What performances of cables are covered by the CPR (Construction Products Regulation)?

The harmonised standard for cables EN50575:2014/A1:2016 only specifies requirements for the fire reaction of cables. Cables are classified into fire classes, according their fire performance: B2_ca, C_ca, D_ca, E_ca.

Class B2_ca offers the best fire performance and E_ca the lowest fire performance, meeting the minimum requirements.

---

Which cables are included under the CPR (Construction Products Regulation)?

Cables for permanent installation in constructions within the scope of the two harmonised product standards:

• Cables intended to be used for the supply of electricity and communications in buildings and other civil engineering works and subject to performance requirements on reaction to fire.
• Cables intended to be used for the supply of electricity, communication and fire detection and alarm in buildings and other civil engineering works where it is essential to assure the continuity of power and/or signal supply of safety installations.

Cables for permanent installation are considered those which are not specifically designed for temporary installation only. Those that are not considered lift cables or other cables specifically designed for use in industrial processes carried out in industrial premises that are not part of the Mandate M/443 EU.

---

What is the difference between C_ca and B2_ca?

According to European Construction Product Regulation (CPR) , there are seven Euroclasses that apply to cables: B2ca, Cca, Dca, Eca and Fca, with B2ca having the highest fire performance and Fca having the lowest protection in the event of a fire. Watch this informative video.

---

Do cables in prefilled conduits and pre-connected systems have to be CE marked?

It is important that any cables used in prefilled conduits and pre-connected systems comply:

• If the prefilled conduits’ and pre-connected systems’ final application is in construction and civil engineering works subject to reaction to fire requirements, or
• If they are sold through the distribution channel and their final application can be construction and civil engineering works subject to reaction to fire requirements.

---

Are Fire Resistant cables covered by CPR (Construction Products Regulation)?

CPR (Construction Products Regulation) covers both reaction to fire and resistance to fire performances, but so far only the harmonized standard EN 50575 for reaction to fire is available. Therefore, fire resistant performance cannot be certified under the CPR Individual member states may adopt and apply their own local requirements for the fire properties of fire resistant cables.

---

Which additional burdens are imposed by the CPR (Construction Products Regulation) on the industry?

• An additional testing/certification procedure to current Quality Marks. The severity of this burden is growing with the level of performances declared. Tests are more sophisticated moving up from Class Eca to Dca and upper (from small size flame test to full size fire scenario) and routines of continuous surveillance to certify the conformity to the DoP of the full production of Class Cca and B2ca cables under System 1+ is particularly strict and costly. The CPR implementation impacts many company functions: technical, manufacturing, logistics, quality management and IT.
• The new marking, labelling and electronic distribution of the DoPs required a huge investment to warrant the perfect alignment of all these new documents and texts and to warrant the full availability for end-users. In many cases it obliges them to add new labels on products. DoPs have to be maintained and available for 10 years after stopping production.
• Most of cables of Classes Dca and above required a full redesign to warrant the conformity of all types to the DoP. New materials have been developed on purpose to fulfil the new Euroclasses and the additional requirements like flaming droplets.
• For all cables of every level of performance much severe consequences in case of non-conformity up to the total withdrawal of the product from the market.

---

What will be common in Europe and what specific by country in the application of the CPR (Construction Products Regulation)?

The CPR should be applied without differences of interpretation by each Member State. The Classification is the common language to define the level of fire performances of cables (Reaction to Fire at the moment) and to be used in local Regulations and in Users requirements.

Any decision on which Class to adopt for a particular application is a National matter and could vary between different Member States. The wide range of combinations of the parameters (Class + smoke + acidity + droplets) gives the Member States a great flexibility.

Not every Member State regulates the fire performances of cables.

---

What are the obligations of the manufacturer under the CPR (Construction Products Regulation)?

The obligations are set out in Art.11 of the CPR as follows.

When a product is covered by a harmonised standard, the manufacturer shall draw up and keep for 10 years the Declaration of Performance (DoP) and affix the CE marking.

Manufacturers shall ensure that series production maintains the declared performance. That their products bear their registered trade mark and contact address and elements allowing their identification and instructions and safety information.

Manufacturers who consider that a product, which they have placed on the market, is not in conformity with the Declaration of Performance, shall immediately take the necessary corrective measures to bring that construction product into conformity, or, if appropriate, withdraw or recall it.

---

What is a Declaration of Performance (DoP)?

The DoP is a document drawn up for every product covered by the CPR by the manufacturer following regulatory guidelines which:

• Identifies the product and the manufacturer.
• Its intended use.
• Its essential characteristics as given by its harmonised Product Standard.

Further information on the Delegated Act No 574/2014 of 21 February 2014 on the model to be used for drawing up a declaration of performance on construction products, can be found here.

---

What is the purpose of the DoP (Declaration of Performance)?

The manufacturer, by drawing up his DoP, assumes the responsibility for the conformity of the construction product with the declared performance.

Based on the information contained in the DoP, the User, under its own responsibility, decides to purchase the product, which is fit for its application.

---

Is CE marking more or less important compared with my national quality mark?

CE-marking will be a pre-condition to place cable for construction works on the market. The relevance of the CE marking under the CPR (Construction Products Regulation) is the elimination of technical barriers among the Member States arising from the definition of fire performances as well as the uniform modality to attest the conformity of cables.

Quality Marks cover other aspects of the product such as mechanical and electrical performances and dimensions and are unique tools to monitor the compliance with voluntary standards. Therefore, a comparison between the CE marking and voluntary National Quality Marks is misleading because they are complementary.

---

How do CPR (Construction Products Regulation) requirements affect cable imported from outside the EU?

The CPR (Construction Products Regulation) requirements will apply to all cables placed on the market in the EU independently from the country of production.

---

How can the User know that a product is correct for applications under the CPR (Construction Products Regulation)?

The following elements are necessary for the user:

• Knowledge on the Euroclass requested by any national regulations for the defined building/construction works.
• Label which shows the CE marking with accompanying information related to the certification.
• Declaration of Performance from the supplier.

---

What are the differences between flame retardant and flame resistant cables?

Flame retardant cables have self-extinguishing properties and are difficult to burn. They can prevent the fire from spreading, preserving other equipment and preventing further damage.
Fire-resistant cables are cables that can be kept in operation for a certain period of time in the event of a fire.. They are often used in emergency power circuits to ensure the normal operation of circuits in the event of a fire.
Fire resistant cables are much safer. Usually, fire resistant cables can replace flame retardant cables, but flame retardant cables cannot replace fire resistant cables.

---
