LSHF SAFETY CABLES

Halogen-free, low smoke and low corrosive gases emission in case of a fire.

In compliance with Construction Products Regulation (CPR).

Top Cable, a global supplier to the world’s halogen free cables industry.

 

Halogen free cables, are highly recommended for installation in areas of high public traffic. We are referring, for example, to hospitals, airports, tunnels, subways, museums, as well as in offices, production plants, laboratories, etc. In this case, these cables have been designed to offer maximum protection to people in the event of fire. They do not spread fire (preventing it from reaching a new area), but also do not emit toxic or corrosive substances and have low smoke emissions. This facilitates the evacuation of people and the work of rescue personnel.

 

FREQUENTLY ASKED QUESTIONS (FAQ) ON LSHF CABLES


What is the purpose of the CPR?

The Construction Product Regulation (CPR) lays down harmonized conditions for the marketing of construction products in the EU. This is achieved by providing a “common technical language” offering uniform methods to assess the performance of construction products 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:

  • The manufacturers when declaring the performance of their products, but also by
  • The authorities of Member States when specifying requirements for them, and by
  • Their users (architects, engineers, constructors…) when choosing the products most suitable for their intended use in construction works.

Further information can be found here.


What benefits does CPR 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.

Fire performances are already available. Which added value the CPR and new rules and regulations are contributing?

The Class of Reaction-to-Fire Table considers the entire behaviour of cables in fire, dynamically measured against time on real sized samples. This is an important step forward in fire safety and allows National Authorities to treat cables in a similar manner to other construction products already covered by the CPR.

The Class of Reaction-to-Fire table will become a standard feature 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. It should be noted that it is not mandatory for classification to be introduced into National regulations and some countries may take the decision to address this issue in other ways.

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.


What performances of cables are covered by the CPR?

The performances of cables included under the CPR are:

  • Reaction to fire.
  • Resistance to fire (under consideration).
  • Release of dangerous substances in normal operation (not including performances during fire), dismantling and recycling.

Which cables are included under the CPR?

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.


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?

CPR 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 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?

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?

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.

See Chapter D.DECLARATION OF PERFORMANCES.
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?

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 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 requirements affect cable imported from outside the EU?

The CPR 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?

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.
