LSZH Cable

The LSZH or Low Smoke Zero Halogen defines cable jacket materials featuring fire-retardant and non-halogenated properties. It produces decreased smoke levels and toxic fumes without acid gases. Since LSZH is non-halogenated, these cables are free from Chlorine, Astatine, Fluorine, and Iodine. These mentioned elements are all capable of being toxic and corrosive when combustion occurs.

Standards of LSZH Cable

There isn’t a universal definition or standard when it comes to LSZH cables.

However, most international standardization bodies have tests and standards that cable manufacturers must comply with in order to certify their cables as LSZH.

Manufacturers must test the cables according to the tests described by these standards.

For instance, the standard BS 61032 prescribes a test for smoke density.

The test is performed in a 3 x 3 x 3 cubic meter chamber.

A white light is passed through the chamber at a particular height to measure how the smoke hinders the transmittance of light.

The test requires the minimum transmittance to be 60 percent.

Similarly, another British cable standard, BS EN 60754, requires HCl emissions from the cable to be under 0.5 percent for it to qualify as zero-halogen.

The International Electrotechnical Commission (IEC) has its own set of standards and tests for qualifying cables as LSZH.

Here are the three most frequently used standards in the cabling industry:

IEC 60332-1 (Flammability)
IEC 61034-2 (Smoke emission)
IEC 60754-1 and IEC 60754-2 (Acid gas emissions)

The IEC 60332-1 test for flammability is similar to that of BS 61032, which involves a 3 cubic meter chamber and light transmittance.

The IEC 60754-1 test involves burning the cable for 60 minutes and collecting any halogen acid produced.

It should not exceed 5 mg/g.

The second part, IEC 60754-2, measures conductivity and pH.

The pH value should not be less than 4.3, and the conductivity value should not exceed 10 µS/mm.

LSZH cables also comply with the European Union (EU) Restriction of Hazardous Substances (RoHS) directive.

Other standardization bodies around the world may have similar tests for cables to qualify as LSZH.

The cables are not officially LSZH unless they meet the standards set by one of these bodies.
