Wire and cable CE certification under the CPR cable EN50575 reference EN61034-2 standard for cable transmittance / smoke density test. EN50575 standard requirements of EN61034-2 cable transmittance at least up to 60%. Tel: 025-8658 3475.
 
EN50575 / EN61034-2 standard 
EN 61034-2 Measurement of smoke density of cables burning under defined conditions - Part 2: Test procedure and requirements. The measurement of smoke density is an important aspect of the evaluation of the combustion performance of the cable, because it relates to the difficulty of personnel escape.

Test method for smoke density of EN61034-2 wire and cable
In a furnace with a capacity of 27m3, as well as metering, ignition and other equipment. Cable requirements are flat, before the test in the temperature of 23±5 degrees in the pre placed for 16 hours. The test time is 40 minutes, and the smoke density test is expressed by the lowest light transmittance.
