Jan 09, 2017



PRE-TREATMENT



ISO   6330 ISO 15797

Before   each test, the test materials shall be washed and dried 5 times in accordance   with the procedure EN ISO 6330. If industrial washing and/or finishing is   allowed, then the protective clothing shall be washed five times in   accordance with ISO 15797.



PRESTACIONES TÉRMICAS



ISO   17493

Heat resistance at a  temperature   of 180ºC: All fabrics and hardware used in the   garment and/or clothing assembly shall not ignite or melt and shall not   shrink more than 5%

Heat resistance at a temperature of  260ºC: if the fabric shall be worn next to the skin, that material shall not   ignite or melt and shall not shrink more than 10%



ISO   15025

 

Limited flame spread The materials and seams, shall be tested   according to the procedure A  (A1 code) or procedure B (A2 code). When   tested according to the procedure A, shall meet the following requirements:

          a)    No   specimen shall give hole   formation.                                                             

         b)    No   specimen shall give flaming to the top or either side edge

         c)     No   specimen shall melt or give flaming or molten debris   

         d)    The   mean value of after-flame time shall be ≤ 2 s. 

         e)    The   mean value of after-glow time shall be ≤ 2 s.

         g)    Seams   shall continue to hold the panels of fabrics together

 When tested   according to the procedure B, shall meet the following   requirements:                                          

         a)    No   specimen shall give flaming to the top or either side edge

         b)     No   specimen shall melt or give flaming or molten debris   

         c)    The   mean value of after-flame time shall be ≤ 2 s. 

         d)    The   mean value of after-glow time shall be ≤ 2 s.
