Product Details：

RT-813D Fabric Flame Retardant Performance Tester (large 45°)

Scope of application:

Used to ignite fabrics in a 45 ° direction, measure their ignition time, smoldering time, damage length, damage area, or determine the number of times the fabric needs to come into contact with flames to burn to a specified length.

Meet standards:

GB/T14645-2014 Textiles―Burning behaviour―The 45°test determination of damaged area and ignition times

Method A is used to determine the damaged area and length of textiles and other materials when burned at 45 ° C;

Method B is used to determine the number of times textiles come into contact with flames when heated and melted to a specified length at 45 ° C.
