What is the process of en 1101 flammability test for curtains?

according to EN 1101 The program , Before the test, it is necessary to confirm whether the curtain needs to be washed .

If the curtain doesn't need cleaning , Can be tested as is .

If you need to wash , Samples should be submitted to the cleaning procedure on the care label . If no cleaning procedure is specified , You need to choose one of the following ways to wash ：

• according to EN 26330 Methods 6A(40±3)℃ Washing and methods C dry
• according to ISO 3175 Dry and wash

Pretreatment conditions ：

Before testing , The sample shall be tested at the temperature of 23±2℃ And relative humidity 65±5% Standing at least 24h.

Sample specification ：

Each direction shall be provided with 12 A dimension for （200±2）mm×（80±2）mm Sample of .

Testing process ：

1. Place the specimen on the fixing pin of the specimen frame , Make the specimen vertical .
2. The igniter is placed under the front of the sample , Located in a plane perpendicular to the surface of the specimen through the vertical centerline of the specimen , Its longitudinal axis is in line with the vertical line 30°, Perpendicular to the bottom edge of the specimen . Ensure that the distance from the top of the igniter to the bottom of the sample is (20±1)mm.
3. Put the igniter in the vertical preparatory position , Ignite the igniter and preheat at least 2min. Adjust the vertical flame height under the black background so that the distance from the top of the igniter to the tip of the yellow flame is (40±2)mm.
4. Apply flame to the specimen , The flame application time is about the shortest time for sample ignition . Record the application time and whether the sample ignites .
5. Take samples from the same direction for testing . The time of flame application depends on the last test sample . If the previous sample has been ignited , Flame application time decreases 1s. Otherwise, the flame application time will be increased 1s. Record the application time and whether the sample ignites .

If the sample is in 1s Is ignited during the firing time , Retest , Remember not to ignite as “0”. If the sample is in 20s Has not been ignited during the firing time , Retest .

1. Repeat the first 5 Step test , Until at least 5 Specimens were ignited and 5 Specimens were not ignited .

If the sample is in 1s Is ignited during the firing time , Retest , Until there is 5 The same situation . If the sample is in 20s Has not been ignited during the firing time , Retest , Until there is 5 The same situation .
