Step: 1- Precaution /Condition Taking before testing
S Receiving samples are required minimum 6 hours condition with temperature @ 20±2 °C & humidity 65±2 °C
Step: 3-For this test use of chemical(1):-10gpl ECE Non-phosphate reference detergent (A)(without optical brightener ),
(2)12gpl Sodium Perborate tetra hydrate (NaBo34H2O)
(3)1.8gpl TADE(Tetra-Acetyle Ethylene Diamine)with 100% activity
Note:-THE SOLUTION MUST BE FRESHLY PREPARE IMMIDIATELY PRIOR TO USE BECAUSE THE PERBORATE DEGRADE S WHEN WET
Step:4- Then cut the sample size of 10cmX4cm , No need to use any type of multifibre or steel ball for that test
Step:5-Take the sample and solution ratio 1:100ml
Step:6-Heat the waterbath and container to 270C±20C
Step:7-Weight the specimen and calculate the volume of wash liquor required to give a 100:1liquor ratio
Step;8-Place the specimen in the cointaner with the wash liquor
Step:9-Run the m/c and raise the temperature at arate of 1.50±0.50C per minute When temperature is reached began timing the test for 30minute
RINSING
Step:5-Light and dark colour must be rinsed separately
Step:6-Fill the 1 of the 2 lit beaker with cold distilled water and the 2nd beaker with cold tap water
Place the composite specimens in to the beaker with distilled water and stire/agitate the water for for 1minute Transhfer the sample into the 2nd beaker containing cold tap water and stir /agitate for 1minute
