Ask The ExpertHI what are normal stansard for Saliva test .
AnswerHi, Sorry I don't have an up to date refence number for this standard. I believe it was a German DIN Standard and some retailers have adopted it as an In house method. I would suggest that you contact the Society of Dyers and Colourists who look after the Colourfastness Standards for BSI who should be able to help you further. Sylvia Category |
