Мф – actual weight of felt articles (circles, felt) in kg.
Wh – standard moisture of felt articles in % (in line with RST of the RSFSR 756-89 Wh = 13%)
Wф – actual moisture of felt articles in % (determined through laboratory analysis in the course of output handover from the place of production to the warehouse of the producer and put on the label glued to the article).
