GB/T 2910.15-2009 English PDF (GBT2910.15-2009)

This Part of GB/T 2910 specifies the method for determining the content of each component in a binary mixture of jute and certain animal fibers, by the nitrogen content method after removal of non-fibrous substances. Among them, the animal fiber can be a kind of wool or other animal fibers, OR the mixture of both. This Part does not apply to blended products containing nitrogen in dyes or finishes. Note: Since the principle of this method is different from the principle of selective dissolution in other parts, the format is different from other parts of GB/T 2910.
