PIA PIA-TEST METHOD-2611C PDF

This method is intended for determining, in cotton or cellulosic mixture yarns or cloths, the amount of sizing, finishing, and other nonfibrous materials, such as oils, fats, waxes, minerals, and other materials which will be removed or determined by chloroform and/or water extraction, hydrolized by enzyme action, or remain as inorganic material after exposure to high temperatures. Although this method is intended for the determination of nonfibrous materials in cellulosic textiles, it may be used for determining the extractable and nonfibrous materials content of certain noncellulosic textiles, as specified in the applicable end item specification or procurement document.

This method is not applicable to the determination of the amount of permanent types of finishes, such as urea condensates, melamine condensates, and substantive or organic finished, or to finishes that are volatile at 230°F (110°C).
