GB/T 5009.98-2003 Method for analysis of hygienic standard of unsaturated polyester resin and glass fibre reinforced plastics used as food containers and packaging materials (English Version)
This standard specifies the analytical method for the hygienic standards of unsaturated polyester resin for food packaging and its glass fiber reinforced plastic products. This standard applies to polyesters produced mainly from polyols, unsaturated dicarboxylic acid anhydrides, saturated dicarboxylic anhydrides, etc., and then adding styrene to obtain liquid unsaturated polyester resins, and the Analysis of various hygienic indicators of FRP products.
