Introduction of JC 692-1998

Fiberglass reinforced plastics pressure shells intended to be used in reverse osmosis water treatment unit 1 Scope This standard specifies the classification, labeling, raw materials, technical requirements, test methods and inspection rules of fiberglass reinforced plastics (hereinafter referred to as FRP) pressure shells intended to be used in reverse osmosis water treatment unit. It is applicable to FRP pressure shells intended to be used in reverse osmosis water treatment unit made by wound process by taking fiberglass and its products as reinforced material and epoxy resin as base. Its long-term service temperature ranges from -10℃ to +50℃. 2 Normative references The following standards contain provisions which, through reference in this standard, constitute provisions of this standard.
