4、JAPANESE INDUSTRIAL STANDARD J I S Glassfiber Reinforced Plastic Water Tanks A 4110-1989 1. Scope . This Japanese Industrial Standard specifies the integrated type water tanks, hereafter referred to as the “water tanks“, made- of glassfiber reinforced polyester of 50 m3 or under in capacity to be us
