HAR 6-77-88 Plastic pipe
adhesive, or heat fusion may not be disturbed until it has properly set. Plastic pipe may not be joined by a threaded joint or miter joint.#
(b)Solvent cement joints. Each solvent cement joint on plastic pipe must comply with the following:#
(1)The mating surfaces of the joint must be clean, dry, and free of material which might be detrimental to the joint;#
(2)The solvent cement must conform to ASTM Specification D 2513; and#
(3)The joint may not be heated to accelerate the setting of the cement.#
(c)Heat-fusion joints. Each heat-fusion joint on plastic pipe must comply with the following:#
(1)A butt heat-fusion joint must be joined by a device that holds the heater element square to the ends of the piping, compresses the heated ends together, and holds the pipe in proper alignment while the plastic hardens;#
(2)A socket heat-fusion joint must be joined by a device that heats the mating surfaces of the joint uniformly and simultaneously to essentially the same temperature; and#
(3)Heat may not be applied with a torch or other open flame.#
(d)Adhesive joints. Each adhesive joint on plastic pipe must comply with the following:#
(1)The adhesive must conform to ASTM Specification D 2517; and#
(2)The materials and adhesive must be compatible with each other.#
(e)Mechanical joints. Each compression type mechanical joint on plastic pipe must comply with the following:#
(1)The gasket material in the coupling must be compatible with the plastic; and#
(2)A rigid internal tubular stiffener, other than split tubular stiffener, must be used in conjunction with the coupling. [Eff ] (Auth: HRS '269-6) (Imp: 49#
