1、Designation: F 656 02An American National StandardStandard Specification forPrimers for Use in Solvent Cement Joints of Poly(VinylChloride) (PVC) Plastic Pipe and Fittings1This standard is issued under the fixed designation F 656; the number immediately following the designation indicates the year o
2、foriginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers requirements for primers foruse
3、 with poly(vinyl chloride) (PVC) pipe and fittings that are tobe joined by PVC solvent cements meeting the requirements ofSpecification D 2564.1.2 These primers are used in pressure and nonpressureapplications with plain end pipe and either socket-type fittingsor bell end pipe. These primers prepare
4、 the surface of pipe andfittings before the application of solvent cement. The primerseffect on the set and cure time of the joint is dependent on thecement, pipe size, application method, temperature, and hu-midity.1.3 Aprocedure for using the primer with cement is given inPractice D 2855.1.4 The t
5、ext of this specification references notes, footnotes,and appendixes which provide explanatory material. Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.5 The values stated in inch-pound units are to be regardedas the sta

11、rements4.1 The primer shall be an organic liquid with water-likeviscosity and shall not contain any undissolved particles.4.2 The solvent system to be used in the formulation of thisprimer is not specified.NOTE 1If required for identification purposes, colorants shall be usedin the primer. It is rec
12、ommended that orange not be used, since this is therecommended color for CPVC solvent cement covered under Specifica-tion F 493.5. Detail Requirements5.1 Dissolving AbilityThe primer shall be capable ofdissolving at least 10 % by weight of PVC resin at 73.4 63.6F (23 6 2C) within 60 min, as specifie
13、d in 5.1. The PVCresin shall be a resin used to make poly(vinyl chloride)molding or extrusion compound meeting the requirements ofClass 12454-B, as classified in Specification D 1784.1This specification is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct respon

Test Methods6
16、.1 Dissolving Ability:6.1.1 Weigh 270 g of the primer being tested into a closedmixing container. Weigh out 30 g of PVC resin. Adjust thetemperature of the primer to 73.4 6 3.6F (23 6 2C). Beginmixing the primer, using a laboratory mixer designed formixing flammable liquids. Add the resin to the pri
17、mer andcontinue mixing for 60 min at a mixing speed of 1500 r/min orless, using a mixing blade and speed so that the maximumtemperature of the mixture during the mixing period is 90F(32C) or less. After 60 min, turn off the mixer and adjust thetemperature to 73.4 6 3.6F (23 6 2C).6.1.2 Visually obse
18、rve whether the resin is completelydissolved. The solution shall be smooth, nongrainy, free-flowing, and shall not contain any undissolved resin.6.2 StabilityHold the resin-primer solution at 40F (5C)for 24 h and then observe that (1) the resin is still completelydissolved, (2) the solution is free
19、flowing, and (3) there are nosigns of stringiness or gelatin structure.7.
