1、Designation:D396511Standard Classification System and Basis for Specifications forRigid Acrylonitrile-Butadiene-Styrene(ABS)Materials forPipe and Fittings1This standard is issued under the fixed designation D3965;the number immediately following the designation indicates the year oforiginal adoption
2、 or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This classification system covers materials made fromonly virgin ABS polymers and
3、blends of ABS polymerssuitable for use in the extrusion of pipe and molding of fittings.1.2 The requirements of this classification system are appli-cable only to the ABS polymers and blends of ABS polymersas classified and do not address the requirements of the finishedpipe or fittings.The applicab
4、le ASTM standard specificationfor pipe or fittings shall be consulted for their requirements.1.3 This classification system excludes ABS polymers andblends of ABS polymers made from reprocessed,regrind,reclaimed,or recycled materials.ABS rework,generated in-house by the original plastic manufacturer
5、,may be used by thatoriginal manufacturer,provided the ABS product shippedmeets the physical and mechanical properties required by itscallout in Table 1.1.4 This classification system and subsequent line callout(specification)provides a means for describing ABS materialsused in the manufacture of pi
6、pe and fittings.It is not intendedfor the selection of materials.Material selection shall be madeby those having expertise in the plastics field after carefulconsideration of the design and the performance required of thepart,the environment to which it will be exposed,the fabrica-tion process to be
7、 employed,the inherent properties of thematerial other than those covered by this classification system,and the economics.1.5 This classification system and subsequent line callout(specification)provides for the classification of ABS polymersand blends of ABS polymers into groups based on fiveproper
8、ties:Izod impact strength at room temperature,Izodimpact strength at low temperature,deflection temperatureunder load,tensile stress at yield point,and modulus ofelasticity in tension.The properties included are those requiredto identify the ABS material by the cell classifications.NOTE1Other requir
9、ements necessary to identify particular character-istics of ABS polymers and blends of ABS polymers will be added as testmethods become available or the need is identified.NOTE2Due to pipe and fitting standards requirements a separatestandard is planned for recycled materials.NOTE3This classificatio
10、n system and ISO 7245-1984 are not equiva-lent.1.6 The values stated in SI units shall be the standard.Thevalues given in parentheses are for information only.1.7 The following safety hazards caveat pertains only to thetest methods portion,Section 13,of this classification system-:This standard does
11、 not purport to address all of the safetyconcerns,if any,associated with its use.It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D2
