Standard Specification for
Rigid Acrylonitrile-Butadiene-Styrene (ABS) Materials for
Pipe and Fittings1

This standard is issued under the fixed designation D 3965; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope *

1.1 This specification covers materials made from only
virgin ABS polymers and blends of ABS polymers suitable for
use in the extrusion of pipe and molding of fittings.

1.2 The requirements of this specification are applicable
only to the ABS polymers and blends of ABS polymers as
classified and do not address the requirements of the finished
pipe or fittings. The applicable ASTM standard specification
for pipe or fittings should be consulted for their requirements.

1.3 This specification excludes ABS polymers and blends of
ABS polymers made from reprocessed, regrind, reclaimed, or
recycled materials. ABS rework, generated in-house by the
original plastic manufacturer, may be used by that original
manufacturer, provided the ABS product shipped meets the
physical and mechanical properties required by its callout in
Table 1 of this specification.

1.4 This specification provides a means for describing ABS
materials used in the manufacture of pipe and fittings. It is not
intended for the selection of materials. Material selection
should be made by those having expertise in the plastics field
after careful consideration of the design and the performance
required of the part, the environment to which it will be
exposed, the fabrication process to be employed, the inherent
properties of the material other than those covered by this
specification, and the economics.

1.5 This specification provides for the classification of ABS
polymers and blends of ABS polymers into groups based on
five properties: Izod impact strength at room temperature, Izod
impact strength at low temperature, deflection temperature
under load, tensile stress at yield point, and modulus of
elasticity in tension. The properties included in this specification are those required to identify the ABS material by the cell
classifications.
NOTE 1—Other requirements necessary to identify particular characteristics of ABS polymers and blends of ABS polymers will be added as test
methods become available or the need is identified
