Standard Specification for
Styrene-Acrylonitrile (SAN) Injection and Extrusion

This standard is issued under the fixed designation D 4203; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the 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 unfilled, filled, and reinforced
styrene acrylonitrile (SAN) materials suitable for injection
molding and extrusion.

1.2 This specification is not intended for the selection of
materials, but only as a means of calling out materials to be
used in the manufacture of parts. Materials are to be selected
by personnel with expertise in the plastics field where the
economics, the environment to be encountered, the inherent
properties of the materials, the part design, the part performance required, and the manufacturing process to be employed
all enter into the selection.

1.3 The properties included in this specification are those
required to identify the compositions covered. There may be
other requirements necessary to identify particular characteristics important to specialized applications. These will be
agreed upon between the user and the supplier, by using the
suffixes specified in Section 7.

1.4 The values stated in SI units are to be regarded as the
standard. The values in parentheses are given for information
only (see IEEE/ASTM SI 10.)

1.5 The following precautionary caveat pertains only to the
test methods portion, Section 15, of this specification: This
standard does not purport to address all of the safety concerns,
if any, associated with its use. It is the responsibility of the user
of this standard to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use.
NOTE 1—Although this specification and ISO 4894/1 differ in approach
or detail, data obtained using either are technically equivalent.
