Foreword
This standard is equivalent to using ASTMD953.2002 (English Version) "plastic bearing strength test methods", were part of the editorial changes and
He removed the imperial units, identical in technical content.
This standard replaces GB/T 14484-1993 "plastic bearing strength test method", compared with the GB/T 14484-1993 Main within
Yung changes as follows.
a) the standard name changed from "" plastic bearing strength test method "" to "" determine the strength of the plastic carrier '';
b) an increase of Contents Preface;
c) increase the "meaning and use 4";
d) increasing the compression load and tensile load schematic;
e) improve the accuracy of the sample size;
f) increased accuracy.
Appendix A of this standard is a normative appendix, Appendix B is an informative annex.
