Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 13822-1992 Specimens for nonferrous diecasting alloys.
Compared with GB/T 13822-1992, the major changes of this Standard are as follows:
-- Modify the pouring system and exhausting system of the process diagram of test
specimens for diecasting alloys, to be closer to the actual diecasting production;
-- Modify the arrangement of test specimens on the diecasting process diagram;
-- Add that diecasting enterprises can adjust diecasting process parameters according
to actual production conditions.
This Standard shall be under the jurisdiction of National Technical Committee 54 on
Foundry of Standardization Administration of China (SAC/TC 54).
The organization responsible for the drafting of this Standard: Guangdong Hongtu
(Nantong) Die-casting Co., Ltd.
Organizations participating in the drafting of this Standard: Zhejiang Huashuo
Technology Co., Ltd., CITIC Dicastal Co., Ltd., Sanmenxia Dicastal Wheel
Manufacturing Co., Ltd., Baoji Titanium Industry Co., Ltd., Xiongbang Die Casting
(Nantong) Co., Ltd., Dongfeng (Shiyan) Nonferrous Castings Co., Ltd.

-- GB/T 13822-1992.
Test specimens for nonferrous diecasting alloys
1 Scope
This Standard specifies the type, size and requirements of test specimens for nonferrous
diecasting alloys.
This Standard applies to the preparation of test specimens for mechanical property of
nonferrous diecasting alloys.
2 Normative references
The following referenced documents are indispensable for the application of this
document. For dated references, only the edition cited applies to this document. For
undated references, the latest edition (including any amendment) applies to this
document.
GB/T 231.1, Metallic materials - Brinell hardness test - Part 1: Test method
3 Type and size of test specimens
3.1 Tensile test specimen
3.1.1 Type A tensile test specimen
Type A tensile test specimen – whose shape and size shall comply with the regulations
in Figure 1 – applies to the determination of tensile strength, yield strength and
elongation of nonferrous diecasting alloys under different heat treatment states.
in millimeters
for nonferrous diecasting alloys. Diecasting enterprises can choose in Appendix A and
adjust the diecasting process parameters in Appendix B according to actual production
conditions.
4.2 The impact of low-speed diecasting, vacuum diecasting and other processes on the
preparation of test specimens are not taken into account in this Standard. If necessary,
the supplier and the purchaser can negotiate and agree on various technical
requirements in the preparation process of test specimens.
4.3 The test specimen shall be cast from nonferrous metal molten in the same batch as
the die casting.
4.4 The test specimen shall be cleaned of burrs, and shall not be bent and straightened.
According to the requirements of the delivery state of the casting, the same heat
treatment process shall be adopted for the test specimen and the casting.
4.5 The non-clamping part of the test specimen shall not have defects such as ejector
pin marks, scratches, pockmarks, cold shuts, cracks, inclusions and surface holes.
4.6 The two ends of the test specimen shall be ground and smoothed, and the feed port
and slag bag port shall be removed.
