Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part

1.Structure and Drafting Rules for Standardization Documents" drafting. This document replaces GB/T 16491-2008 "Electronic Universal Testing Machine". Compared with GB/T 16491-2008, except for structural adjustment and Apart from editorial changes, the main technical changes are as follows:

---Changed the scope of application (see Chapter 1, Chapter 1 of the.2008 edition);

--- Changed the requirements for the bending test device and added the requirement that "the distance between the bending supports should be adjustable" (see 5.3.4.2,.2008 edition 5.3.4.2);

--- Changed the requirements for the zeroing and zeroing function of the force measuring system, and deleted the "zeroing" requirement (see 5.4.1.4,.2008 edition 5.4.1.4);

---Changed the requirements for the coaxiality tester of the inspection appliance, changing "±2%" to "±1%" (see 6.2,

6.2 of the.2008 edition);

---Changed the test conditions for the test of the test machine's resistance to transportation bumps (see 6.12,

6.12 of the.2008 edition);

--- Changed the judgment rules for type inspection (see 7.3.2,

7.3.2 of the.2008 edition). Please note that some contents of this document may refer to patents. The issuing agency of this document assumes no responsibility for identifying patents.

1 Scope

GB/T 16491-2022 is the Chinese national standard on electronic universal testing machines, in the field of testing. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 December 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2023. Classification: ICS 19.060, CCS N71. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the main parameter series, technical requirements, inspection methods, inspection rules, signs and packaging of electronic universal testing machines. This document is applicable to the design, manufacture and testing of electronic universal testing machines (hereinafter referred to as "testing machines") for testing the mechanical properties of metallic materials. test. The design, manufacture and inspection of the electronic universal testing machine for the mechanical performance test of non-metallic materials shall be carried out by reference.
