Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part

1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 3159-2008 "Hydraulic Universal Testing Machine". Compared with GB/T 3159-2008, the main differences are in structural adjustments and editing. Aside from the logical changes, the main technical changes are as follows:

---The technical requirements for the Level 2 testing machine have been removed (see Chapter 5 of the.2008 edition);

---Added requirements and detection methods for zero-point drift (see 6.3.4, 7.4.2);

---Added requirements and testing methods for extensometer systems (see 6.4, 7.5);

---Displacement requirements and detection methods have been added (see

---The method for correcting noise detection results has been changed (see Table 6, Table 6 in the.2008 edition). Please note that some content in this document may involve patents. The issuing organization of this document assumes no responsibility for identifying patents. This document was proposed by the China Machinery Industry Federation.

1 Scope

GB/T 3159-2026 is the Chinese national standard covering the hydraulic universal testing machine - the press that pulls, compresses and bends specimens in every materials laboratory, with its force accuracy classes, its speed control, its grips and its safety. Every tensile result quoted in the other standards of this batch was measured on one of these. It replaces GB/T 3159-2008. It was issued on 27 February 2026 and has been in force since 1 September 2026, replacing GB/T 3159-2008. The document is under the responsibility of the China Machinery Industry Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the main parameter series and technical requirements for hydraulic universal testing machines, describes the corresponding testing methods, and stipulates the inspection procedures. Requirements for rules, markings and packaging, and accompanying technical documentation. This document applies to the manufacture of hydraulic universal testing machines (hereinafter referred to as "testing machines"). It covers hydraulic pressure testing machines and hydraulic tensile testing machines. The manufacturing process for testing the machine should be used as a reference.
