1 Scope

GB/T 22677-2008 is the Chinese national standard on electric impact wrenches, in the field of manufacturing engineering. 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 31 December 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 October 2009. Classification: ICS 25.140.20, CCS K64. 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 standard specifies the basic parameters of the electric impact wrench, type, technical requirements, test methods and inspection rules. This standard applies to general environmental conditions, the impact of the use of the clutch mechanism, the use of impact moment to complete assembly and disassembly of threaded member with electric shocks Wrench (hereinafter referred to as electric wrench). This standard does not apply to constant torque (current-controlled) and constant torque constant angle (current angle control type) electric wrench, electric wrench long modular Other dedicated electric wrench hand and mounting special type of threaded part (such as electric ratchet wrench, shear electric wrench, etc.).
