This document replaces GB/T 4074:1-2008 "Winding wire test methods Part 1: General provisions" and is compatible with GB/T 4074:1-2008
Compared with the previous version, in addition to structural adjustments and editorial changes, the main technical changes are as follows:
--- Added the definition of "curing" (see 3:1:8);
--- Added the definition of "zero defect winding wire" (see 3:1:18);
--- Deleted "Type test (T)" (see 3:17 of the:2008 edition);
--- Deleted "sampling experiment (R)" (see 3:18 of the:2008 edition);
--- Deleted the definition of "routine test (S)" (see 3:19 of the:2008 edition);
--- Changed the temperature and humidity ranges in the general test method (see 3:2, Chapter 3 of the:2008 edition):
This document is equivalent to IEC 60851-1:2021 "Test methods for winding wires - Part 1: General provisions":
The following minimal editorial changes were made to this document:
--- In order to coordinate with the existing standards, the name of the standard is changed to "Winding Wire Test Methods Part 1: General Provisions":

Introduction
Winding wire is one of the main raw materials for power, motor, electrical appliances, home appliances, electronics, communications, transportation, power grid, aviation and other fields:
It has a wide range and covers many fields, and has become an important mechanical industrial product:
GB/T 4074 Winding Wire Test Methods is the only test method standard for measuring winding wire products in China: It is very important for product testing and market regulation:
It plays an important role in both market and product improvement:
GB/T 4074 aims to establish the test method standards for the performance of different types of winding wire products and is intended to consist of the following 9 parts:
--- Part 1: General provisions: The purpose is to establish the terms, definitions and general test principles for winding wire test methods:
--- Part 2: Dimensional measurement: The purpose is to establish test methods for measuring the dimensions of different products of winding wire:
--- Part 3: Mechanical properties: The purpose is to establish test methods for the mechanical properties of different types of winding wire products:
--- Part 4: Chemical properties: The purpose is to establish test methods for the chemical properties of different types of winding wire products:
--- Part 5: Electrical properties: The purpose is to establish test methods for the electrical properties of different types of winding wire products:
--- Part 6: Thermal properties: The purpose is to establish test methods for the thermal properties of different types of winding wire products:
--- Part 7: Test method for determining the temperature index of enameled winding wire: The purpose is to establish a method for determining the temperature index of enameled winding wire:
experiment method:
--- Part 8: Test method for determining the temperature index of enameled winding wire: Rapid method: The purpose is to establish the determination of the temperature index of enameled winding wire:
Rapid test method for the temperature index:
--- Part 21: High-frequency impulse voltage resistance performance: The purpose is to establish the test method for the high-frequency impulse voltage resistance performance of winding wires:
