Introduction

GB/T 43432 "Barcol Hardness Test of Metal Materials" aims to standardize the test methods and inspection of test instruments for Barcol hardness: It is planned to be composed of three composed of parts: ---Part 1: Test methods: The purpose is to establish the procedures and methods to be followed for Barcol hardness testing: ---Part 2: Inspection and calibration of hardness tester: The purpose is to stipulate the technical requirements and inspection and calibration methods that the Barcol hardness tester must meet: Law: It stipulates the direct inspection method for testing the basic functions of the hardness tester and the indirect inspection method for testing the comprehensive performance of the hardness tester: ---Part 3: Calibration of standard hardness blocks: The purpose is to determine the technical requirements and calibration methods that the Barcol standard hardness block needs to meet: Barcol hardness test of metal materials Part 2: Inspection and Calibration of Hardness Testers

1 Scope

This document describes the method of testing the Barcol hardness tester (hereinafter referred to as the "hardness tester") using the direct inspection method and the indirect inspection method, and stipulates the Barcol hardness tester: Hardness tester classification, general requirements, direct inspection method, indirect inspection method, inspection cycle and inspection report requirements: This document is applicable to the inspection and calibration of the Barcol hardness tester: The indirect inspection method can also be used independently for regular routine use of the hardness tester: test:

2 Normative reference documents

The contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document: GB/T 4340:1 Vickers hardness test of metallic materials Part 1: Test methods GB/T 36416:1 Testing machine vocabulary Part 1: Material testing machines GB/T 43432:3 Barcol hardness test of metallic materials Part 3: Calibration of standard hardness blocks

3 Terms and definitions

The terms and definitions defined in GB/T 36416:1 apply to this document:

4 Principle of Barcol hardness test

A steel indenter with a specified shape is pressed into the surface of the sample under the action of spring force: The depth of the indenter pressed into the sample is used to indicate the barometer of the material: degree of hardness: The hardness of the material is related to the depth of indentation: The shallower the indentation depth, the higher the hardness, and vice versa: Define every 0:0076mm The penetration depth is one Barcol hardness unit: Calculate Barcol hardness according to formula (1): HBa=100- 0:0076 (1) In the formula: HBa---Barcol hardness value; d ---The depth of the indenter pressed into the sample, in millimeters (mm):

5 Hardness Tester Classification

The cone angle of the pressing needle and the nominal value of the force spring coefficient divide the hardness tester into three types: Type A, Type B and Type C: The parameters corresponding to each type are See Table 1 for values: ......
