BS EN ISO 4545-2:2017

Comprehensive Vickers Hardness Testing Standard

BS EN ISO 4545-2:2017 is the essential British Standard for Vickers hardness testing of metallic materials. This standard, identical to ISO 4545-2:2017, provides detailed guidelines and requirements for conducting Vickers hardness tests, ensuring consistent and reliable hardness measurements across a wide range of industries.

Ensuring Accurate, Reproducible Hardness Measurements

Vickers hardness testing is a crucial quality control and material characterization technique used extensively in the metalworking, automotive, aerospace, and other industries. BS EN ISO 4545-2:2017 specifies the test method, equipment, and procedures to be followed, enabling organizations to:

• Obtain accurate, reproducible Vickers hardness values for metallic materials
• Ensure consistent hardness testing practices across different laboratories and production facilities
• Comply with international standards and industry requirements for material hardness verification

Comprehensive Guidance for Vickers Hardness Testing

This British Standard covers all aspects of Vickers hardness testing, including:

• Test Principle: Detailed description of the Vickers hardness test method, which involves indenting the material surface with a diamond pyramid indenter and measuring the resulting impression diagonally.
• Test Conditions: Specifications for test force, dwell time, and other parameters to ensure consistent test conditions.
• Test Procedure: Step-by-step guidelines for preparing the test specimen, performing the indentation, and measuring the impression diagonally.
• Calculation and Expression of Results: Formulas and methods for calculating the Vickers hardness number from the measured impression diagonals.
• Test Report: Requirements for documenting and reporting the Vickers hardness test results, including relevant information about the test specimen and conditions.

Ensuring Compliance and Consistent Quality

By adhering to the requirements of BS EN ISO 4545-2:2017, organizations can:

• Demonstrate compliance with international standards for material hardness testing
• Ensure the reliability and reproducibility of Vickers hardness measurements across different locations and testing laboratories
• Maintain consistent quality control and material characterization practices throughout their operations
• Facilitate the exchange of hardness data and test results with customers, suppliers, and regulatory bodies

Whether you're a manufacturer, materials testing laboratory, or quality assurance professional, BS EN ISO 4545-2:2017 is an essential reference for conducting accurate and reliable Vickers hardness testing of metallic materials.
