What is BS EN ISO 2082:2019?

BS EN ISO 2082:2019 is a technical standard that specifies the requirements for determination of indenter impression hardness of metallic materials using Rockwell and Superficial Rockwell hardness testers. This standard provides guidelines for testing the hardness of metallic materials, which is an important parameter in assessing their mechanical properties.

Understanding the Importance of Hardness Testing

Hardness testing is a vital tool in evaluating the quality and performance of metallic materials. It measures the material's resistance to permanent deformation when subjected to an applied force. The evaluation of hardness assists in determining whether a material is suitable for a specific application or if it undergoes any changes during manufacturing processes such as heat treatment or surface hardening.

The Rockwell and Superficial Rockwell Hardness Testing Methods

The BS EN ISO 2082:2019 standard focuses on two commonly used hardness testing methods: Rockwell and Superficial Rockwell. The Rockwell method utilizes a diamond cone indenter or a steel ball while the Superficial Rockwell method employs a smaller diamond cone indenter with lighter loads. Both methods involve applying and removing an initial minor load followed by a major load, and then measuring the depth of the resulting indentation. The value obtained represents the hardness number of the material tested.

Adhering to BS EN ISO 2082:2019 for Accurate Hardness Testing

To ensure accurate and reliable hardness testing, it is crucial to follow the guidelines outlined in BS EN ISO 2082:2019. The standard specifies requirements for the test equipment, calibration, and recording of results. Proper sample preparation, including flatness and surface quality, is also essential for obtaining accurate measurements. Adhering to this standard guarantees consistent and comparable hardness values across different laboratories and industries.
