Overview
ASTM E110-14 is a Standard Test Method for Rockwell and Brinell hardness of metallic materials. This test method is applicable to defining procedures for using portable devices to measure Rockwell and Brinell hardness of large, immovable objects or in-situ metals when lab testing isn’t feasible or reliable, while ensuring field results align with fixed-tester results.
ASTM E110-14 is the revision of the ASTM E110 standard. Included herein are the modifications and improvements made to the original version. ASTM E110-14 refers to the fact that this edition was published in 2014. Updates to standards might relate to the following:
Scope, Applications, and Benefits
Scope
The ASTM E110-14 standard test method is used to determine Rockwell and Brinell hardness of metallic materials using a portable hardness tester. The test is essential when samples are too bulky or heavy to be assessed by traditional, immobile instruments. This standard provides procedures for testing hardness in configurations where standard lab configurations cannot be used. This will ensure that hardness test results are obtained with reasonable accuracy and reliability, even under non-standard laboratory conditions. This standard addresses the requirements for test equipment, specimen preparation, and data interpretation.
Applications
- Architectural glazing and building glass.
- Automotive glass components.
- Heat-resistant and safety glass evaluation.
- Glass is used in appliances and industrial equipment.
- Research and development of new glass compositions.
Benefits
- Provides a standardized method for determining the thermal shock resistance of glass.
- Helps predict glass performance under sudden temperature changes.
- Improves the safety and reliability assessment of glass products.
- Supports quality control during glass manufacturing.
- Assists in material selection for thermally demanding environments.
