Overview

The EN 60068-2-75:2014/A1:2025 standard defines the procedures for environmental testing using hammer tests, specifically labeled as Test Eh. Prepared by the CLC organization, this standard serves as an amendment to the original EN 60068-2-75:2014, incorporating updates relevant for 2025 that primarily impact the French version. Hammer tests are critical for assessing the mechanical robustness and durability of materials and components under impact conditions.

This standard falls under the broader scope of environmental testing methods for electrical and electronic equipment, aligned with international best practices to ensure product reliability in various environmental conditions. It provides detailed specifications on test methods, hardness requirements, and sample materials, essential for manufacturers and quality assurance professionals.

Key Topics

• Test Eh: Hammer Tests
  Hammer tests simulate impact forces on materials and components by delivering controlled hammer blows. This helps evaluate a product’s ability to withstand mechanical shocks without failure.

• Hardness Specifications
  The amendment updates hardness criteria for materials under test:

  • Rockwell-hardness (HRR) ranging from 85 to 100 in accordance with ISO 2039-2, or Shore D hardness between 70 and 85 as per ISO 48-4.
  • Materials like Polyamide PA6.6 serve as examples for testing samples.
  • Steel specifications such as Fe 490-2, with Rockwell hardness HRE from 80 to 85 (ISO 6508-1), or HRBW between 69 and 91, exemplified by stainless steel grades like X6Cr17 (AISI 430).

• Amendment Details
  The corrigendum refines test conditions and clarifies hardness measurement standards to ensure consistency across testing laboratories. This underlines the document’s commitment to harmonized, precise test execution.

• Committee and Voting Process
  Developed under IEC TC 104, responsible for environmental conditions and testing methods, the amendment reflects collaborative international input with a projected stability date of 2028.

Applications

EN 60068-2-75:2014/A1:2025 is crucial for industries requiring robust environmental testing protocols, including:

• Electronics Manufacturing
  Ensures devices can endure mechanical impact during handling, shipping, and operational use without functional degradation.

• Automotive and Aerospace
  Verifies the durability of components exposed to vibrations and shocks, thereby improving safety and longevity.

• Material Science and Engineering
  Supports material selection by providing empirical data on impact resistance, facilitating development of tougher polymers and metals.

• Quality Assurance
  Offers standardized guidelines for laboratory equipment calibration and product validation to meet regulatory and market demands.

Related Standards

• EN IEC 60068-2 Series
  Covers various environmental test methods, including temperature, vibration, and humidity tests complementing hammer impact testing.

• ISO 2039-2
  Specifies hardness testing procedures for plastics, directly referenced within EN 60068-2-75:2014/A1:2025 for Rockwell-hardness evaluation.

• ISO 48-4
  Defines Shore hardness measurement methods for elastomers and plastics, integral to approving test sample materials.

• ISO 6508-1
  Pertains to Rockwell hardness tests for metallic materials, providing standardized procedures essential for steel component testing.

• ISO 1052
  Relates to steel classification (e.g., Fe 490-2), used in defining acceptable materials for durability testing.
