SVHC Substance Testing in Aviation Components

SVHC Substance Testing in Aviation Components: A Comprehensive Guide

Overview of Relevant Standards

The regulation of Substances of Very High Concern (SVHC) in aviation components is governed by various international and national standards. The key regulatory framework includes:

1. REACH Regulation: Article 33 of the EUs Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation requires manufacturers to identify and communicate SVHCs present in their products.

2. EU RoHS Directive: The European Unions Restriction of Hazardous Substances (RoHS) directive restricts the use of certain hazardous materials in electrical and electronic equipment, including aviation components.

3. IEC 62321: This International Electrotechnical Commission standard provides a method for determining SVHC content in products.

Standard Development Organizations

The development and maintenance of standards are overseen by various organizations:

1. ISO (International Organization for Standardization): A global organization that develops and publishes international standards.

2. ASTM (American Society for Testing and Materials): An American organization that develops and publishes standards for a wide range of materials, products, and services.

3. EN (European Committee for Electrotechnical Standardization): The European organization responsible for developing and publishing electrotechnical standards.

Standard Evolution and Updates

Standards evolve through a continuous process of review and revision:

1. Revision Cycle: Standards are reviewed periodically to ensure they remain relevant and effective.

2. New Editions: Revised standards may be published as new editions, incorporating changes in technology or regulatory requirements.

3. Addenda: Supplemental documents that provide additional information or clarify existing requirements.

Standard Numbers and Scope

Key standard numbers and their scope include:

1. ISO 16143-1:2012(E): Determination of concentrations of SVHCs in materials.

2. ASTM D6487-00(2009): Standard test method for determination of extractable content by extraction with a solvent mixture (in aviation fuel).

3. EN 14341:2010: Screening for SVHCs in electrical and electronic equipment.

Industry-Specific Compliance Requirements

Compliance requirements vary across industries:

1. Aviation: EU Regulation No 2020/739 (EU RoHS III) restricts the use of certain hazardous materials.

2. Electronics: EU Directive 2011/65/EU (RoHS II) regulates the use of SVHCs in electrical and electronic equipment.

Business and Technical Reasons for Conducting SVHC Substance Testing

Conducting SVHC substance testing is essential for:

1. Ensuring Regulatory Compliance: Manufacturers must identify and communicate SVHC content to avoid penalties.
