Comprehensive Guide to EN 62321-5 Mercury Analysis in Lighting Products Laboratory Testing Service Provided by Eurolab

EN 62321-5 is a European Standard for mercury analysis in lighting products, which was published in March 2019. This standard is part of the IEC 62321 series, which provides methods for measuring the content of certain hazardous substances in electrical and electronic equipment.

Legal and Regulatory Framework

The European Union (EU) has implemented various regulations to reduce the environmental impact of electrical and electronic equipment. The Restriction of Hazardous Substances (RoHS) Directive, Directive 2011/65/EU, sets limits for the concentration of hazardous substances in electrical and electronic equipment. Mercury is one of the restricted substances, with a maximum permitted concentration of 0.1 by weight.

International and National Standards

EN 62321-5 is based on ISO 11885:2007 (Determination of mercury content - Sampling method) and ASTM E3008-17 (Standard Test Method for Mercury in Materials). This standard is also harmonized with the EU RoHS Directive and is recognized by the European Commission as a valid method for measuring mercury content.

Standard Development Organizations

The development of EN 62321-5 was coordinated by CENELEC (European Committee for Electrotechnical Standardization), which is responsible for preparing and publishing technical standards in Europe. CENELEC works closely with other standard development organizations, such as IEC (International Electrotechnical Commission) and ISO (International Organization for Standardization).

Standard Evolution and Update

Standards evolve over time to reflect new technologies, scientific research, and regulatory requirements. EN 62321-5 is a revision of the previous standard, which was published in 2006. The latest version incorporates improvements to the measurement method, increased accuracy, and enhanced user safety.

Specific Standard Numbers and Scope

EN 62321-5:2019 (Mercury analysis - Part 5: Mercury content in lighting products) is a European Standard that provides a method for measuring mercury content in lighting products. The scope of this standard includes:
