ISO 22039 Heavy Metal Content in Packaging Substances

Comprehensive Guide to ISO 22039 Heavy Metal Content in Packaging Substances Laboratory Testing Service

Standard-Related Information

The laboratory testing service for heavy metal content in packaging substances is governed by various international and national standards. The primary standard applicable to this service is ISO 22039:2015, which specifies the requirements for the determination of the mass fraction of certain specified heavy metals in packaging materials.

Legislative Framework

The legal and regulatory framework surrounding this testing service is complex and multifaceted. In Europe, for instance, the European Unions (EU) Restriction of Hazardous Substances (RoHS) Directive 2011/65/EU sets limits on the concentration of certain hazardous substances in electrical and electronic equipment, including packaging materials.

International Standards

ISO 22039 is an international standard developed by the International Organization for Standardization (ISO). It has been adopted as a national standard by several countries, including those in Europe, North America, and Asia. The standard specifies the requirements for sampling, sample preparation, and analysis of heavy metal content in packaging materials.

Standard Development Organizations

The development of standards such as ISO 22039 is the responsibility of organizations like the International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), and the European Committee for Standardization (CEN). These organizations work collaboratively to develop, maintain, and publish standards that meet the needs of industries and stakeholders worldwide.

Standard Evolution and Update

Standards are constantly evolving as new technologies emerge, and scientific knowledge advances. Updates to existing standards ensure they remain relevant and effective in protecting human health and the environment. In 2020, for example, ISO published an updated version of ISO 22039 (2015), incorporating revised analytical methods and more stringent limits on heavy metal content.

Standard Compliance Requirements

Compliance with standards such as ISO 22039 is mandatory for industries involved in packaging materials production, importation, and exportation. Companies must demonstrate compliance through regular testing and certification by accredited laboratories. Failure to comply can result in fines, penalties, or even product recalls.
