ISO 22036 Extraction of Metals from PackagingISO 22036 Extraction of Metals from Packaging: Eurolabs Laboratory Testing Service
ISO 22036 is an international standard that governs the extraction of metals from packaging materials. This standard provides a framework for testing the extractable metal content in various types of packaging, including plastics, paper, and glass.
1.1 Legal and Regulatory Framework
The ISO 22036 standard is part of a broader regulatory framework aimed at ensuring the safety and quality of packaged goods. In many countries, regulatory agencies require manufacturers to demonstrate compliance with specific standards for extractable metal content in packaging materials.
1.2 International and National Standards
ISO 22036 is an international standard developed by the International Organization for Standardization (ISO). However, national standards organizations, such as ASTM in the United States or EN in Europe, may also publish equivalent standards that align with ISO 22036.
Table 1: Relevant Standards and Their Scope
Standard Title Scope
--- --- ---
ISO 22036 Extraction of metals from packaging Part 1: Determination of extractable metal content by acid digestion Specifies the method for determining the extractable metal content in packaging materials using acid digestion.
ISO 22036-2 Extraction of metals from packaging Part 2: Determination of extractable metal content by atomic absorption spectroscopy Specifies the method for determining the extractable metal content in packaging materials using atomic absorption spectroscopy.
1.3 Standard Development Organizations
Standard development organizations, such as ISO and ASTM, play a crucial role in developing and maintaining standards like ISO 22036.
