ISO 11734 Anaerobic Biodegradability under High-Solids Conditions

Comprehensive Guide to ISO 11734 Anaerobic Biodegradability under High-Solids Conditions Laboratory Testing Service

ISO 11734 is an international standard that governs the testing of anaerobic biodegradability under high-solids conditions. This standard provides a framework for evaluating the biodegradation of organic matter in the absence of oxygen, which is essential for assessing the environmental impact of various products and materials.

Relevant Standards

Standard Development Organizations

The development of international standards is a collaborative effort among various organizations. The International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), and other standard development organizations work together to create and update standards.

Evolution of Standards

Standards evolve over time as new technologies, methods, and testing protocols become available. ISO 11734 has undergone revisions since its initial publication in 1995, with the latest revision in 2005.
