ISO 11357-1 Plastics DSC General Principles Laboratory Testing Service: A Comprehensive Guide
ISO 11357-1 is a widely recognized international standard for the testing of plastics using Differential Scanning Calorimetry (DSC). This standard provides a framework for laboratories to perform accurate and reliable DSC tests on plastic materials. The standard is developed by the International Organization for Standardization (ISO) and is available in multiple languages.
International Standards Governing ISO 11357-1 Testing
Standard Development Organizations and Their Role
The International Organization for Standardization (ISO) is responsible for developing and maintaining the ISO 11357-1 standard. The ISO has a global network of member bodies that contribute to the development and approval of standards.
