Sterility and Microbial Limit Testing Laboratory Testing Service: A Comprehensive Guide
Sterility and Microbial Limit Testing is a critical laboratory test service that ensures the sterility and purity of products, particularly in the pharmaceutical, biotechnology, medical device, and food industries. This test is governed by various international and national standards, which are continually evolving to meet the changing needs of these industries.
International Standards
National Standards
Standard Development Organizations
The International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), and the European Committee for Standardization (CEN) are leading standard development organizations in this field. These organizations work closely with industry experts, regulatory bodies, and other stakeholders to develop and revise standards.
Standard Evolution and Update
Standards evolve and get updated regularly to reflect advances in technology, changes in regulations, and emerging industry needs. For example, ISO 11137:2012 replaced the earlier version (ISO 11137:2006) to incorporate new requirements for validation and routine control of sterilization by moist heat.
Standard Compliance Requirements
Compliance with relevant standards is mandatory for industries that require sterility testing. Non-compliance can lead to product recalls, reputational damage, and even regulatory penalties.
