ASTM D6990 Antimicrobial Performance of Packaging Polymers

ASTM D6990 Antimicrobial Performance of Packaging Polymers Laboratory Testing Service: A Comprehensive Guide

The ASTM D6990 standard is a widely recognized and accepted testing method for evaluating the antimicrobial performance of packaging polymers. This standard is designed to provide a comprehensive assessment of a materials ability to inhibit the growth of microorganisms, thereby ensuring the safety and integrity of packaged goods.

Legal and Regulatory Framework

The legal and regulatory framework surrounding ASTM D6990 testing is governed by various national and international standards. In the United States, the Food and Drug Administration (FDA) regulates food packaging materials under 21 CFR Part 176, which requires that packaging materials be safe for their intended use and do not pose a risk to human health.

Similarly, in the European Union, the Regulation (EU) No 1935/2004 on materials and articles intended to come into contact with food sets out requirements for the safety assessment of food contact materials. The EUs Directive 2011/65/EU on the restriction of the use of certain hazardous substances in electrical and electronic equipment also applies to packaging materials.

International and National Standards

The international standards that apply to ASTM D6990 testing include:

National standards, such as ASTM D6990 itself, provide specific requirements for testing and evaluation.

Standard Development Organizations

The development of international and national standards is overseen by organizations such as the International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), and the European Committee for Standardization (CEN). These organizations work together to ensure that standards are aligned and consistent across regions.

Evolution of Standards

Standards evolve over time as new technologies emerge, and consumer needs change. The development process typically involves:

1. Identifying a need or gap in existing standards

2. Gathering stakeholder input and feedback

3. Developing a draft standard through a consensus-based process

4. Reviewing and approving the final standard

Standard Numbers and Scope

Some relevant standard numbers and their scope include:

Compliance Requirements

Packaging manufacturers must comply with relevant standards to ensure their products meet regulatory requirements. Non-compliance can result in product recalls, fines, or even business closure.
