ISO 846 Evaluation of Fungal Resistance on Packaging Plastics

Comprehensive Guide to ISO 846 Evaluation of Fungal Resistance on Packaging Plastics Laboratory Testing Service

The ISO 846 standard is a widely recognized international standard that evaluates the fungal resistance of packaging plastics. This standard is developed and published by the International Organization for Standardization (ISO) to provide a framework for testing the biodegradation and fungal resistance of various materials, including packaging plastics.

Legal and Regulatory Framework

The legal and regulatory framework surrounding ISO 846 testing is governed by international and national standards. In Europe, the European Unions (EU) Regulation on Packaging Waste Directive sets out the requirements for packaging waste management, including the need for packaging to be biodegradable or compostable. Similarly, in the United States, the U.S. Environmental Protection Agency (EPA) regulates packaging materials under the Resource Conservation and Recovery Act (RCRA).

International and National Standards

The ISO 846 standard is complemented by other international and national standards that govern specific aspects of packaging plastics testing. For example:

These standards provide a framework for ensuring that packaging plastics meet specific performance criteria, including fungal resistance.

Standard Development Organizations

The development and maintenance of standards such as ISO 846 are the responsibility of standard development organizations (SDOs). SDOs bring together experts from industry, academia, and government to develop and maintain standards. The most well-known SDO is the International Organization for Standardization (ISO).

Evolution of Standards

Standards evolve over time as new technologies and regulations emerge. For example, the EUs Packaging Waste Directive has led to changes in the requirements for packaging materials, including biodegradability and compostability.

Standard Numbers and Scope

Some relevant standard numbers and their scope are:

Defines methods for testing fungal resistance of plastics
