Cold Chain and Refrigeration Standards
Cold Chain and Refrigeration Standards

The World Health Organization (WHO) has created many performance specifications for different categories of refrigerators and freezers used by health-care facilities. It also lists the products of companies that comply with these specifications.

Standards are norms or requirements that establish a basis for the common understanding and judgment of materials, products, and processes. Standards are an invaluable tool in industry and business, because they streamline business practices and provide a level playing field for businesses to develop products and services. They are also critical to ensuring that products and services are safe for consumers and the environment.

In order to help designers and implementers of cold chain equipment, the World Health Organization (WHO) has developed a number of standards for equipment used to store, transport, and monitor cold chain–dependent products. These standards provide a basis for the procurement of quality equipment designed to meet the stringent specifications necessary for a robust and effective  Cold Chain and Refrigeration storage infrastructure.

The following table lists each of the relevant WHO standards by category. Each listing is also a link to the standard itself. Additionally, a link to a listing of equipment prequalified by WHO is provided for each category.

Note: Standards E01, E03, and E04 are applicable only to vaccine cold chain equipment, as blood has different cold chain requirements.
