Can expired standards still be used?

No, expired or withdrawn technical standards cannot safely or legally be relied upon as active proof of regulatory compliance for consumer products in the United States, Canada, or the European Union. When a standard (such as an ASTM, CSA, or EN standard) is superseded or withdrawn, regulatory bodies expect products to conform to the latest updated criteria to mitigate safety risks.

United States (CPSC):

• Mandatory vs. Voluntary: The U.S. Consumer Product Safety Commission (CPSC) enforces mandatory federal standards. If a specific version of a standard is incorporated into federal law, using an expired version is a regulatory violation.
• General Conformity: For voluntary consensus standards (e.g., ASTM), relying on an expired standard fails to demonstrate due care if a product causes harm or is scrutinized for being unsafe.

Canada (Health Canada):

• General Prohibition: Under the Canada Consumer Product Safety Act (CCPSA), it is illegal to manufacture, import, or sell a consumer product that is a danger to human health or safety.
• Standard Updates: Health Canada regularly updates references to technical specifications. Using obsolete or expired standards leaves companies liable because compliance must reflect current state-of-the-art safety levels.

European Union (EU):

• Harmonized Standards: Under the General Product Safety Regulation (GPSR) and specific directives, manufacturers must ensure products are safe.
• Loss of Presumption: When an EU harmonized standard expires or is withdrawn from the Official Journal of the European Union (OJEU), it instantly loses its “presumption of conformity.” Using an old standard means you no longer have legal backing that your product meets EU essential safety requirements.
