July 2020: Revision of standards and validity of certificates
New product solutions, new technologies and requirements coming from revised regulations are some of many reasons to keep standards up to date. The updated edition will be published with a new release date.
With a product having been certified to the previous version of the standard, the question that is often asked is, will the product now have to be certified again, now using the new release of the standard. The Gas Appliances Advisory Committee had discussed this few years ago and put the result on a note which was then used by manufacturers and Notified Bodies to have a common understanding on how to react to a new release of a standard. With the Gas Appliances Directive being replaced by the Gas Appliances Regulation, the document was also withdrawn.
Afecor has based on information taken from the Blue Guide published an own document to support manufacturers and Notified Bodies in taking conscious decisons.
Afecor - Revision of Standards and Validity of Certificates
Afecor statement on designed lifetime of safety relevant controls updated
It is commonly understood that neither mechanical parts nor electronic components have an infinite lifetime. This becomes an issue for safety relevant products, which are typically assessed for their safety when they are new. Ageing an wear may change the assumptions that the assessment was based upon.
The standards for controls in our industry include endurance tests which represents a typical life span in heating applications. Afecor compiled the endurance test cycle specifications to give guidance for the product documentation to include statements on maintenance or replacement for products that reach the number of cycles or the corresponding time period.
The tables have been updated to reflect changes in the relevant standards.
