In the absence of harmonized standards, the manufacturer shall refer to an existing document (draft standard candidate for harmonization, professional document, guide, recognised third party/notified body document, company document) or shall establish a specific document.
Such a document shall define at least:
- essential variables for the procedure that may affect the properties of the permanent joining;
- inspection and testing to be carried out for the qualification of the procedure;
- acceptance criteria;
- range of validity.
Note:
The directive states that “the properties of permanent joints must meet the minimum properties specified for the materials to be joined unless other relevant property values are specifically taken into account in the design calculations”.
