3.1 Certificate content

3.1 Certificate content

3.1 Certificate content

EN 10168:2004 states that:
"This European Standard lists the information that MAY be communicated in and includes a brief description of the inspection documents of steel products as described in EN 10204" and "by laying down standardized designations and definitions for information LIKELY to appear in inspection documents...".
My question is what information MUST be included in a 3.1 certificate for steel valves? For example, does it have to state anywhere on the document  'in accordance with EN10204 3.1', and are hand written amendments allowed e.g. if we machine a threaded valve to socket weld can we write on the certificate 'machined to socket weld'?
EN 10168:2004 can be interpreted as SUGGESTING what should be on the document, but exactly what is mandatory?
Any help gratefully received!

RE: 3.1 Certificate content

Conc. content of a 3.1 certificate, see EN 10204 par. 4.1:
"Document issued by the manufacturer in which he declares that the products supplied are in compliance with the requirements of the order and in which he supplies test results.  The test unit and the tests to be carried out are defined by the product specification, the official regulation and the corresponding rules and/or the order."
It is evident, that in the title of the document, there should appear "Inspection certificate 3.1 according EN 10204:2004"
Hand written amendments are not allowed with the exception, that intermediaries (that are per definition steel traders, stockists,..) may change the actual delivered quantity.
If you buy a steel product and transform it into a new product, you are the manufacturer of this new product and you can establish a 3.1 certificate only for this new product and you confirm the compliance of this product with the requirements of the order.  You certify the test results you carried out or those carried out by a lab assigned by you.  You join the 3.1 certificate of the products you bought.
