Re: [MW:12355] 3.2 Certification Query / EN 10204:2004

Traceability:  You need not have the Test certificate of a Pipe material from which Fittings are made. But, you need to have Test certificate for Fittings from the manufacturer of the Fittings. You shall have to ensure Physical traceability from Fittings to this Fitting TC.

 

3.1 to 3.2 converstion:

 

1) Chemical Analysis -,Need to do chemical analysis from independent lab witnessed by TPI,

 

2) Mechanical Testing : Tensile test, (Yield load, tensile load), , percentage reduction, elongation test and hardness test are are required as a minimum .

 

Impact test shall be done only if required by product spectification of fittings.

 

I suggest that you may avoid flattening test(if required by product specification) in agreement with client

 

Thanks

Dear All,

 

We would like to know whether Pipe fittings (Elbow, Tee, Reducer etc…) can be certified to 3.2 Certification from the Base material which is a pipe.(Base material Certificate type is 3.1) and help us by providing what all testing and other requirements to be considered in Inspection Test Plan for Pipe fittings to be endorsed as Type "3.2".

 

Whether physical traceability of base material (in our case, it is carbon steel seamless pipe) at Manufacturer's location is required?

 

NOTE: All mechanical and chemical tests for fittings at an Independent Laboratory shall be done and will be certified by LR, BV etc…. so as to endorse Pipe fittings as "3.2 Certification".

Do we still require a complete traceability of Base Material Certificate; although above test will be done?

 

Please provide your technical guidelines to resolve above query.

 

Hope to see as usual positive response from eveyone.

 

Thanks & Regards
