Charpy temp

[mteg]

I am wanting to do some charpy test for welds on X52-X60 material. ASME references SA-370 but don't have access to this standard. To what temp should I test?

 

[metengr]

ASTM/ASME A/SA 370 refers to testing of steel products, and does not provide test temperatures. The CVN impact test temperatures are either provided by the code of construciton or by engineering specification.

 

[mteg]

We don't have this requirement specified in any of our engineering specifications. Where can I find guidance or recommended test temps?

 

[metengr]

mteg;
What is the code of construction for this application? Is it ASME B31.1, 31.3? This is whaere you would find the necessary test temperatures.

 

[blacksmith37]

API 5L has Supplemental Requirement 5 for testing procedures; but the purchaser still needs to define requirements.

 

[zebmahar]

According to API 5L X52-X60 PSL 2 these can be tested at -23 C and it is written in API 5L 44th eddition

The purchaser is required to give this data along with the acceptance criteria. Even if you test to -23°C, what would be the minimum acceptable for (1) specimen or the average of (3)? You wouldn't know this without the purchaser defining this for you.
