Re: [MW:33534] Production Test Plate

Rather than giving a Fish to Eat, it is better to teach them fishing.

Just a proverb.

If it is for Production test coupon.

1. Charpy specimen size is 10x10x55 mm (width is 10mm).

2. I set of charpy specimen contains 3 number of specimen.

3. so calculate the total specimen and multiply with width.

4. Check with the charpy testing LAB the cutting allowance for specimen.

5. Put a rough check and calculate.

Please also check with the Lab as Lab people are very knowledgeable.

Thanks & Regards

Dear Gerald Sir,

Greetings!!

Please advise the dimensions of the test plate.

300 mm (W) x 500 mm (L) is enough.

In our case one test plate is required for each welding procedure used for Cat. A & B Joints.

80 mm thick dish heads are manufactured with a single joint - PTC is required for these joints.

Thank You & Regards

That's why we subjected it to the impact test.
What I want to learn is how many samples should be taken from where in the sourced material I want to specify below?

I will be glad, if you inform me.

Yours truly

When Impact testing is a design requirement as per ASME Sec.VIII Div.I, production Impact testing is required. Only Impact test is the requirement as per ASME Sec.VIII Div.I unless other tests are required by your Client Requirement.

For production Impact test follow below section.

For any specific requirement as per below table, please describe in detail what clarification you require.

Thanks & Regards

We design a pressure vessel according to ASME VIII Div.1 and our customer request shows "Production test plates according to Code requirements". Can you tell us the section showing where we can take samples from materials that vary according to their thickness. Or I need someone to contact me about the issue.
