Dear experts
I want to know about PTC in detail , when it’s required, what’s the relation b/w impact exemption and PTC
Thanks in Advance

In relation to which Code/Standad?
For what kind of product?
Pressure Vessel?
Power boiler part?

Field Test Coupon Procedure:
Simply take test coupons onto scaffold near the actual field weld. The test coupons must be of the same material and type etc and backed up with documentation. Set up test coupon in same position as actual field weld.This was the way we done production
test coupons in the past for ASME-Section VIII, DIV I when required.
I hope this helps

I am a 80 yr. old retired welding engineer and do not have access to code books etc. You asked about a field weld test coupon, what does USC-66 for impact exemption have to do with that.

1. What is the Purpose of PTC?
PTC Facilitates destructive testing of true representation of production welds for ascertaining mechanical properties
2. When PTC Required?- UCS 66
Whenever UCS 66 curves do not exempt impact testing of Parent Metal based on
A) MDMT ( Minimum Design Metal Temperature)
of equipment
B) Thickness Material
C) Curve representing Material Specification
& Grade
D) Whenever Customer Specification calls

Let me say this. The pressure vessels I was involved in required Production Test Coupons on each course from the bottom to the top.
The coupons had to be identical in every way to the actual pressure vessel CS impacted tested material and weld joints. The impacted tested CS plates were required by the code.
