--Most common materials require 1 hour/25mm or 60minutes/25mm and I assume you are working with one of these materials. Then, for a 40mm thick material the required minimum soak time is (40mm)*(60min.)/(25mm) = 96 minutes
You don't meet Code required minimum soak time. Your soak time must exceed the minimum time. Therefore, your pipe weld is unacceptable. No discussion – it is clearly unacceptable in its present condition.

Subject: [MW:14919] Stress relieving Rejected for 5 min less soaking time.
Dear expert,
As per ASME 8-1-UCS-56
We have done SR for our 40mm thk-30" pipe joint.
but unfortunetly, soaking time was just short by 5min.Now our client/PMC both are not agree to release.
Required time : 1hr.15min
Actual Time : 1hr.10min
It is acceptable OR could you share any technical view to convince client?
regards,
mohd.
