Penetration level: As per EN/ISO 17636-1 For CS: ~30-200 mm (X-ray -1-4MeV Class A) ; ~50-180 mm (Class B- Inspector training). For DSS: Same above range as a base and to meet IQI. Penetration level: As per ASME sec. V For CS: No Specific limits. X-ray energy and technique to achieve required penetration and IQI sensitivity up to job thickness. For DSS: Same above and to meet IQI for the thickness used.

Dear experts, Kindly advise if any code or standard specify to use pressure chart recorder for piping spools hydrotest. The client asking to use it although it is not mentioned in the approved procedure/ITP. Please advise.
