One can always go above and beyond code minimum requirements. The only example I have seen for hardness testing in ASME Section IX concerns temper bead welding. Hardness testing and impact testing are considered essential variables in QW-290.4 to assure that the base metal heat affected zone has been tempered.~.j 'd ASME B31.3 INTERPRETATIONS NO. 15 Replies to Technical Inquiries April 1, 1996, Through March 31, 1997 General Information Ithas been agreed to publish interpretations issued by theB31 Committeeconcerning B31.3 as part oftheupdateservice to theCode.

In 2012, Quality Testing, Inc. acquired a wrap around bend testing machine developed by Triangle Engineering, Inc. to perform all of our guided bend testing in accordance with ASTM A370, E190, ASME IX, and API 1104 specifications. ASME IX does not require hardness testing. ASME IX allows a reduction in preheat of 55OC before requalification is required. ISO 15614 Pt1 does not permit any reduction in preheat from that used .
Weld coupon size for Procedure qualification & hardness test
In 2004, ASME Section IX added maximum hardness essential variables for temper bead procedure qualification when impact testing is not specified or required by the applicable book section. The assumption with specifying a maximum hardness criterion is that high hardness after temper bead welding indicates inadequate tempering. As discussed in .

In 2004, ASME Section IX added hardness testing for temper bead procedure qualification when impact testing is not required. The Eurocode, ISO standards, and numerous other European specifications .
Method A is based on the increase in tensile stress during load application. In the linear elastic part of the tensile test, that is at the very beginning of the test, the rate of stress application must be between 1.15 and 11.5 MPa/sec (this corresponds to 10000 and 100000 psi/min).; However, it is clearly stated in ASTM E8 and ASTM E8M that these specifications and method do not . Section IX of the ASME Boiler and Pressure Vessel Code Overview. The forms listed below form the basis for verifying welding procedures and welder performance: . Furthermore, test coupons, the removal of test specimens, and the test jig dimensions are identified. Article V - Standard Welding Procedure Specifications (SWPS) QW-500.
