Sperko Engineering 2005WWW.SPERKOENGINEERING.COMStandard Test PositionsPositions 1G, 3G, 6G, 2F, 5F, etc. are specially defined standard positions used for testing. They are properly referred to as Test Positions. Similar positions are found in ISO 6947 identified as PA, PC, PG, etc.
WWW.SPERKOENGINEERING.COM
Sperko Engineering 2005WWW.SPERKOENGINEERING.COMStandard Testing PositionsTest positions are discreetly defined positions of test coupons that are used when mostly when testing welders. These positions have tolerance of 15 from the defined horizontal planes and 5 from a defined vertical or inclined plane. See QW-120

WWW.SPERKOENGINEERING.COM
Sperko Engineering 2005WWW.SPERKOENGINEERING.COMTest Positions are Discreetly DefinedBecause of tolerance limits on test positions, positions in between test positions are undefined!That is, a weld that is inclined 22 uphill and rotated 36 about its axis has no G or F position. Such a position, however, may be encountered during production welding. Production welding positions, therefore, need to be defined contiguously.
