Dear Kumar
I think you can’t use WPS for BS material following QW-424 ASME section 9

You can use if the client specify you(Go through client Standard) the equivalent ASTM material for the BS or any other material and the equivalent material falls under your qualified material range.

For EN - Variable Essential:
Process 12
- Each variant of process 12 (121 to 125) shall be qualified independently. - The qualification given for the flux is restricted to the make and designation used in the welding procedure test.
Processes 131, 135, 136 and 137
The qualification given to the shielding gas is restricted to the symbol of the gas according to EN 439. However, the content of CO2 shall not exceed 10 % of that used to-
qualify the procedure test. Shielding gases not covered by EN 439 are restricted to the nominal composition used in the test.
-
The qualification given is restricted to the wire system used in the welding procedure test (e.g. singlewire or multiple-wire system).-
For solid and metal cored wires, the qualification using short circuiting transfer (dip) qualifies only short circuiting transfer (dip). Qualification using spray or globular transferqualifies both spray and globular transfer.
Process 141
The qualification given to the shielding gas and backing gas is restricted to the symbol of the gas according to EN 439. Shielding gases not covered by EN 439 are-
restricted to the nominal composition used in the test.
-
A weld procedure test made without a backing gas qualifies a welding procedure with backing gas.-
Welding with filler material does not qualify for welding without filler material or visa versa.
Process 15
- Qualification of the welding procedure is restricted to the plasma gas composition used in the welding procedure test. - The qualification given to the shielding gas and backing gas is restricted to the symbol of the gas according to EN 439. Shielding gases not covered by EN 439 are
restricted to the nominal composition qualified.
- W
elding with filler material does not qualify for welding without filler material or visa versa.
Process 311
- Welding with filler material does not qualify for welding without filler material or visa versa.
.
FOR ASME (SMAW) - Variable Essential
- Essential Variable - QW403.8 = T Qualified, QW403.9 = t Pass > 1⁄2 in. (13 mm), ,QW403.11 = P-No. qualified
- Supplimentry Essesntial Vriable - QW403.5 = Group Number, ,QW403.6 = T Limits impact
- Supplimentry Essesntial Variable - QW404.7 = Diameter > 1⁄4 in. (6 mm), ,QW404.12 = Classification
- Supplimentry Essesntial Variable - QW405.2 = Position
- Essential Variable - QW406.1 = Decrease > 100°F (55°C)
- Essential Variable - QW407.1 = PWHT, QW407.4 = T Limits
- Supplimentry Essesntial Variable - QW407.2 = PWHT (T & T range)
- Supplimentry Essesntial Variable - QW409.1 = Heat input, QW409.4 = Current or polarity
- Supplimentry Essesntial Variable - QW410.9 = Multiple to single pass/side

ASME: remember that Group No is supplementary essential parameter. So the PQR, in case impact test is required needs to be repeated. A no is an essential parameter which is very frequently forgotten and is related to the chemical composition of the filler metal.
So in ASME parameters related to chemistry and material properties are P, group, A number and indirectly the F number

WPS for any specified material takes into consideration the chemical composition and mechanical properties which are validated by PQR.
Ammar Shaikh
yes, U can use any ASME, IS, EN or any group if P nos and Group nos matches in all respects.sridhar.
