The number of tension test for ASTM A252

The number of tension test for ASTM A252

(OP)
ASTM A252 Para 16.1 state that one tension test shall be made for each 200 pipe. If those pipes (200 joints) made from two or more raw material/ coil (each coil has one heat number), it is permissible to perform only one tension test? Or it shall be made tension test for each raw material/ heat number?

You need five tension tests due to five different heats of skelp used for a lot.
