This edition includes the following significant technical changes with respect to the previous edition:
a) definitions 3.11 and 3.20 were revised;
b) requirements for arc striking and stabilizing voltage rating have been added to the sequence of type tests (see 6.2);
c) the AC test voltage requirement for torches that utilize arc striking and stabilizing voltageshas been revised (see 7.5.2);
d) the test configuration of isolated circuits for torches that utilize arc striking and stabilizing voltages has been revised (see 7.5.2);
e) the metal tube used for the heating tests has additional allowable means of cooling methods (see 8.3.2 and 8.3.5);
f) for fume extraction torches, the instructions for use include additional information (see Clause 13, item i)).
