Revision of E1317-19 Standard Test Method for Flammability of Surface Finishes
Rationale
12.1.6 Type of pilot flame used, that is, impinging or nonimpinging.
However, there is no information on how to test with an impinging pilot flame. ISO 5658-2, which is a similar test (as explained in Note 1) provides a figure describing how to test with an impinging flame, which basically means that the pilot burner needs to be rotated slightly so as to impinge directly on the test specimen. However, this figure does not define the angle the pilot flame needs to be rotated.>Therefore, this ballot item recommends adding a section 11.1.10.1 explaining that an impinging pilot flame is one on which the pilot flame has been rotated slightly to impinge directly on the test specimen. No other change of text is being proposed. The procedure section is shown for context.
This ballot item also suggests that Figure A1.2 be rotated so that a vertical test specimen is shown vertically and not horizontally (See at end
