1/ Following stand test, the above inspection standards shall apply in addition to the acceptance standard of Table II.

2/ If it is impossible to determine source of the stain by thorough engineering and laboratory tests, excluding dissection, a stain of 1 inch maximum diameter or equivalent area is allowable, except self-sealing fuel cells, provided there is not greater than one such stain per 150 square feet of cell area.
