(e) Telltale Holes. Telltale holes may be used to providesome positive indication when the thickness has been reduced to a dangerous degree. Telltale holes shall not be used in vessels that are to contain lethal substances [see UW-2(a)], except as permitted by ULW-76 for vent holes in layered construction. When telltale holes are provided, they shall have a diameter of 1/16 in. to 3/16 in. (1.5 mm to 5 mm)and have a depth not less than 80% of the thickness required for a seamless shell of like dimensions. These holes shall be provided in the opposite surface to that where deterioration is expected. [For telltale holes in clad or lined vessels, see UCL-25(b).]

十分感谢大家的回复，本人又仔细看了看，看来国内标准借鉴比较多，索性给ASME点钱，编入我国标准得了。
