(3) Where specimens are to be removed from the body of the casting, a steel, thermal buIkr pad Ii X 1: X at least 3 shall be joined to the casting surface by a partial penetration weld completely sealing the bufkred surface prior to the heat treatment process. The test specimens shall be removed froni the casting in a location adjacent to the center third of the bufkr pad. They shall be located aLa minimum distance of 1/2 in. (13 mm) from the buffered surface and 1/, from the other heat treated surfaces.
(4) Where specimens arc to be removed from the body of the casting. thermal insulation or other thermal harriers shall be used during the heat treatment process adjacent to the casting edge where specimens are to he removed. It shall be demonstrated that the cooling rate of the test specimen is no faster than that of specimens taken by the method described in (h)f I) above. This information shall be included in the test reports.
(5) Where castings are cast or machined to essentially the tinishe*i product configuration prior to heat treatment. the test specimens shall be removed from a casting prolongation or othcr stock on the product at a location below the nearest heat treated surface indicatcd on the order. The specimens shall be located with their longitudinal axes a distance below the nearest heat treated surface equivalent to at least the greatest distance that the indicated high tensile stress surface will be from the nearest heat treated surface and with their midlcngth a minimum of twice this distance from a second heat treated surface. In any case. the longitudinal axes of the test specimens shall be no nearer than 1/ in. (6 mm) to a heat treated surface and the midlengih shall be at least 11/2 in. (38 mm) from a second heal treated surface. The component manufacturer shall specify the surfaces of the finished product subjected to high tensile stress in service.

MATERIAL
NE-2310 MATFRIAI. TO 1W IMPACT TESTFI)
NE-231I Niaterial for Which Impact Testing Is Required
(a) Pressure retaining material shall be impact tested in accordance with the requirements of NE-2330. except that impact testing of materials described in (I through (9) below is not a requirement of this Subsection, provided the requirements of NE-2121(c) are met.
NE-2332.3 Bolting Material. The drop weight test is not applicable to bolting materials. For bolting material. including nuts. studs, and boils, a Charpy V-notch lest shall be performed. Optionally, the test may be performed at the Lowest Service Metal Temperature, or at a temperature 30°F(17°C) or more below the Lowest Service Metal TemperatLire.
(a) When tested at the Lowest Service Metal Temperature, lateral expansion and absorbed energy values shall be determined, and all three specimens shall meet the requirements of Table NE-2332.3(a)-l.
(h) When tested at 30°F ( lC) or more below the Lowest Service Metal Temperature, lateral expansion and absorbed energy values shall he determined, and all three specimens shall meet the requirements of Table NE-
2332.3(b)-I.

The impact test results of the three specimens. collectively and singly, shall meet the respective requirements of Table NE-2333.I-I.
NE-2333.2 Bolting Material. For bolting material. including nuts, studs, and bolts, a Charpy V-notch test shall be performed, The lest shall be performed at or below (he Lowest Service Metal Temperature, and all three spediiiens shall meet the requirements of Table NE-2332.3(a)- 1.
M-234O NUMBER OF IMPACT TESTS REQLJIRFA)
NE-2341 Plates
One test shall be made from each plate as heal treated. Where plates are furnished in the nonheat-treated condition and qualified by heat treated lest specimens. one lest shall be made for each plate as-rolled. The terni as-rolled refers to the plate rolled from a slab or directly from an ingot. not to its heat treated condition.
