16、size shall be selected from eachlot identified by heat. When the material cannot be identifiedby melt or heat, five separate samples from each lot shall beselected. Samples may be taken from bend test specimensrepresentative of the lot. The chemical compositions thusdetermined shall conform to the e

In case the materialcannot be identified by melt, a lot shall consist of not more than25 tons (22.7 Mg) of floor plates of the same thickness.6.2 Bend Test:6.2.1 From each lot, two longitudinal cold bend testspecimens, 18 in. long by 2 in. wide (457 by 51 mm), shall beselected. When a lot c

19、annot be identified by melt, fivelongitudinal cold bend test specimens, 18 in. long by 2 in.wide, shall be selected.

Thesample shall be tested in the as mill annealed condition.6.3.3 The magnetic permeability shall not exceed 1.20 whenthe magnetic permeability indicator of MIL-I-17214 is used. Incase of failure of the specimen to comply, this shall be causefor rejection of the lot represe

The stainlesssteel floor plates shall have raised figures on one surface of thefloor plate.The reverse side

25、 shall be flat, except that the portionbelow the raised figure on plates having a nominal weightbelow 5.25 lb/ft2(25.5 kg/m2) may be hollow.7.2 Plates shall not exceed the respective weight specified inTable 1 by more than 8 %.7.3 Variations over the specified width and length shall notexceed the am

26、ounts permitted in Table 3. Variations under thespecified width and length shall not exceed14 in. (6.3 mm).7.4 The thickness of the floor plates shall conform to therequirements of Table 1 and shall be measured at least38 in.(9.5 mm) from the edge of the plate exclusive of the raisedfigures.7.5 Camb
