ASME B107.59:2002 pdf download.SLUGGING AND STRIKING.

Hardness determination shall be made in accordance with ASTM 18 or equivalent.

52 Impact T.st

Sample wrenches shall be subjected to the impact lest in para. 5.2.1 cr 5.22, depending on the style of wrench. The struck block of the wrench shall not crack or chip. There shall be no bending of the shank or twisting of the box end. There shall be no cracks

evident on any portion of the wrench. Normal deformation of the struck face and the box end of the wrench is pennitted’

5.2.1 Slugging Wr.nch. Three sazrçles of the same styk and size slugging wrench shall be mourned on a hexagonal mandrel with the

middle wrench offset 30 deg with respect to the other wrenches. The hexagonal mandrel shall meet the requrements of ASME B107.6 or ASME B107.9M u applicable, Steel slums 0.25 in. (6.4 mm) thick shall be pLed under the heads of the two wrenches on the ends of

the mandrel, and the assembly clampled at each of these heads to a rigidly supported steel block weighing not less than 400 lb (182 kg). The drop weight shall have a sthkmg face hardness of not less than 45 H.RC or equivalent nor more than (it) HRC or equivalent and shall be dropped squarely onto the struck face of the middle wrench. The striking face diameter of the drop weight shall be

not less than 0.375 In. (9.53 mm) larger titan the struck face width of the wrench being struck.
