6.4 General forms and dimensions. When material is ordered in the form of slabs, bars, discs, or rods, it is to
be understood that these terms refer merely to the general form and dimensions of the material, and do not have any
technical significance as to the methods of manufacture.
6.5 Sampling procedure.
6.5.1 Drilling procedure. The drilling for chemical analysis should be made with a special nonferrous drill in a
clean location (used only for that purpose). The drilling bits should be kept clean of dirt, grit, and other foreign
matter; kept properly sharpened; and used only for sampling purposes. After each use, the drilling bit should be
immersed in a degreasing solvent and wiped dry with a clean rag. The drilling bits, when not in use, should be
stored in an inhibited lubricating oil. The inhibited lubricating oil should be kept in a covered glass container
provided with an air vent. The drilling bits should be wiped dry with a clean rag prior to use. Samples should be
taken with a dry drill. If automatic power drilling equipment is available, a solid tungsten carbide or Tantung twist
drill bit about ½ inch (12.7 millimeters) in diameter is suitable. Where a hand-held power drill is used, the samples
should be taken by drilling with a solid tungsten carbide or Tantung twist drill bit about ¼ inch (6.35 millimeters) in
diameter. A smaller drill bit may be used where the size of the anode does not permit using the specified diameters.
The drills may be used at high speeds and feeds.
6.5.2 Machining procedure. The chips for chemical analysis should be made with a special nonferrous tool in a
place which has been cleaned for that specific purpose. Instructions specified in 6.5.1 apply to the use and care of
this tool.
6.6 Sub-contracted material and parts. The packaging or preparation for delivery of requirements of referenced
documents listed in section 2 do not apply when material and parts are acquired by the contractor for incorporation
into the equipment and lose their separate identity when the equipment is shipped.
