The work of preparing International Standards is normally carried out through IS0 technical committees. Each m
9、ember body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the Internationa
10、l Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Inter- national Standard requires approval by at least 75% of the member bodies

13、 by a series of nesting hole sizes providing small clearances between the hole wall and the equipment, making it possible to use thin-walled casing tubes. The equipment specified in this International Standard should be considered a separate system in- tended to be applied in parallel with system A
14、(see IS0 3551) and sys- tem B (see IS0 3552): it is not interchangeable with these systems. iii INTERNATIONAL STANDARD 690 765 690 640 IS0 8866:1991(E) 490 12 590 14 490 12 370 16 Rotary core diamond drilling equipment - System C 1 Scope This International Standard specifies the material for and the
15、 dimensions of rotary core diamond drilling equipment, system C. NOTE 1 used. Cutting materials other than diamond may be It applies to - single- and double-tube core barrels, including diamond core bits, reaming shells, core lifters, core-liiter cases, core tubes (outer and inner) and he ads ; - dr
16、ill rods and couplings; - casing tubes and couplings. The casing tubes are not designed for drilling, and the casing string is only employed for casing-off the hole. The range of equipment covers diamond core drill- ing of holes from 35 mm to 112 mm in diameter (outer bit diameter) with the correspo
17、nding core di- ameters from 21 mm to 92 mm. Single- and double-tube core barrels provide a means of coring compact rocks (types M and DM core barrels), fissured and fractured rocks (types T and DT core barreis) and fractured and broken-down rocks (type DP core barrels). 2 Designation The designation
18、 of items complying with this Inter- national Standard comprises - the name of the item; - the letter(s) identifying the core barrel type (not applicable to drill rods and couplirig, casing tubes and casing couplings); - the nominal outside diameter of the item; - the letter C (denoting system C).
