29、al Mechanical Engineering Standards Policy Committee. It is identical with ISO3551-2:1192 Rotary core diamond drilling equipment System A Part2:Inch units, which was prepared by Technical Committee ISO/TC82/SC6 Diamond core drilling equipment, of the International Organization for Standardization (I
30、SO) and in the development of which the United Kingdom played an active part. To a large extent this Part of BS4019 has been based on BS4019-1:1974, which first was issued in1966 and subsequently revised and converted into SI units by the UK in1974 in cooperation with Canada and the USA and supporte
31、d by Australia and South Africa and based on a proposal to ISO for an International Standard. This Part of BS4019, together with BS4019-3:1993, supersedes BS4019-1:1974 which is withdrawn. In this Part of BS4019 all dimensions are in inch units and the purpose of this Part is to provide, on an inter
32、national basis, the dimensional interchangeability in essential rotary core drilling fittings. These fittings are designed specifically for drilling with water as the circulating medium and are not necessarily suitable for use with air or mud as the circulating media. It is proposed to produce other
33、 Parts of this standard to cover equipment for use with air flush and wire-line, but it is not intended to publish British Standards on System B or System C. BS4019 comprises the following Parts: Part 3: Specification for system A. Metric units; Part 4: Specification for system A. Inch units. NOTETh
34、e title of the ISO standard is Rotary core diamond drilling equipment. However, the use of other cutting materials is permitted (see note to clause1). The Technical Committee has reviewed the provisions of ISO5864 and API7, to which normative reference is made in the text, and has decided that they
35、are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from le
36、gal obligations.

38、s the nomenclature and lays down the leading dimensions to ensure interchangeability within the limits of System A of the following equipment: a) drill rods and couplings; b) casings, casing couplings, casing bits, casing shoes, drive shoes and casing reaming shells; c) core barrels, core bits, core
39、 lifters and reaming shells. It specifies the characteristics of a range of equipment for drilling holes having diameters from1.18 in to7.88 in and yielding cores having diameters from0.73 in to6.5 in. NOTEThe title of this part of ISO3551 specifies diamond core drilling, but it is also possible to
40、use other cutting materials. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO3551. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to ag
41、reements based on this part of ISO3551 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO263:1973, ISO inch screw threads General plan and selec

43、manufactured in accordance with this part of ISO3551 shall be designated by its number followed by the symbols as listed in Table 1. 4 Materials Materials used in the manufacture of the equipment specified in this part of ISO3551 shall have the mechanical properties specified in Table 2, though for
44、special purposes other materials may be used by agreement between manufacturer and purchaser. The method by which the mechanical properties of tubes are obtained is left to the manufacturer. 5 Dimensions and tolerances 5.1 Dimensions All dimensions and tolerances shall be in accordance with Table 4
45、to Table 57. All dimensions given in this part of ISO3551, unless otherwise stated, are in inches (see Introduction). NOTE 1In System A, maximum and minimum values are included for all dimensions. NOTE 2All these items have a right-hand thread. Where a left-hand thread is necessary, it is stipulated
46、 for each individual case in the footnotes to the figure or to the corresponding table. NOTE 3The radius (or chamfer) of the thread crest and the radius in thread root corners are left to the manufacturers (determined by national standards of manufacturers countries). 5.2 Conformity When drilling in
47、 conformity with American Diamond Core Drill Manufacturers Association (DCDMA) and Canadian Diamond Drilling Association (CDDA) standards, the lengths of rods and casings shall be120in,60in or30in, but in those industries where drilling depths are measured in metres, the rod and casing lengths may b
48、e3m,1,5m or0,75m. 5.3 Eccentricity The eccentricity is defined as the distance between the centres of the outside and inside diameters andshall not exceed10% of the nominal wall thickness Q. The eccentricity is calculated according to the formulawhere Q maxand Q minare values of the wall thickness measured in the same section. 5.4 Straightness When measured over the whole length of the tube by rolling against a straightedge, the maximum deviation shall not be greater than1 in1200.
