Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 10097-2 was prepared by Technical Committee ISO/TC 82, Mining, Subcommittee
SC 6, Diamond core drilling equipment.
ISO 10097 consists of the following parts, under the general title Wireline diamond core drilling equipment —
System A:
 Part 1: Metric units
 Part 2: Inch units
Annex A of this part of ISO 10097 is for information only.

Introduction
ISO 10097 is intended for independent use as well as for use in combination with ISO 3551-2, which covers
equipment designed for conventional diamond drilling.
This International Standard covers equipment intended for application with diamond bits, but is should be
understood that bits may have other cutting materials.

of the following wireline drilling equipment for drilling holes of diameter 1,890 in to 3,790 in, yielding cores of
diameter 1,063 in to 2,500 in.
The equipment is illustrated in Figure 1 and comprises the following:
a) core bit;
b) reaming shell;
c) core lifter;
d) core lifter case;
e) outer tube;
f) inner tube;
g) drill rod (smooth pipe only).
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this part of ISO 10097. For dated references, subsequent amendments to, or revisions of, this publication do not
apply. However, parties to agreements based on this part of ISO 10097 are encouraged to investigate the possibility
of applying the most recent edition of the normative document indicated below. For undated references, the latest
edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid
International Standards.
ISO 3551-2:1992, Rotary core diamond drilling equipment — System A — Part 2: Inch units.
3 Designation
Items made in accordance with this part of ISO 10097 shall be designated by the identification letters WL and hole
dimensions A, B, N, H.

4 Materials
Materials used in the manufacture of the wireline drilling equipment specified in this part of ISO 10097 shall have the
minimum mechanical properties as specified in Table 1.

Other items Not specified
5 Dimensions and tolerances
5.1 General
All dimensions and tolerances are in inches unless otherwise stated and shall be in accordance with Tables 3 to 9
inclusive.
5.2 Conformity
In those industries where drilling depths are measured in metres, the rod lengths shall be 3,0 m, 1,5 m or 0,75 m.
When drilling in conformity with DCDMA and CDDA standards, the lengths of rods may be 10 ft, 5 ft or 2,5 ft.
5.3 Eccentricity
The eccentricity is defined as the distance between the centres of the outer and inner diameters and may not
exceed 10 % of the nominal wall thickness Q.
The eccentricity is calculated according to the formula:
QQ-max min
·100
2Q
nom
where Q and Q are measured values in the section.
max min
5.4 Straightness
When measured over the whole length of the tube by rolling against a straightedge, the maximum deviation shall not
be greater than:
 for drill rods 1 in 2 000;
 for core tubes 1 in 1 500.
5.5 Technical conditions
Tubes should be made seamless. Tube rolling technique and machining operations are optional.
Tube straightness is checked by rolling the tube on a horizontal or slightly inclined flat surface. When rolling, no
clearances shall be seen between the rod ends and the surface, nor between the middle of the rod (tube) and the
surface.
Hole drilling by wireline system A equipment shall be cased by system A casing as specified in ISO 3551-2.
