FOREWORD
This Indian Standard (First Revision) was adopted by the Bureau of Indian Standards, afler the draft finalized by theDiamond Core and Water Well Drilling Sectional Committee had been approved by the Mechanical EngineeringDivision Council.
This standard was first published in 1978. The experience gained in implementation of the standard necessitated thepresent revision.
In the preparation of this standard considerable assistance has been derived from the following standards:
1S0 10207:1991 Rock drilIing equipment — Rope threaded drill steel equipment for percussive drilling,nominal sizes 22 mm to 38 mm.
1S0 10208:1991 Rock drilling equipment — Left hand rope threads,
The composition of the Committee responsible for the formulation of this standard is given in Annex A.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2:1960‘Rules for rounding off numerical values (revised)’. The number of significant places retained in the rounded offvalue should be the same as that of the specified value in this standard

ROPE THREADED PERCUSSIVE LONG-HOLEDRILLING EQUIPMENTS — SPECIFICATION
(First Revision)
1 SCOPE
This standard covers the dimensions and requirementsfor percussive long-hole drMng equipment having ropetype threads.
2 REFERENCES
The following standards contain provisions, whichthrough reference in this text, constitute provisions of thisstandard. At the time of publication, the editions indi-cated were valid. All the standards are subject to revision.and parties to agreements based on this standard are en-couraged to investigate the possibility of applying the mostrecent editions of the standards indicated below:

3 TERMINOLOGY
For the purpose of this standard,tions shall apply.
the following defmi-
3.1 Nominal Size of Rods — The rod section shall beeither round or hexagonal. The width of hexagonal rodsacross the flats is equivalent to the corresponding size ofround rod that refers to the diameter of rod incase of roundrod and to the width across the flats of hexagonal sectionof hexagonal rods.
The hexagonal rods have a larger cross-sectioned areaand contain more material for a given nominal size,
3.2 Type of Rods
3.2.1 Shank Roa!r
Drill rods with an integral shank at one end and a threadat the other end.
3.2.2 Extension Roa!r
Ordinary extension rods have the same thread dmensionat both ends. They are available in two designs, malethreads at both ends or a female thread at one end and amale thread at the other end.
3.2.3 Light &tension Rodr
On lightextension rods, the rod section (usually hexago-nal) is smaller than the thread section, which is bumpedup before the thread is turned.

6 MATERIAL 7.4 The tips of the bits shall be free from pitting.
6.1 The rods and coupling sleeves shall be manufactured
from any high quality, high resistance to fatigue torsion,wear and impact resistant steel. The material used shallbe at the option of manufacturer who shall provide itscomposition if so desired by the purchaser. The shankshall be surface hardened.
6.2 The tips shall be manufactured from tungstencarbide conforming to Grade T or XT of IS 4005.
6.3 Carbon Content
Shank rod shall have high carbon content while exten-sion rods and couplings shall have low carbon content.They are hardened by high frequency surface hardeningor by carburization.
7 GENERAL REQUIREMENTS
7,1 Straightness
The rods shall be in a straight condition such thatwhen the body only is laid on a flat surface and rotated,no point on the line of contact is more than 3 mm abovethe surface for lengths up to 2 m and prorata for lengthsabove 2 m.
7.2 The threads of the drill rods shall be concentric withthe body.
7.3 The rods and the couplings shall be free from unduesurface decarburization, cracks and other defects.
7.5 The centre hole and threads of the components shallbe adequately protected against choking, erosion anddamage during transit and/or storage.
8 MARKING
8.1 Every component of the percussive long-hole drill-ing equipment shall be marked with the following:
a) Thread size;b) Shape and length of component;c) Bit gauge, if applicable; andd) Manufacturer’s name or trade-mark, month and
year of manufacture and type of steel shall beembossed at the collar of the shank.
NOTE — Instead of (a) to (c) the designation as specified in
the dimensional tables may be marked.
8.2 BIS Certification Marking
8.2.1 The rope threaded percussive long-hole drillingequipment may also be-marked with the Standard Mark.
8.2.2 The use of the Standard Mark is governed by theprovisions of the Bureau of Indian Standards Act, 1986
and the Rules and Regulations made thereunder. Thedetails of conditions under which a licence for the use ofthe Standard Mark may be granted to the manufacturersor producers maybe obtained from the Bureau of IndianStandards.
