Foreword

IS0 (the international Organization for Standardization) is a worldwide federation of

national standards bodies (IS0 member bodies). The work of preparing International

Standards is normally carried out through IS0 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, govern-

mental and non-governmental, in liaison with ISO, also take part in the work. IS0

collaborates closely with the International Electrotechnical Commission (IEC) on all

matters of electrotechnical standardization.

The main task of IS0 technical committees is to prepare International Standards. In ex-

ceptional circumstances a technical committee may propose the publication of a
Technical Report of one of the following types:
type 1, when the required support cannot be obtained for the publication of an
International Standard, despite repeated efforts;
type 2, when the subject is still under technical development or where for any

other reason there is the future but not immediate possibility of an agreement on an

International Standard;
type 3, when a technical committee has collected data of a different kind from

that which is normally published as an International Standard (“state of the art”, for

example).

Technical Reports of types 1 and 2 are subject to review within three years of publica-

tion, to decide whether they can be transformed into International Standards.

Technical Reports of type 3 do not necessarily have to be reviewed until the data they

provide are considered to be no longer valid or useful.

ISO/TR 8865, which is a Technical Report of type 3, was prepared by Technical Com-

mittee ISO/TC 82, M/‘nlng, Sub-Committee SC 2, Components of coalface machinery
using high-tensile round link chains.

International Standard IS0 5613 : 1984 covering drive sprocket assemblies for mining

chain conveyors specifies requirements for a range of sprocket assemblies for use with

twin outboard assemblies. These assemblies incorporate sprocket rings designed to

accept chains complying with IS0 610, shackle type connectors complying with
IS0 1082 and scraper bars complying with IS0 5612.
The dimensions of the component parts of the sprocket assembly are laid down in

IS0 5613 and these dimensions have to be verified in order to check compliance with

the standard. It is stated that the methods to be used for the verification of the dimen-

sions shall be agreed between the purchaser and the manufacturer (IS0 5613 : 1984,

4.3). A number of the dimensions specified, in particular those relating to the tooth

profile of the sprocket, cannot be measured by the direct application of conventional

measuring instruments and it was decided to give some guidance on the special techni-

ques involved.

The member bodies participating in the work of lSO/TC 82/SC 2 studied the problem

and it was found that a number of varying methods and instruments were used, all

equally satisfactory if the appropriate dimensions were controlled to ensure com-

patibility with the other components of the chain assembly.
The committee therefore came to the conclusion that no one method or instrument

need be adopted as the “standard” method but guidance would be helpful on certain

general principles and essential features of the checking gauges. This document is

therefore published in the form of a Technical Report rather than an International

Standard.
