E X P L A N A T O R Y N O T E

The testing and performance of constant speed and variable speed internal combustionengines was earlier covered by the following Indian Standards:

IS : 1600-1960 Code for type testing of constant speed internal combustion engines for generalpurposes

IS : 1601-1960 Performance of constant speed internal combustion engines for general purposesIS : 1602-1960 Code for type testing of variable speed internal combustion engines for auto-

motive purposesIS : 1603-1960 Performance of variable speed internal combustion engines for automotive

purposes

These standards are originally issued in lS60. AS a result of implem~entation of thesestandards by the manufacturers of engines and testing laboratories, as also the operation of ISICertification Marking Scheme, these standards have now been extensively revised.

While IS : 1600 and IS : 1602 covered the codes for type testing of constant and variable speedengines respectively, the performance requirements of such engines were covered by IS : 1601 andlS : 1603 respectively. These standards are replaced by two sets of standards, one set covers themethods of testing of engines and the other covers the specification and performance requirementsof both constant speed and variable speed engines.

The standard covering methods of tests is being published in.following 12 parts of IS : lOCOo(each part covering a particular test method or informJatidn related to methods of tests:

lS : 10000 Methods of tests for internal combustion engines:Part I Glossary of terms relating to test methodsPart II Standard reference conditionsPart III Measurement for testing, units and limits of accuracyPart IV Declaratrons of power, efficiency, fuel coiwumption and lubricating oil consumptionPart V Preparation for tests and measurements for wearPart VI Recording of test resultsPart VII Governing tests for constant speed engines and selection of engines for use with

electrical generatorsPart VIII Performance testsPart IX Endurance testsPart X Tests for smoke levels, limits and corrections for smoke levels for variable speed

enginesPart Xl Information required with inquiry or order and information supplied by the manufac-

turer with the enginePart XII Test certificates

IS : 10000 ( Part I to XII ) will be complementhr! to specifications for performance requirementsof different types of engines covered by following standards:

IS : 10001 Specification for performance requirements or constant speed compression ignition

I( diesel > engines for general purposes (up to 20 W )

IS : lOG02 Specification for performance requirements for constant speed compression ignition( diesel) engines for general purposes (above 20 kW )

IS : lCOC3 Specification for performance requirements for variable speed compression ignition(diecel ) engines for automotive purposes

IS : 10004 Specification for performance pe@,uirements for variable’speed spark ignition engines yfo-r automotive purposes

Spark ignition engines for sprayers’ Specification for parfsrmancs

and similar application have been covered by IS : 7347-1974of small size spark ignition engines ‘.

Two-stroke spark ignition engines for automotive applications which were earlier covered byIS : 1603 will be covered by a separate specification.

IS:lOOOl-1981

This standard, that is, IS :.‘lOOOl has been evolved to help the user to quote the power, specificfuel consumption, lubricating oil consumption, etc, for ordering purpos~es. On the other hand, itwould be useful for the manufacturer to declare the performance of his engine. This standardwould be mainly applicable for agricultural pumpsets and other allied fields. The engines for thispurpose are expected to be rated for IS Rating A as there is bound to be occasional overloadingfor agricultural applications.

In this standard preferred power ratings according to R 20 series ( and R 20/2, R 2013 derivedseries ) have been included as it was found that ths engines presently manufactured tended to fallin line with this series. It is desirable that the manufacturers declare the power of their enginesfrom one of the preferred values.

~This standard specifies SFC values for engines which varies with the speed of the engine.While laying down these values the committee has taken cognizance of the capabilities of theengines manufactured in India at present. In view of the need-to conserve fuel and-to improve theefficiency of small diesel engines, the committee has desired that the SFC values should beimproved and has laid down the values that the engines are expected to meet after’ 1 January 1984.In arriving at these SFC values the committes has envisaged a 5 percent improvem-ent over thepresent SFC values and these values will be further reduced in case there is evidence that this canbe achieved.

IS : 10001 and IS : 10002 replace IS : 1691 for diesel engines up to 20 kW and above 20 kW,respectively. The category of spark ignition engines for general purposes is not being covered asthese types of engines are getting extinct.
