BRIEF HISTORY
The IS0 Recommendation R 265, Pipes and Fittings of Plastics Materials-Socket
Fittings with Spigot Ends for Domestic and Industrial Waste Pipes- Basic Dimensions:
Metric Series, was drawn up by the Technical Committee ISO/TC 5, Pipes and Fittings,
the Secretariat of which is held by the Association Suisse de Normalisation (SNV).
Work on this question by the Technical Committee began in 1957 and led, in 1959, to
the adoption of a Draft IS0 Recommendation.
In October 1960, this Draft IS0 Recommendation (No. 408) was circulated to all the
IS0 Member Bodies for enquiry. It was approved, subject to a few modifications of an
editorial nature, by the following Member Bodies :
Belgium Hungary Portugal
Chile India Romania
Czechoslovakia Iran Spain
France Israel Switzerland
Germany Italy U.S.S.R.
Greece Poland Yugoslavia
Four Member Bodies Opposed the approval of the Draft:
Denmark, Netherlands, Norway, Sweden
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in July 1962, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 265 July 1962
PIPES AND FITTINGS OF PLASTICS MATERIALS
SOCKET FITTINGS WITH SPIGOT ENDS
FOR DOMESTIC AND INDUSTRIAL WASTE PIPES
BASIC DIMENSIONS: METRIC SERIES
1. SCOPE
This IS0 Recommendation applies to plastics socket fittings with spigot ends for domestic and
industrial waste pipes, regardless of their method of manufacture (except fittings fabricated from
tubes) and composition. Its object is to specify the series of diameters to be used and the dimen-
sions which are common to all types of fittings.*
-4
It contains 46 types and sizes of fittings and should be used immediately as a guide to manu-
facturers and users and as a basis for specific standards. It may later be extended to other types
and sizes of fittings, when the development of plastics materials in the field of pipe systems makes
this necessary.
Extension to other types should be made by observing the principles laid down in this IS0
Recommendation.
2. DIAMETERS OF FITTINGS (SIZES)
The diameters of jointing should be the following:
32 - 50 - 75 - 110 - 160 mm.**
Fittings are designated by the diameters of their sockets. In the case of nipples, these are designated
by the diameters of the jointing surfaces, giving the male end first.
r'
3. ANGLES
For elbows and tees (branches), the angles should be 45", 67%" or 87%"
4. LAMNG LENGTH
When assembling a pipe system, the dimensions between the ends of the tubes which it is required
to join are
