BRIEF HISTORY
The IS0 Recommendation R 538, Conventional Signs to be Used in Schemes for the Ins-
tallations of Pipeline Systems in Ships, was drawn up by Technical Committee ISO/TC 8, Ship-
building Details, the Secretariat of which is held by the Nederlands Normalisatie-instituut
(NNI).
Work on this question by the Technical Committee began in 1956 and led, in 1962, to the
adoption of a Draft IS0 Recommendation.
In March 1963, this Draft IS0 Recommendation (No. 562) 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:
Australia Greece Spain
Austria Israel Sweden
Belgium Italy
Switzerland
Chile Japan United Kingdom
Czechoslovakia Netherlands U.S.S.R.
Finland Norway Yugoslavia
France Poland
Germany Romania
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in January 1967, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 538
CONVENTIONAL SIGNS
TO BE USED IN SCHEMES FOR THE INSTALLATIONS
OF PIPELINE SYSTEMS IN SHIPS
INTRODUCTION
This IS0 Recommendation covers conventional signs to be used in schemes for installations
for ship pipelines. *
The symbols given in the Tables have been classified in the following manner:
1. General conventional signs
2. Pipes and pipe joints
3. Valves, gate valves, cocks and flaps
4. Control and regulation parts
5. Appliances
6. Fittings
7. Indicating and measuring instruments
The general conventional signs concern symbols representing principal parts and appliances.
The other signs are all derived from the general basic signs.
* Other IS0 Recommendations for conventional signs to be used in ships:

IS0 Recommendation No. 856.
ISO/R . . . . Conventional Signs to be used in Schemes for the Installations of Sanitary Systems in Ships, at present Draft
IS0 Recommendation No. 941.
