Full title and description
ISO 3604:1976 — Fittings for unplasticized polyvinyl chloride (PVC) pressure pipes with elastic sealing ring type joints — Pressure test for leakproofness under conditions of external hydraulic pressure. Russian title (approximate translation): «Фитинги для напорных труб из непластифицированного поливинилхлорида (ПВХ) с уплотнительными кольцами — Испытание на герметичность при воздействии внешнего гидравлического давления».
Abstract
Specifies a test method and apparatus to check the leakproofness of an assembled elastic-seal-ring joint in unplasticized PVC pressure pipe systems when subjected to external hydraulic pressure greater than the atmospheric pressure inside the pipe. The standard requires testing at two pressure-difference levels (0.01 MPa and 0.08 MPa) and requires no leakage to occur.
General information
- Status: Withdrawn / Cancelled.
- Publication date: November 1976 (Edition 1).
- Publisher: International Organization for Standardization (ISO).
- ICS / categories: 23.040.45 — Plastics fittings.
- Edition / version: Edition 1 (1976).
- Number of pages: 2 pages (short procedural standard).
Scope
This standard defines the apparatus and procedure for a pressure test to verify the leakproofness of assembled elastic sealing‑ring joints used in fittings for unplasticized PVC (uPVC) pressure pipe systems when subjected to external hydraulic pressure. The test is performed at two differential pressure levels (0.01 MPa and 0.08 MPa) and requires that no leakage occur from the joint under those conditions. It is limited to the leakproofness check for assembled joints and does not cover other performance characteristics (e.g., long‑term durability, chemical resistance).
Key topics and requirements
- Defined test apparatus and specimen assembly for elastic sealing‑ring joints in uPVC pressure‑pipe fittings.
- Two prescribed external hydraulic pressure‑difference levels for testing: 0.01 MPa and 0.08 MPa.
- Acceptance criterion: no leakage from the assembled joint under the specified test conditions.
- Application limited to leakproofness under external hydraulic pressure — does not replace more recent, comprehensive test suites for thermoplastics piping systems.
- Produced under ISO/TC 138 (Plastics piping systems), subcommittee SC 2.
Typical use and users
Used historically by manufacturers of uPVC fittings, testing laboratories, conformity assessment bodies, standards developers, and procurement/specification writers to verify basic leakproofness of elastic‑seal‑ring joints under external hydraulic pressure. As the standard is withdrawn, current users typically refer to newer ISO or regional standards for comprehensive testing and product specification.
Related standards
ISO 3604:1976 is one of a set of short ISO standards from the 1970s on PVC pipes and fittings; it has been withdrawn and superseded in practice by more recent and broader standards covering thermoplastics piping systems and pressure testing (for example, ISO 1167 series for resistance to internal pressure, ISO 12162 for materials classification, and later parts/standards for fittings and dimensions). Related withdrawn contemporaries include ISO 3606:1976 (PVC pipe tolerances). Users should consult newer ISO and EN standards for current test methods.

FAQ
Q: What is this standard?
A: ISO 3604:1976 is a short international standard that specified a pressure test method and apparatus to check the leakproofness of assembled elastic sealing‑ring joints in fittings for unplasticized PVC pressure pipes. It was published by ISO in November 1976.
Q: What does it cover?
A: It covers only the specific pressure test for leakproofness under external hydraulic pressure (two differential pressures: 0.01 MPa and 0.08 MPa) and the requirement that no leakage occur. It does not cover broader performance properties or long‑term behaviour.
Q: Who typically uses it?
A: Historically, manufacturers of uPVC fittings, independent test laboratories, conformity assessment bodies and standards writers used this procedure to check joint leakproofness. Today, users normally refer to more recent standards for specification and testing.
Q: Is it current or superseded?
A: ISO 3604:1976 has been withdrawn (cancelled). It is not a current active ISO test method; newer ISO and regional standards have taken over the testing and specification roles for thermoplastics piping systems. EVS and ISO lifecycle records indicate withdrawal of the 1976 edition.
Q: Is it part of a series?
A: It was part of ISO work produced by ISO/TC 138 (Plastics piping systems) and related to other short ISO standards from the 1970s addressing PVC pipes and fittings; however, it is a standalone test method rather than a numbered multipart series. Later, more comprehensive multipart standards for thermoplastics piping replaced many of these separate items.
Q: What are the key keywords?
A: Key keywords include: leakproofness, pressure test, elastic sealing ring, uPVC fittings, external hydraulic pressure, ISO 3604, withdrawn standard.
