Full title and description

ISO 3500:1976 — Seamless steel CO2 cylinders for fixed fire‑fighting installations on ships. The 1976 international standard specifies principal external dimensions, accessories, filling ratio and marking for seamless steel carbon dioxide cylinders intended for fixed shipboard fire‑fighting installations; a Russian-language entry for the standard is available in ISO’s catalogue.

Abstract

Defines requirements to ensure interchangeability and safe use of seamless steel CO2 cylinders fitted into fixed fire‑fighting systems on cargo and passenger ships, salvage vessels, heavy‑lift vessels, tug‑barge combinations and offshore platforms that can be serviced in port or dry dock. Topics include external dimensions, accessories (valves and siphon tubes), allowable filling mass (filling ratio), tare definitions and marking.

• ICS / categories: 13.220.10 (Fire‑fighting); 47.020.99 (Shipbuilding / marine structures).
• Edition / version: Edition 1 (1976).
• Number of pages: 2 pages (short technical specification).

Scope

This standard covers the principal external dimensions, prescribed accessories (such as collars, valves and siphon tubes), admissible filling ratios (mass of CO2 when filled), tare definitions and marking requirements for seamless steel CO2 cylinders intended specifically for fixed fire‑fighting installations fitted to ships and certain offshore units. Its purpose is to facilitate interchangeability and safe handling of these cylinders within shipboard systems.

Key topics and requirements

• Specification of principal external dimensions to ensure mechanical interchangeability and fitting into shipboard mounting and manifold systems.
• Required accessories and fittings (collar/guard, valve types, tube‑siphon) appropriate for shipboard fixed installations.
• Admissible filling ratio and definitions for tare and filled mass to standardize capacity and charging procedures.
• Marking and identification requirements for safe servicing, inspection and interchange.
• Compatibility and interchangeability considerations for maritime service environments.

Typical use and users

Used historically by shipboard fire‑protection system designers, shipbuilders, manufacturers of seamless steel CO2 cylinders, maritime safety engineers, classification societies, flag and port State inspectors, and ship operators for specifying or verifying cylinder dimensions, fittings and marking for fixed CO2 extinguishing installations. After withdrawal, users are directed to later revisions for current requirements.

Related standards

ISO 3500:1976 was subsequently revised — notably by ISO 3500:1990 and the later consolidated edition ISO 3500:2005 (Gas cylinders — Seamless steel CO2 cylinders for fixed fire‑fighting installations on ships), which contains expanded and updated requirements and remained confirmed in later reviews. The standard was developed under ISO/TC 58 (Gas cylinders). Users should consult the later ISO 3500 editions for the current, authoritative requirements.

FAQ

Q: What is this standard?

A: ISO 3500:1976 is an international standard that specified dimensions, accessories, filling ratios and marking for seamless steel CO2 cylinders used in fixed shipboard fire‑fighting installations. It is the first (1976) edition of ISO 3500.

Q: What does it cover?

A: It covers principal external dimensions, required accessories (collar, valve, siphon tube), definitions of tare and admissible filling mass, and marking to ensure safe interchangeability and servicing of shipboard CO2 cylinders.

Q: Who typically uses it?

A: Shipbuilders, designers of fixed fire‑fighting systems, cylinder manufacturers, classification societies, maritime inspectors and ship operators—professionals involved in specifying, installing, servicing and inspecting shipboard CO2 systems.

Q: Is it current or superseded?

A: ISO 3500:1976 is withdrawn (superseded). Later revisions include ISO 3500:1990 and ISO 3500:2005; the 2005 edition is the consolidated, later authoritative text and should be consulted for current requirements.

Q: Is it part of a series?

A: Yes — it belongs to the family of ISO standards on gas cylinders and maritime fire‑fighting equipment produced under ISO/TC 58. The ISO 3500 number has later editions (1990, 2005) updating the original 1976 text.

Q: What are the key keywords?

A: CO2 cylinder; seamless steel; shipboard fixed extinguishing system; filling ratio; marking; valve; siphon tube; interchangeability.
