Full title and description

ISO 9943:2009 — Shipbuilding — Ventilation and air‑treatment of galleys and pantries with cooking appliances. This International Standard gives design requirements and general considerations for ventilation and air‑treatment systems serving galleys and pantries that contain cooking appliances on merchant seagoing ships when such systems are specified by the shipowner.

Abstract

ISO 9943:2009 specifies principles for removing heat, moisture, fumes, grease and odours produced by cooking appliances and for supplying appropriate make‑up air to galleys and pantries on board merchant ships. It covers normal operating conditions (excluding extremely cold or hot climates), defines the kinds of pantries and appliances in scope, and notes that compliance with applicable statutory requirements, class rules and national regulations must also be ensured.

General information

• Status: Published / Valid.
• Publication date: 2009 (published April–May 2009).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 47.020.90 (Marine ventilation, air conditioning and heating systems).
• Edition / version: Edition 2 (2009).
• Number of pages: 12 pages.

Scope

The standard applies to the design of ventilation and air‑treatment systems for shipboard galleys and pantries that include cooking appliances (beyond small electrical warmers and coffee urns). It addresses extraction, make‑up air, general air‑treatment, and the environmental conditions for which the requirements are intended — normal seagoing conditions excluding extreme climates. It is intended for merchant seagoing ships and applies when such ventilation is specified by the shipowner; it does not replace mandatory statutory or class requirements.

Key topics and requirements

• Design principles for removal of heat, moisture and combustion products from cooking areas.
• Requirements for localized extraction (hoods and canopy systems) above cooking appliances.
• Provision and sizing of make‑up (supply) air to maintain pressure and ventilation rates.
• Handling of grease, smoke and odours — ducting, filters and grease‑collection considerations.
• Materials, routing and termination of ducts appropriate for marine environment and fire safety.
• Noise, access for maintenance and serviceability of ventilation equipment.
• Coordination with ship services, energy sources and statutory/safety regulations (including fire safety and smoke control).
• Considerations for normal climatic ranges and notes on limitations in extreme hot or cold conditions.

Typical use and users

Used by ship designers, naval architects, shipbuilders, marine HVAC engineers, shipowners specifying outfitting requirements, classification society surveyors, marine equipment manufacturers (hoods, fans, filters, ductwork), and maritime safety/inspection authorities. It is referenced when specifying galley ventilation systems and during design reviews, procurement and installation acceptance.

Related standards

Relevant documents in the marine HVAC and shipbuilding area include the earlier edition ISO 9943:1991 and other ship ventilation/air‑conditioning design standards developed under ISO/TC 8/SC 3, for example standards addressing accommodation space ventilation, engine‑room ventilation and ventilation of cargo spaces. National adoptions and regional equivalents may also exist; users should check applicable class rules and statutory requirements for the ship concerned.

FAQ

Q: What is this standard?

A: ISO 9943:2009 is an International Standard that specifies design requirements and general considerations for the ventilation and air‑treatment of galleys and pantries containing cooking appliances on merchant seagoing ships.

Q: What does it cover?

A: It covers principles for extraction of heat, moisture, smoke, grease and odours from cooking areas, requirements for hoods and ducting, make‑up air provisions, maintenance and serviceability considerations, and limitations for extremely hot or cold climates. It also reminds users to ensure compliance with statutory and class requirements.

Q: Who typically uses it?

A: Ship designers, naval architects, marine HVAC engineers, shipowners, classification societies, equipment manufacturers and maritime inspectors use the standard when designing, specifying or accepting galley ventilation systems.

Q: Is it current or superseded?

A: This document was published in 2009 (2nd edition). It is the 2009 edition that replaced the 1991 edition. Users should verify the current status with their national standards body or ISO for any later revisions or replacements before assuming applicability.

Q: Is it part of a series?

A: It belongs to the body of shipbuilding and marine ventilation standards (ICS 47.020.90) developed under ISO/TC 8/SC 3. Related ISO documents address ventilation of accommodation spaces, engine rooms, wheelhouses and cargo spaces; ISO 9943 is the specific standard for galleys and pantries with cooking appliances.
