Full title and description

Air-conditioning and ventilation of dry provision rooms on board ships — Design conditions and basis of calculations. This International Standard specifies design conditions and the basis for calculating ventilation and air‑conditioning requirements for dry provision (dry stores) rooms on seagoing merchant ships (not intended for extremely hot climates).

Abstract

ISO 9099:1987 sets out recommended environmental design conditions and the calculation basis for ventilation and air‑conditioning of dry provision rooms on board ships, referencing ISO 7547 for underlying principles. The standard was prepared by ISO/TC 8/SC 3 and applies to seagoing merchant ships under normal climatic conditions.

Scope

Applies to the air‑conditioning and mechanical ventilation design of dry provision rooms (dry stores) on board seagoing merchant ships for normal operational climates, excluding extreme hot‑climate conditions. The document provides the design environmental conditions and the calculation basis to size ventilation and air‑conditioning systems for these spaces and is intended to be used alongside ISO 7547.

Key topics and requirements

• Specified indoor design conditions (temperature/humidity targets) for dry provision rooms under normal shipboard service conditions.
• Basis of calculation for ventilation rates and air‑conditioning loads for dry stores.
• Guidance on application limits (not intended for extremely hot climates).
• Reference to ISO 7547 for underlying principles and additional design data.
• Short-form technical specification intended for use by ship HVAC designers and naval architects.

Typical use and users

Used by ship designers, marine HVAC engineers, naval architects, shipyards, marine consultants, and standards offices when specifying or verifying ventilation and air‑conditioning for dry provision rooms on merchant vessels. Also used by regulators and classification societies as a reference for acceptable design practice prior to its withdrawal.

Related standards

ISO 9099:1987 has been withdrawn and a newer related standard is ISO 7547 (2022 edition), which provides updated guidance for ventilation and air‑conditioning on ships and is listed as the replacement. National/adopted equivalents and identical versions have included DIN ISO 9099 (German adoption) and several national catalog listings.

FAQ

Q: What is this standard?

A: ISO 9099:1987 is an International Standard that specified design conditions and calculation bases for air‑conditioning and ventilation of dry provision (dry stores) rooms on board seagoing merchant ships.

Q: What does it cover?

A: It covers recommended indoor environmental conditions (temperature and humidity targets where applicable), ventilation rates, and the calculation methodology used to size ventilation and air‑conditioning systems for dry provision rooms under normal climatic conditions (excluding extremely hot climates). The standard references ISO 7547 for additional data and principles.

Q: Who typically uses it?

A: Marine HVAC designers, naval architects, shipyards, classification societies, maritime regulators, and consultants involved in the design, verification, or regulation of shipboard ventilation and air‑conditioning systems.

Q: Is it current or superseded?

A: ISO 9099:1987 is withdrawn and has been superseded by a more recent standard (ISO 7547:2022). It is not the current reference document for new designs. Consult ISO 7547:2022 for current guidance.

Q: Is it part of a series?

A: It is related to other ISO shipboard HVAC documents and specifically references ISO 7547; national adoptions (for example DIN ISO 9099) were issued where the text was adopted identically. ISO/TC 8/SC 3 is the technical committee responsible for the subject area.

Q: What are the key keywords?

A: Dry provision rooms, dry stores, ship ventilation, ship air‑conditioning, marine HVAC, design conditions, calculation basis, ISO 7547, maritime standards.
