This International Standard is intended to supplement the IMO Code for Ships Operating in Polar Waters and the IACS UR "I", Requirements Concerning Polar Class. Although the application of this International Standard is primarily concerned only for ships operating in polar regions, some of the design considerations and planning might need to be implemented during construction or in a shipyard environment.

IEC PAS 80005-3:2014(E) describes low voltage shore connection (LVSC) systems, on board the ship and on shore, to supply the ship with electrical power from shore.

ISO 28521:2009 specifies pipe cleaning and cleaning levels of hydraulic oil pipe systems. The cleaning of pipes and components in hydraulic oil pipe systems is essential for the trouble-free operation of hydraulic systems. It indicates methods and equipment for the practical execution of the cleaning of specific parts of hydraulic systems with appurtenant components. The purpose of the cleaning process is to remove installation dirt and to check that the piping and hydraulic system have been adequately cleaned. The cleaning process of a system is considered a “washing through” process when the Reynolds number,Re, u 3 000, and a flushing process when Re W 3 000. The Reynolds number is an indicator of whether a fluid flow is considered laminar or turbulent. ISO 28521:2009 presupposes that the pipe sections of the hydraulic system have been cleaned partly by pickling and partly by mechanical cleaning. It is furthermore assumed that both dynamic and static components from system suppliers are adequately clean when delivered. The specifications given in ISO 28521:2009 are supplementary to, and not a replacement for, the guidelines specified by the various manufacturers. The manufacturer's guidelines, where available, take precedence.

ISO 9943:2009 specifies the design requirements and general considerations for the ventilation and air-treatment of galleys and pantries with cooking appliances on board merchant seagoing ships, when such ventilation and air-treatment is specified by the shipowner. It applies for normal conditions in all waters except those encountered in extremely cold or hot climates. For the purposes of ISO 9943:2009, pantries with cooking appliances, referred to above, are those which contain appliances consuming more than the small amount of electrical power needed for coffee urns, hot-plates for keeping food warm, electric water boilers, etc. Users of ISO 9943:2009 should note that, while observing its requirements, they should at the same time ensure compliance with such statutory requirements, rules and regulations as may be applicable to the individual ship concerned.

ISO 28522:2009 provides guidance for assembly and flushing of hydraulic oil systems. The aim of the flushing process is twofold: to remove dirt from the erection, installation, and to demonstrate that the pipes and the system as a whole are sufficiently clean. ISO 28522:2009 gives guidelines to ensure that pipes and components are mounted and tested correctly. It also gives practical conditions for the flushing oil and filter.

ISO 28523:2009 specifies methods for dynamic and static extraction of fluid samples from lubricating and hydraulic oil systems. A correct execution of the sampling is essential when analysing fluids from lubricating and hydraulic oil systems. In order to achieve reliable and comparable analysis results, the sampling must be performed under defined conditions and operating environment. When the system has reached its operating temperature, a representative sample is extracted from where the fluid is in a turbulent flow condition. This method is called dynamic sampling. If this is not possible, the sample can be extracted from the system tank. This method is called static sampling. ISO 28523:2009 specifies methods for both dynamic and static sampling in connection with collection in bottles. For extraction of samples through a filtration kit for comparison with “master slides”, reference is made to the manuals from the suppliers of such equipment.

ISO 28520:2009 provides guidance for flushing of lubricating oil systems, and grading of the resultant cleanliness. The flushing process is twofold: to remove dirt from the erection and installation, and to demonstrate that the pipes and the system as a whole is sufficiently clean. Crankcase and, where applicable, gearbox etc. are cleaned separately before flushing, and requirements relating to this are also specified in ISO 28520:2009. Similar considerations apply to the system tank and other components of the system. For the purposes of ISO 28520:2009, the cleaning process is considered as “washing through” when the Reynolds is equal to or less than 3 000 and “flushing” when the Reynolds number is equal to or greater than 3 000. Where available, any original equipment manufacturer requirements for flushing take precedence over the requirements outlined in ISO 28520:2009.

ISO 14726:2008 specifies main colours and additional colours for identifying piping systems in accordance with the content or function on board ships and marine structures. These colours can also be used for piping systems on drawings and diagrams. ISO 14726:2008 does not apply to piping systems for medical gases, industrial gases and cargo. ISO 14726:2008 can also be used for land installations.

ISO 19922:2005 specifies requirements on a test bench for determining the fire resistance of metallic pipeline components containing a resilient or elastomeric material, in particular by tests according to ISO 19921.

ISO 19921:2005 specifies test procedures for determining the fire resistance of metallic valves, pipe couplings, and similar pipe components which contain a resilient or elastomeric seal and which are used in ship engineering systems. The purpose of ISO 19921:2005 is to determine whether, after the period of fire testing on a test bench which fulfils the requirements of ISO 19922, pipeline components remain tight, and without any failure which could affect their function, even when subjected to proof pressure.
