21、rd seagoing merchant ships for all conditions except those encountered in extremely cold or hot climates (i.e. with lower or higher conditions than those stated in 4.2 and 4.3). Annex A provides guidance and details of good practice in the design of ventilation and air-conditioning systems in ships.
22、 Annex B gives the thermal conductivities of commonly used construction materials. Users of this International Standard should note that, while observing the requirements of this International Standard, they should at the same time ensure compliance with statutory requirements, rules and regulations
23、 as may be applicable to the individual ship concerned. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of the
