This document describes the specification of high manganese (Mn) austenitic steel plates to be used for LNG tanks on board ships. The specification of high manganese austenitic steel can be also considered for design and manufacture of cargo tanks and process pressure vessels of LNG supply/terminal and transportation of fuels and traded gases. This document is primarily applicable for the specification of LNG tanks below volumetric capacity of approximately 30 000 m3 using high manganese austenitic steel. The thickness of plates is limited to between 6 mm to 40 mm.

This European Standard specifies properties and technical conditions for inspection and delivery of wrought and cast aluminium and aluminium alloy products recommended for marine applications, including shipbuilding and offshore applications. Additional information is given about high magnesium alloys, with special regard to their sensitivity to intergranular and exfoliation corrosion. This European Standard is intended to be used in conjunction with relevant European, national or international regulations as applicable, to which it comes in support. For products intended to be used in marine constructions to be classified by a Classification Society, the relevant requirements of this Society apply. This European Standard covers: - wrought products in aluminium alloys (see Clause 6); - castings in aluminium alloys (see Clause 7). Information is given in Annex A to guide the user in the selection of aluminium and aluminium alloys and tempers for various applications. This European standard does not cover: - execution and design, covered by the rules of the Classification Societies or EN 1090-3 and EN 1999-1-1 to EN 1999-1-5; - welding, covered by EN 1011-4.

The formulae specified in this International Standard are intended for the establishment of a uniformly acceptable method for calculating the pitting resistance and bending strength capacity for the endurance of the mainpropulsion and auxiliary gears of ships, offshore vessels and drilling rigs, having straight or helical teeth and subject to the rules of classification societies. The rating formulae in this International Standard are not applicable to other types of gear tooth deterioration, such as plastic yielding, micropitting, scuffing, case crushing, welding and wear, and are not applicable under vibratory conditions where there may be an unpredictable profile breakdown. The bending strength formulae are applicable to fractures at the tooth fillet, but are not applicable to fractures on the tooth working profile surfaces, failure of the gear rim, or failures of the gear blank through web and hub. This International Standard does not apply to teeth finished by forging or sintering. This standard is not applicable to gears having a poor contact pattern. This International Standard provides a method by which different gear designs can be compared. It is not intended to assure the performance of assembled drive gear systems. It is not intended for use by the general engineering public. Instead, it is intended for use by the experienced gear designer who is capable of selecting reasonable values for the factors in these formulae based on knowledge of similar designs and awareness of the effects of the items discussed. WARNING — The user is cautioned that the calculated results of this International Standard should be confirmed by experience.
