The standard is most often used as a comparative property in the specification of the conductivity of other metals. For example, the conductivity of a particular grade of titanium may be specified as 1.2 % IACS, meaning that its electrical conductivity is 1.2 % of the copper specified as the IACS standard. [2]
Polar Class (PC) refers to the ice class assigned to a ship by a classification society based on the Unified Requirements for Polar Class Ships developed by the International Association of Classification Societies (IACS). Seven Polar Classes are defined in the rules, ranging from PC 1 for year-round operation in all polar waters to PC 7 for ...
A logic without any of the above structural rules would interpret the sides of a sequent as pure sequences; with exchange, they can be considered to be multisets; and with both contraction and exchange they can be considered to be sets. These are not the only possible structural rules. A famous structural rule is known as cut. [1]
IACS is a non-commercial, technical collaboration association to establish, review, develop, and promote minimum technical requirements in relation to the design, construction, maintenance and survey of ships and other marine related facilities and to assist international regulatory bodies in the development and interpretation of statutory regulations to help ensure their universal and uniform ...
Oxygen-free copper is typically specified according to the ASTM/UNS database. [3] The UNS database includes many different compositions of high conductivity electrical copper. Of these, three are widely used and two are considered oxygen-free: C10100 – also known as oxygen-free electronic (OFE). This is a 99.99% pure copper with 0.0005% ...
IACS may refer to: Indian Association for the Cultivation of Science; Industrial Automation and Control Systems are also referred to as Industrial control systems; Innovation Academy Charter School; Integrated Administration and Control System; International Annealed Copper Standard, a unit of electrical conductivity
These ice classes can be assigned in parallel with the Finnish-Swedish ice class and/or the IACS Polar Class, provided the vessel complies with all applicable rules. The selection of ice class is based on the operating area in the Russian Arctic, time of year, ice conditions, operating tactics, and whether the vessel operates under icebreaker ...
However, most new ships are built to the standards of the 12 members of the International Association of Classification Societies, which implemented two sets of common structural rules - one for oil tankers and one for bulk carriers, in 2006. These were later harmonised into a single set of rules.
