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 ...
The more than 50 classification societies worldwide each has different rules. 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 ...
A full-time bureaucracy of surveyors (inspectors) and support personnel was put in place. Similar developments were taking place in the other major maritime nations. The adoption of common rules for ship construction by Norwegian insurance societies in the late 1850s led to the establishment of Det Norske Veritas (DNV) in 1864.

These are not the only possible structural rules. A famous structural rule is known as cut. [1]
The first IACS Polar Class rules were published in 2007. [3] Prior to the development of the unified requirements, each classification society had their own set of ice class rules ranging from Baltic ice classes intended for operation in first-year ice to higher vessel categories, including icebreakers, intended for operations in polar waters.

[1] Its stated mission is to promote the security of life, property, and the natural environment, primarily through the development and verification of standards for the design, construction and operational maintenance of marine and offshore assets.
At that time, ships were classed by type and age, therefore there emerged a necessity in a more advanced system that would take into account structural features, strength, technical condition and navigation area. As soon as the end of the 19th century the first classification body was established. In 1899 the first classification rules emerged.
