The Australian Building Codes Board (ABCB), [2] [3] [4] is a collective body formed in a partnership between the state, territorial, and national governments; and with representatives of the plumbing and building industries. [5] [6] [7] The ABCB was formed, by the three levels of government in an Inter-Government Agreement that was signed on 1 ...
The National Construction Code. The National Construction Code (NCC) is a set of minimum requirements for buildings in Australia. The requirements concern the aspects of health, safety, accessibility, amenity and sustainability of the types of buildings that the code applies to.
This code is also used as the basis for the plumbing codes of some other countries. Another model plumbing code published and utilized widely across the United States is the Uniform Plumbing Code , published by the International Association of Plumbing and Mechanical Officials ( IAPMO ), a multinational operation with offices in 13 nations.
[18] [19] Today, the degree, 1 / 360 of a turn, or the mathematically more convenient radian, 1 / 2 π of a turn (used in the SI system of units) is generally used instead. In the 1970s – 1990s, most scientific calculators offered the gon (gradian), as well as radians and degrees, for their trigonometric functions . [ 23 ]
In plumbing, the term "45-degree elbow" for example, refers to the angle of bend from the original straight pipe position (0 degrees) to the new position (45 degrees), not the actual angle formed by the joint. On a protractor, the actual angle of the above joint is 135 degrees, an obtuse angle.

Additionally, an angle that is a rational multiple of radians is constructible if and only if, when it is expressed as / radians, where a and b are relatively prime integers, the prime factorization of the denominator, b, is the product of some power of two and any number of distinct Fermat primes (a Fermat prime is a prime number one greater ...
