Coordination dimensions are the actual physical dimensions of the brick with the mortar required on one header face, one stretcher face and one bed. Working dimensions is the size of a manufactured brick. It is also called the nominal size of a brick. Brick size may be slightly different due to shrinkage or distortion due to firing, etc. An ...
ASME Y14.41 is a standard published by American Society of Mechanical Engineers (ASME) which establishes requirements and reference documents applicable to the preparation and revision of digital product definition data (also known as model-based definition), which pertains to CAD software and those who use CAD software to create the product definition within the 3D model.
BS 8888 is the British standard developed by the BSI Group for technical product documentation, geometric product specification, geometric tolerance specification and engineering drawings. [ 1 ] History
A stock or stock board is an iron-faced block of wood fixed to the surface of the moulder's bench. The brick mould fits over the stock; the brick maker fills the mould with prepared clay and cuts it off with a wire level with the top of the mould, before turning out the 'green' brick onto a wooden board called a pallet for drying and firing.

Sizes of drawings typically comply with either of two different standards, ISO (World Standard) or ANSI/ASME Y14.1 (American). The metric drawing sizes correspond to international paper sizes . These developed further refinements in the second half of the twentieth century, when photocopying became cheap.
A size chart illustrating the ANSI sizes. In 1992, the American National Standards Institute adopted ANSI/ASME Y14.1 Decimal Inch Drawing Sheet Size and Format, [1] which defined a regular series of paper sizes based upon the de facto standard 8 + 1 ⁄ 2 in × 11 in "letter" size to which it assigned the designation "ANSI A".
Mudbrick or mud-brick, also known as unfired brick, is an air-dried brick, made of a mixture of mud (containing loam, clay, sand and water) mixed with a binding material such as rice husks or straw. Mudbricks are known from 9000 BCE. From around 5000–4000 BCE, mudbricks evolved into fired bricks to increase strength and durability.
