A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail other criteria, involving evidence of functionality or fitness for purpose.
An exploded-view drawing is a technical drawing of an object that shows the relationship or order of assembly of the various parts. [13] It shows the components of an object slightly separated by distance or suspended in surrounding space in the case of a three-dimensional exploded diagram.
Type G lines are used for centre lines. These are dotted lines, but a long line of 10–20 mm, then a 1 mm gap, then a small line of 2 mm. 2H pencil; Type H lines are the same as type G, except that every second long line is thicker. These indicate the cutting plane of an object. 2H pencil

The modern standard can trace its roots to the military standard MIL-STD-8 published in 1949. [4] It was revised by MIL-STD-8A in 1953, which introduced the concept of modern GD&T "Rule 1". [ 5 ] [ 6 ] Further revisions have continued to add new concepts and address new technology like Computer Aided Design and Model-based definition .
There are three main classifications of fire rated walls: fire walls, fire barriers, and fire partitions. A firewall is an assembly of materials used to delay the spread of fire a wall assembly with a prescribed fire resistance duration and independent structural stability. This allows a building to be subdivided into smaller sections.
