ISO 14617 Graphical symbols for diagrams is a library of graphical symbols for diagrams used in technical applications. [1] ISO 14617 consists of the following parts: Part 1: General information and indexes; Part 2: Symbols having general application; Part 3: Connections and related devices; Part 4: Actuators and related devices
It is numbered with a stylized flag symbol surrounding the number (or sometimes a delta symbol). A general note applies generally and is not called out with flags. 2. Find number: "FN" meaning "find number" refers to the ordinal number that gives an ID tag to one of the constituents in a parts list (list of materials, bill of materials).
A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard S5.1
Compression ratio – The static compression ratio, (symbol ), [45] of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its largest capacity to its smallest capacity. It is a fundamental specification for many common combustion engines.
This is an incomplete list of DIN standards. The "STATUS" column gives the latest known status of the standard . If a standard has been withdrawn and no replacement specification is listed, either the specification was withdrawn without replacement or a replacement specification could not be identified.

The list of materials (L/M, LM, LoM), bill of materials (B/M, BM, BoM), or parts list (P/L, PL) is a (usually tabular) list of the materials used to make a part, and/or the parts used to make an assembly. It may contain instructions for heat treatment, finishing, and other processes, for each part number.
