Parts numbering schema

The RespiraWorks parts numbering schema is designed with interdisciplinary maintenance of documentation in mind. Because of this, part numbers must be:

• semantically intuitive - reading the number should give you a rough idea of what this part is

• unambiguous - should be easy to disambiguate similar parts

Currently proposed (incomplete) schema is as follows:

CS-descriptor[-nn]

Mandatory sections:

• CS - Category + Subcategory

  • e - electrical

    • ee - electronics, computing

    • ep - power - batteries, external adapters, etc..

    • ew - wiring

    • ec - connectors

  • p - pneumatics

    • pa - active valves - solenoids, etc..

    • pp - passive valves - one-way, overpressure

    • pf - fittings and tubing adapters

    • pt - tubing

  • m - mechanical

    • mm - metal, sheet metal, etc..

    • mp - plastics, acrylic sheets, etc..

    • mh - hardware

  • c - cosmetic

    • cs - stickers, safety labels

  • t - tools

    • te - tools, electrical

    • tm - tools, mechanical

    • tp - tools, pneumatic

    • tc - tools, cosmetic

• descriptor - short alphanumeric descriptor, preferably around 4-5 characters long

Optional section:

The nn is some numeric suffix that may be added to disambiguate a part that would otherwise have the same code to the left of it.
