Class: Pubid::Bsi::Identifiers::AerospaceStandard

Inherits:
SingleIdentifier show all
Defined in:
lib/pubid/bsi/identifiers/aerospace_standard.rb

Overview

AerospaceStandard handles BSI aerospace and specialized standards with letter prefixes indicating domain categorization.

Categorization includes:

  • Aircraft (A, B, C, F, G, HC, L, S, SP, X)

  • Methods related to aircraft (M)

  • Marine (MA)

  • Polyester (PL)

  • Aerospace materials (TA for Titanium-Aluminium alloys)

  • Automotive (AU)

  • Multi-letter prefixes (2A, 2B, 2C, 2F, 2G, 2HC, 2HR, 2L, 2M, 2S, 2SP, 2TA, 2X, etc.)

Examples:

BS A 109:2024       # Aircraft (A prefix)
BS AU 145e:2018     # Automotive (AU prefix) with letter suffix
BS M 38:1971        # Methods (M prefix)
BS 2A 293:2005      # Multi-letter prefix (2A)
BS SP 113:1954      # Specification (SP prefix)
BS TA 40:1971       # Titanium-Aluminium (TA prefix)
