ISO 7839:2005

Overview

ISO 7839:2005 - Textile machinery and accessories - Knitting machines - Vocabulary and classification - is an international standard that defines the terminology and classification scheme used for knitting machines and their accessories. Published by ISO/TC 72 (Textile machinery), this second edition (2005) replaces the 1984 edition and provides harmonized terms in English and French, with German equivalents published under DIN responsibility. The standard is intended to create consistent language for manufacturers, engineers, technical authors and educators working in the knitting industry.

Key topics

The standard organizes terms and definitions into two principal sections:

• Main characteristics

  • Needle moveability (e.g., knitting machine with independent needles, knitting machine with united needles)
  • Direction of yarn feed (weft knitting vs. warp knitting)
  • Arrangement of needles (flat knitting machines, circular knitting machines)
  • Number and kind of needle carrier (single-face RL, double-face RR, purl LL machines)

• Customary machine types

  • Weft knitting - independent-needle machines, flatbed knitting machines
  • Specialized forms such as V‑bed flat knitting machines and V‑bed machines with a traversing carriage
  • Alphabetical indexes in English, French and German to support cross-referencing and translation

Other technical features in the standard include structured, language-specific definitions and classification criteria so terms are used consistently across documentation, specifications and technical communication.

Practical applications

ISO 7839:2005 is useful for:

• Textile and knitting machinery manufacturers - to standardize product descriptions, manuals and technical data sheets.
• Knitting mill engineers and technicians - for unambiguous machine identification, maintenance records and procurement.
• Technical writers and translators - to ensure consistent terminology across English, French and German documents.
• Educators and trainers - as a reference for teaching machine types and fundamental terminology.
• Standards committees, certification and regulatory bodies - to reference uniform definitions during conformity assessment and specification writing.

Benefits include improved clarity in procurement contracts, reduced ambiguity in international trade, consistent cataloguing of machine types (e.g., flat vs. circular, RL/RR/LL distinctions), and smoother collaboration among OEMs, suppliers and end users.
