ISO 15165:2001

Overview

ISO 15165:2001 - Fine ceramics (advanced ceramics, advanced technical ceramics) - Classification system - defines a flexible, machine‑readable coding framework for classifying fine (advanced) ceramic materials and components. The standard covers inorganic precursors, powders, granules, fibres, whiskers, platelets, single crystals, consolidated polycrystalline ceramics, glassy/amorphous and composite materials, and components in block, thin‑film and coating forms. It provides a recommended international coding system that users can adapt to their own level of detail and application.

Key topics and technical requirements

• Classification fields: The system is built from independent classification fields identified by initial letters:
  • A = Application (three‑digit application codes; hierarchical grouping by principal function)
  • C = Chemical character (form + species; short and long formats)
  • P = Processing methods
  • D = Property data
• Chemical coding formats:
  • Short format: 4‑digit codes for broad commercial or inventory descriptions (range 5001–9999).
  • Long format: Detailed, repeatable sequences identifying individual chemical species and optional mass fractions (codes 0001–4999).
• Machine‑readable structure: Codes are alphanumeric strings designed for database and automated processing. Users may concatenate fields in any sequence suitable to their objectives.
• Normative and informative annexes: Annexes A, B and D are normative (application, chemical descriptor, property data); Annexes C and E provide informative guidance (processing, bibliography).
• Scope exclusions: Traditional clay‑based ceramics (whiteware, tiles, sanitary ware, building ceramics), bulk refractories, most elemental carbon and elemental semi‑metallic substances (except when integral to fine ceramics), and hardmetals are generally excluded.

Practical applications and users

ISO 15165 is intended for:

• Materials scientists and R&D teams classifying new ceramic compositions and documenting properties.
• Manufacturers and suppliers organizing product catalogs, inventory and quality records.
• Database managers and informatics teams implementing machine‑readable material identifiers.
• Procurement, standards bodies and trade analysts performing market surveys, commercial statistics and cross‑border classification.
• Design and engineering teams needing unambiguous material identifiers for specifications, coatings, thin films and composites.

Practical uses include product identification, materials data banks, trade statistics, specification writing, and linking chemistry → processing → properties → application in traceable, searchable form.

Related standards

• ISO 15165 references electrotechnical ceramic standards such as IEC 60672‑2 and IEC 60672‑3 for test methods and material specifications; users should consult these normative references where relevant.
