All the standards

• International standards
• National standards
• Industry standards

There is a multitude of mechanical assembly parts and an even larger quantity of standards to describe them. These compulsory manufacturing standards impose geometrical and mechanical requirements on components and lay down the quality control procedures. While international standards are currently tending to standardize codes, references to national or aeronautic / aerospace industry standards ensure that differences remain. Knowing our way around standards and proper standard classification are major challenges at the heart of Satinox Assemblage’s expertise.

International standards: ISO, EN, CEI

ISO (International Standardisation Organisation) sets international standards and is composed of representatives from national organisations in 158 countries. The organisation was founded in 1947 and its objective is to produce international industrial and commercial quality standards known as ISO standards. They are applied in preference to national standards in all new developments.
At a lower level, the European Committee for Standardization is an ISO member whose objective is to standardize European standards under EN standards.

• ISO: International Standardization Organisation -> ISO standards
• CEN: European Committee for Standardization -> EN standards
• IEC: International Electrotechnical Commission -> IEC standards
• CENELEC: European Committee for Electrotechnical Standardization

National standards NF, DIN and BS

The older, national standards sometimes correspond to more specific requirements and standardize a larger quantity of items than the ISO standards. In some cases, the ISO standards are less demanding than certain national standards. In depth knowledge is therefore essential to properly classify standards for older systems.

• AFNOR: French National Organisation for Standardization -> NF Standards
• DIN: German Institute for Standardization -> DIN Standards
• ANSI: American National Standards Institute

Aeronautic and aerospace industry standards

Certain sectors such as aeronautics, aerospace or electronics have national or international standards which impose geometrical and mechanical conditions on components.
