Overview
EN ISO 7094:2000 - Plain washers - Extra large series - Product grade C (ISO 7094:2000) defines the characteristics of plain (flat) washers in the extra large size range and designates the required quality level as Product grade C. This European adoption (CEN) was also published in Slovenia as SIST EN ISO 7094:2002. The document sits under ICS 21.060.30 (washers, locking elements) and was migrated from a progress sheet; ISO action on withdrawal of ISO 7091 & 7094 was noted in the historical record.
Key topics and technical requirements
While avoiding specific numerical values (see the standard for exact dimensions), EN ISO 7094 typically addresses:
- Scope and definitions for plain (flat) washers in the extra large series.
- Dimensional requirements: nominal external diameters, inside (bore) diameters and thickness classes for the extra large range.
- Tolerances and permissible deviations for form and size to ensure interchangeability.
- Product grade C requirements, indicating the intended manufacturing/quality level and acceptance criteria.
- Marking, identification and packaging expectations to support traceability and correct use.
- Reference to testing or inspection methods applicable to ensure compliance with the standard.
For precise figures, tables and tolerances, consult the official EN ISO 7094:2000 text.
Applications
EN ISO 7094 is relevant wherever larger-diameter plain washers are required to distribute loads, protect surfaces or maintain assembly geometry. Typical applications include:
- Structural and heavy mechanical assemblies where extra-large washers prevent bearing failure.
- Fastening systems in construction, heavy machinery, rail and offshore equipment.
- OEM manufacturing and repair workshops specifying standardized washers for interchangeability.
- Procurement and inventory management when selecting ISO-compliant fastener accessories.
Who uses this standard
- Mechanical and structural engineers specifying fastenings
- Fastener and washer manufacturers producing to international standards
- Quality assurance and inspection personnel verifying compliance
- Procurement officers and technical buyers requiring standardized parts
- Standards bodies and certification organizations referencing washer grades
