Описание (английский):

La présente Norme internationale spécifie les caractéristiques des rondelles plates, série très large, de grade C, de classe de dureté 100 HV et de diamètre nominal (diamètre nominal de filetage) de 5 mm à 36 mm inclus. Ces rondelles conviennent à des - vis hexagonales de grade Cet de classes de qualité jusqu'à 6.8 inclus; - écrous hexagonaux de grade C et de classes de qualité jusqu'à 6 inclus; utilisés dans les structures en bois. Si des dimensions différentes de celles données dans la présente Norme internationale sont requises, il convient de les choisir parmi celles données dans l'ISO 887.

Overview

ISO 7094:2000 specifies requirements for plain washers - extra large series - Product Grade C. The standard covers washers with nominal thread diameters from 5 mm to 36 mm and defines material hardness, general dimensions and acceptance criteria for washers intended primarily for use with metric fasteners in timber structures.

Key points from the standard include:

Washers are of Grade C and made of steel with a nominal hardness of 100 HV (with an indicated hardness range up to 200 HV noted for related characteristics).

Preferred and non-preferred dimensional series are provided (see Table 1 and Table 2 in the standard).

The standard provides a model designation example: Rondelle ISO 7094-8-100 HV.

Key Topics

Dimensions and series: ISO 7094 lists preferred and non-preferred dimensions for extra-large plain washers. These are organized by nominal thread diameter and include recommended passage hole, outer diameter and thickness ranges.

Material and hardness: The document specifies steel washers with a hardness class of 100 HV, and references ISO 6507-1 for Vickers hardness testing methodology.

Tolerances and quality: Tolerances for flat washers are covered by ISO 4759-3; surface quality requirements state that parts must be free of burrs and harmful defects.

Surface finishes: Washers may be delivered unfinished, with protective lubricant, or with agreed coatings. Electrolytic coatings follow ISO 4042 and non-electrolytic zinc flake coatings follow ISO 10683.

Acceptance and testing: Reception and inspection procedures are referenced to ISO 3269.

Applications

ISO 7094:2000 washers are intended for practical engineering uses where larger bearing surfaces are required, particularly:

Structural timber assemblies using metric bolts and nuts.

Connections where increased bearing area reduces local compression on wood substrates.

Situations requiring standardized interchangeability with metric fasteners of Grade C and specified quality classes.

Benefits for engineers, specifiers and manufacturers:

Compatibility with commonly used metric bolts and nuts for timber construction.

Assured mechanical properties through defined hardness and referenced testing standards.

Clear designation and ordering information reduces procurement errors.
