EN ISO 898-3 Mechanical Properties of Fasteners Made of Carbon Steel and Alloy Steel

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN ISO 898-3 testing. This standard covers the mechanical and physical properties of flat washers designed for use in bolted connections with bolts, screws, studs and nuts of a particular property class in accordance with EN ISO 898-1 and EN ISO 898-2.

These types of washers can also be used with other fasteners, such as screws, that form their own mating threads.

Washers complying with the requirements of this standard are evaluated in the ambient temperature range of 10°C to 35°C. They may not maintain the specified mechanical and physical properties at high temperatures or low temperatures.

This standard applies to the following flat retaining and non-fixing washers made of carbon steel or alloy steel, with thickness from 0,2 mm to 12 mm:

  • Plain washers (with or without serration, ribbed or grooved);
  • Square stamps;
  • Square hole washers;
  • Shaped plates.

The standard defines feature classes for plain washers, represented by a numerical designation. These property classes specify the mechanical properties, such as tensile strength and hardness, that the flakes must have. Feature classes help users select appropriate washers for their applications based on the required power.

EN ISO 898-3 outlines test procedures and requirements for verifying the mechanical properties of flat washers. This includes testing methods for hardness, tensile strength and elongation, among others.

The standard may also include requirements for marking stamps to indicate compliance with specified property classes. Accurate marking helps users identify the correct stamps for their needs and ensures traceability.
