What is EN ISO 898-1:2018?

This article aims to provide an easy-to-understand explanation of the standard EN ISO 898-1:2018, which is related to mechanical properties of fasteners made of carbon steel and alloy steel. The standard provides requirements for bolts, screws, and studs with specified property classes and thread diameters.

of the Standard

The EN ISO 898-1:2018 standard specifies mechanical and physical properties that fasteners must meet in order to ensure their quality, reliability, and performance. These properties include tensile and proof loads, elongation, hardness, and impact strength. The standard also defines different property classes, ranging from 4.6 to 14.9, based on the mechanical properties required for each class.

Contents of the Standard

The standard EN ISO 898-1:2018 consists of several parts that cover different aspects of fastener manufacturing and testing. Part 1 of the standard sets out the general requirements and includes tables specifying the mechanical properties for each property class. It also provides guidance on the marking of fasteners to indicate compliance with the standard.

Other parts of the EN ISO 898-1 series cover additional topics such as torsional test methods, selection of samples for mechanical testing, and verification of hydrogen embrittlement resistance. These parts provide more detailed information for manufacturers and testing laboratories.

Application of the Standard

The EN ISO 898-1:2018 standard is widely used by manufacturers and suppliers in the fastening industry to ensure that their products meet the necessary quality standards. Compliance with the standard helps to guarantee that fasteners have the required strength and durability to perform their intended function safely and reliably.

Furthermore, the EN ISO 898-1:2018 standard is often referenced by engineering professionals, designers, and architects when selecting fasteners for structural applications. By specifying fasteners that comply with the standard, they can have confidence in the performance and integrity of their designs.
