What is BS EN ISO 898-2:2012?

BS EN ISO 898-2:2012 is a technical standard developed by the British Standards Institution (BSI) and adopted as an International Organization for Standardization (ISO) standard. It specifically relates to the mechanical properties of fasteners made of carbon steel or alloy steel when tested at ambient temperature.

Scope of the Standard

The scope of BS EN ISO 898-2:2012 covers various types of fasteners, including screws, bolts, and studs, and specifies their mechanical properties such as tensile strength, yield strength, and elongation. It provides guidelines for testing these properties using different techniques. This standard is applicable to fasteners with a coarse thread, fine pitch thread, or a special thread design.

Testing Methods

BS EN ISO 898-2:2012 outlines several methods for testing the mechanical properties of fasteners. One of the most common tests is the tensile test, which measures the maximum load a fastener can withstand before breaking. It evaluates the ultimate tensile strength and elongation characteristics. Another important test is the proof load test, which determines the level of static axial load a fastener can sustain without permanent deformation.

Additionally, the standard specifies hardness tests that assess the surface hardness and core hardness of fasteners. It also includes tests such as torque/clamp force testing and rotational capacity evaluation for fasteners used in specific applications.

Benefits and Importance

BS EN ISO 898-2:2012 plays a crucial role in ensuring the quality, reliability, and safety of fasteners used in various industries. Compliance with this standard ensures that fasteners can withstand the expected loads and environments they are intended for. It helps manufacturers in designing, producing, and selecting appropriate fasteners that meet specific mechanical requirements.

Adhering to this standard also facilitates international trade, as it provides a common framework for evaluating and comparing fasteners produced by different manufacturers across the world. It enhances confidence among consumers, engineers, and regulatory bodies, knowing that the fasteners they utilize or approve meet established quality standards.

In conclusion, BS EN ISO 898-2:2012 is an essential technical standard governing the mechanical properties of carbon steel and alloy steel fasteners. Its comprehensive guidelines for testing and evaluating various mechanical characteristics ensure the reliability and safety of these crucial components in different applications. Manufacturers, engineers, and consumers benefit greatly from the adherence to this standard, promoting consistent quality and performance in the fastener industry worldwide.
