What is BS EN 4859 about?
BS EN 4859 is a European standard on clamp load determination that discusses the methods and criteria for determining clamp load of high tensile bolts. BS EN 4859 specifies the technical, qualification, and quality assurance requirements for sensor-based clamp load measurement systems for high tensile bolts and other clamp load-sensitive elements.
Primarily for aerospace applications, it applies to such products when referenced on the product standard or drawing.
Who is BS EN 4859 for?
BS EN 4859 on sensor-based clamp load determination is relevant to:
- Manufacturer of bolts and sensor bolts
- Mechanical engineer
- Aerospace industry
Why should you use BS EN 4859?
The clamp load, also called preload of a fastener, is created when a torque is applied, and so develops a tensile preload that is generally a substantial percentage of the fastener's roof strength.
BS EN 4859 provides guidance on clamp load measurements on bolts, the configuration of thin-film, transducer-based sensor bolts, determination of the clamp load on thin-film transducer-based sensor bolts, basic components of an ultrasonic measurement system.
BS EN 4859 exemplifies geometrical requirements on sensor bolts, certification, and quality assurance for thin-film transducer-based sensor bolts.
As a user of BS EN 4859, you can be ensured of quality assurance requirements for sensor-based clamp load measurement systems. With obedience and compliance to BS EN 4859, you can efficiently calculate the clamp load on the bolt this helps the user to determine the durability of the bolt and the function of a threaded joint. BS EN 4859 helps you in manufacturing good quality high tensile bolts.
