What is BS 6888 - Calibration of bonded electrical resistance strain gauges about?
BS 6888 is a standard that covers the calibration of bonded electrical resistance strain gauges, ensuring the fulfilment of bonding characteristics and optimal performance in strain gauges.
BS 6888 describes methods for calibration procedures to determine the performance characteristics of bonded electrical resistance strain gauges that have metallic elements.
BS 6888 defines the terms used and states the accuracies required for instrumentation used for calibration purposes.
Note: BS 6888 does not cover the calibration of semi-conductor strain gauges.
Who is BS 6888 - Calibration of bonded electrical resistance strain gauges for?
BS 6888 on the calibration of bonded electrical resistance strain gauges applies to:
- Manufacturers of strain gauges
- Dealers and importers of strain gauges
- Testing houses and labs
- Quality assurance services
Why should you use BS 6888 - Calibration of bonded electrical resistance strain gauges?
Strain is the change in length per unit length in a specified direction of a specimen of material. Strain can be of different types such as mechanical strain, thermal strain and real strain. The bonded electrical resistance strain gauge is a device, which when strained after bonding to a surface gives a change in electrical resistance proportional to strain on the surface.
BS 6888 provides users guidance on performance characteristics of strain gauges, strain gauge installation for calibration tests, measuring equipment and strain gauge excitation, calibration procedures, calibration details supplied with packages of strain gauges, ensuring high strain limit and improved fatigue life at ambient temperatures.
BS 6888 provides users guidance on the performance characteristics of strain gauges including:
- Strain gauge resistance
- Strain gauge factor
- Transverse sensitivity
- Thermal output of strain gauge installed on test material
- Strain gauge factor changes with temperature
With obedience and compliance to BS 6888, users can calibrate bonded electrical resistance strain gauges, ensuring performance, high-temperature resistance, and long operating life.
What’s changed since the last update?
BS 6888:1988 supersedes BS EN 60721-3-3:1993, which is now withdrawn.
