BS EN 12680-3 provides a set of guidelines for founding the ultrasonic testing and is the third part of the multi-series standard that consists of spheroidal graphite cast iron castings.
BS EN 12680-3 specifies the requirements for the ultrasonic testing of spheroidal graphite cast iron castings and the techniques for determining internal discontinuities by the pulse-echo technique.
NOTE 1: BS EN 12680-3 does not apply to ultrasonic testing of the nodularity of spheroidal graphite cast irons.
NOTE 2: BS EN 12680-3 does not apply to transmission technique.
NOTE 3: The transmission technique has insufficient sensitivity to detect the discontinuities found in spheroidal graphite cast iron castings and is used in exceptional cases only.
BS EN 12680-3 on Ultrasonic testing is useful for:
Spheroidal structure is a basic requirement for semisolid structure. These help to improve formability of the material during processing, and allows to produce a better geometric shaped cast irons through ultrasonic testing.
BS EN 12680-3 standard consists of guidelines for the cookware utensil manufacturers with the guidelines of ultrasonic testing for spheroidal graphite cast iron castings.
BS EN 12680-3 consists of guidelines which help the buyers of cookware utensils to use a sturdy product.
