Specifically addressed in the BS 6072 Specification
Used to check if an induced field will detect a certain orientation (direction) of defect
The Western Instruments Castrol Strips Flexible Magnetic Flux Indicators is specifically addressed in the BS 6072 Specification, Western Instruments Castrol Strips Flexible Magnetic Flux Indicators are used to check if an induced field will detect a certain orientation (direction) of defect, and to determine the sensitivity or size of a detectable defect.
Western Instruments Castrol Strips Flexible Magnetic Flux Indicators are more robust than QQI's, as they are over 3 times thicker. Therefore, Castrol Strips are very suitable for use in the field or factory floor, by a Technician to check his defect sensitivity. While Castrol Strips can be used for procedure development they are far more suited to repeated use. Furthermore, Type G Castrol Strips are the best suited for field operations, while Type A are more similar to QQI's with the disadvantage of not being as flexible.
