BS 9690-1:2011 PDF

What is this standard about? BS 9690-1 provides general principles and defines specifications for non-destructive testing (NDT) using guided stress waves. Who is this standard for?

Anyone involved in non-destructive testing Manufacturers/designers of products suited to NDT testing

Why should you use this standard? Guided stress waves used for NDT are sonic or ultra-sonic waves which travel along an object and are guided by its surfaces or shape, and whose wavelength is large compared to a characteristic dimension such as wall thickness. It is therefore suited to the testing of elongated objects such as pipes, tubes and rails. This part of BS 9690 provides the general principles for guided wave testing. The specific conditions of application and use of guided wave testing, which depend on the type of object tested, are described in documents which could include: a)      Product standards b)      Specifications c)       Codes d)      Contractual documents e)      Written procedures Unless otherwise specified in the referencing documents the minimum recommendations of this standard are applicable.
