Independent metallurgical specialist, Keighley Laboratories, points out that with growing volumes of steel, alloys and metal components being sourced in the Far East from comparatively unknown suppliers, and manufacturers in this country ultimately responsible for any component failures, there is now a pressing need to re-inspect, or overcheck, material certifications. In support of this view, the company draws attention to a recent US study, in which 133 out of 220 samples of imported steel rod were rated as failures by a certified test laboratory, an astonishing 60% failure rate.
