Every chain that is received from the factory arrives with a detailed master certificate which includes many details such as the dimensions, material details, tensile strength and test data. Key information that we require to produce a test certificate for each batch of the chain.
The master certificate is then held by FB Chain for posterity. Over the years, the number of master certificates held by us has grown significantly and resulted in a great deal of space being taken up storing them, as they were paper copies. It also meant that finding an old master certificate could at times be a cumbersome job.
