As a precautionary measure, a piece twice as big as the one required by the protocol was cut from the Shroud; it measured 81 mm × 21 mm (3.19 in × 0.83 in).An outer strip showing coloured filaments of uncertain origin was discarded.The lab representatives were not present at this packaging process, in accordance with the protocol.The labs were also each given three control samples (one more than originally intended), that were: and communicated their results to the British Museum. The blind-test method was abandoned, because the distinctive three-to-one herringbone twill weave of the shroud could not be matched in the controls, and it was therefore still possible for a laboratory to identify the shroud sample. group expected to perform the radiometric examination under its own aegis and after the other examinations had been completed, while the laboratories considered radio-carbon dating to be the prime test, which should be completed at the detriment of other tests, if necessary.
Prof H E Gove, former professor emeritus of physics at the University of Rochester and former director of the Nuclear Structure Research Laboratory at the University of Rochester, helped to invent radiocarbon dating and was closely involved in setting up the shroud dating project.
that discarding the blind-test method would expose the results – whatever they may be – to suspicion of unreliability.
Shredding the samples would not solve the problem, while making it much more difficult and wasteful to clean the samples properly.
It is hypothesised that the sampled area was a medieval repair which was conducted by "invisible reweaving".
Since the C14 dating at least four articles have been published in scholarly sources contending that the samples used for the dating test may not have been representative of the whole shroud.
