S/W many thanks, was that upgrade to a 2009 or 1909?
BGB
As S/W mentions there were numbers in 00-56 and they have been used. The appropriateness of use is where my original question was aimed. The reason I asked when the change came about, is because I have seen the numbers recently. Now that is probably because of the standards called up when the RFQ was put out. However, in the future it could be expensive to take them out as the whole safety case would have to be re-visited and the answer may not be palatable. Additionally, because the guidance has disappeared, I think that some later safety cases are reaching back and still using the Issue 2 numbers because it is assumed that they are legitimate.
