I have no timeframe stuck in my head, I take each item and where it is and it's use and make my decision on that . Instead of digging at me for my choice of retest of something that I have seen you could have just agreed that not everyone is following accepted testing procedure.
I wasn't "digging at you". In fact I was agreeing with you that a decision should be taken based on the circumstances of how it is used, any deterioration which has occured over time, etc. I was also pointing out that many people fail to understand that different equipment should have different timeframes for Combined Inspection and Testing depending on how onerous the environment in which they are used, etc. as well.
So I really don't understand why you think I was having a go at you.
