I realise that this may be largely legal in nature and may be off topic, but I think that the users of this site are most likely to be able to answer accurately, so I shall ask and risk being shot down!
We have a device (which I helped to design) that we have sold globally for a long time with no issues. It was tested against the following standards in 2014:
- EN 55022:2010 incorporating corrigendum October 2011
- EN 55024:2010 incorporating corrigendum 2011
- 47CFR15.109 ICES-003 Issue 5 August 2012
However, an Australian reseller that we have just shipped an order to asked to see test reports (including some which were not relevant, which made me question their understanding of the matter). We sent them over and they have accepted them, but were not happy that the test results were over a year old. They suggested that the next shipment will require test results taken in the previous 12 months.
Has anyone else ever heard anything like this? Sounds like rubbish to me - we haven't changed the design, we haven't changed any suppliers and I don't remember physics having changed in the last 12 months - but is it another weird legal requirement? Is this particular to Australia, or is it also the case in other countries?
Secondarily, thinking about this, it strikes me that these standards may be updated in the future. Will we be required to retest every time that a standard has an update, or can we continue in perpetuity once a product has been certified provided that no additional legislation is passed which precludes the sale (I'm thinking about things like the RoHS and WEEE legislation which changed the landscape for a lot of products, but had a grace period built in).
