Cracks were first discovered in December last year, on a Qantas-owned Airbus A380 that was being repaired after an engine explosion in Singapore. The Rolls Royce engine failure was caused by a fatigue failure in a fuel line pipe.
Certification And Test
Military vehicles used worldwide operate in harsh electro-magnetic environments caused by both coalition and enemy forces, so rigorous EMC testing is required at all times.
London 2012 is not just about the Olympics; it's also the location of the International Electrotechnical Commission (IECEE) CB scheme's annual meeting, which will include an industry workshop organised by the UK National committee.
Whether you are browsing the internet on your smart phone or cleaning your teeth with an electric toothbrush, batteries are an essential part of many of today's high-technology products. Whether it's high performance lithium ion (Li-ion) or more conventional nickel-metal hydride cell (NiMH), batteries present potential safety issues and therefore the use of batteries is addressed by a number of different standards.
I received some questions after my last blog post about the changes to RTCA/DO160G. Readers wanted to know more about the different sorts of chambers that we use to perform EMC testing.
The Test and certification industry is always evolving. Changes in existing legislation, new national requirements and standards following emerging technologies ensure there is never a dull moment.
Recently, I have been working my way through RTCA/DO160G, which is the latest revision of standard procedures and environmental test criteria for testing airborne equipment.
The old maxim of "how long is a piece of string" when given as an answer to your question doesn't really help anybody. However, in the case of global approvals, we at TRaC can certainly give you a good estimate of how long that piece of string is and in most cases a good idea of the maximum length!
I've just been updating some records against the latest version of the list of harmonised ATEX standards in the EU Official Journal
October 2011 sees the end of the transitional period from previous versions of EN55022 to the latest version which now requires testing above 1GHz for the first time. At the same time (beginning of October 2011) the Official Journal of the EU listing the harmonised standards for the EMC Directive has also been updated.
