Gert, "My customer wants to approve a wireless bed wetting alarm system at this very moment:
R&TTE for the wireless MDD for medical applications in hospital environments EMC for the and receiver and alarm part LVD for the supply part" I believe if your client meets the MDD only (covers safety, emc, radio, environmental, quality) it should be good enough for other non-medical applications Regards,.

There are however, several documents within the CENELEC that have other opinions, and want to treat the combination according to different directives and standards depending on the mode of operation ( inoperating / standby /sending /receiving). To my opinion this is not gonna work, as sometimes 4-5 directives may be applicable to a product and not one of the directives may cover a product in full. An intelligent decision needs to apply each directive on the appropriate part of the full apparatus (system). Example: My customer wants to approve a wireless bed wetting alarm system at this very moment: R&TTE for the wireless MDD for medical applications in hospital environments EMC for the and receiver and alarm part LVD for the supply part Of course this way the end user (system assembler) needs to follow a modular approach, and has to treat the wireless part fully separated. If one decides to integrate the wireless chip set etc. on a PCB containg an ITE application, then the R&TTE will be applicable to the device as a whole.. In general The properties of equipment are rapidly changing. A typical kitchen application could be tested accrding to EN 55014 easily. Now mikroprocessors made their entry in kitchen equipment , and bluetooth or TCP/IP stacks are added. Does the standard vacuum cleaner to be characterised according to it's function ?? Does it become an ITE because of the Internet interface ? What do you think of a cow milking apparatus ? Typical EN 55014 ! And what if it incorpates a robot concept using over 12 microprocessors, frequency convertors, pneumatics and laser technology as well as a wireless remote control function ? Another approach is the "port" approach, where suitable emc tests are selected according to the ports properties and expected signals, and not on the properties / function of the apparatus. This looks a bit like the Generics approach (EN 5008x-x and IEC 61000-6-x) standards. A third point of view is that a suitable test set may be determined on a phenomenae approach. Wideband or small band (or both) interference, conducted emssions for SMPS etc. This requires an insight in the equipments way of operation and bears the risk of overlooking certain aspects. Anyone wants to add to this discussion ?...

Does RTTE apply? Thanks in advance George Stults ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
