Hi, A couple of comments on the pacemaker standards. 1. Under the AMID, you must involve a Notified Body. The only reasonable route to the CE marking is Annex 2 (full QA) and submittal of the Design Dossier. 2. All accessories to a AIMD (i.e. programmers) are also under the scope of

As an excerise, I tried to find the directive that this standard was harmonized under. I looked on the Europa site under the EMC, Medical Device, and Active Implantable Medical Device directives to no avail. http://europa.eu.int/comm/enterprise/newapproach/standardization/harmstds/reflist.html

I have had products with this type of construction. I have products with IEC-320-C14 inlet molded power cords that I have sent through VDE for IEC 60950 / EN 60950 approval and I have not had any compliance issues. I have also owned a number of UL /CSA approved computer monitors with this

Appliance Inlet Integral to Power Cord

Dear All, I have an ITE product with a power cord terminated at the end with a molded-on IEC320 inlet (similar to an inlet used on an appliance but this one is terminated at the end of the cord). This inlet is used to mate with a detachable cord set in the field. Q. Does any one have a problem

Dear Nakamura-san; The best explanation of the CB Scheme is at www.cbscheme.org . It is a global reciprocity agreement dealing with IEC 60950 for the safety of ITE products. If one CB (certification body) generates a CB test report for a product, all other members are to accept the test
