UNECE Regulation 10: Electrical/Electronic Sub-Assembly Radiated Emissions Testing (Annexes 7 and 8) and Radiated Immunity Testing (Annex 9)
In this installment in the series of blogs on UNECE Regulation 10, Revision 5, Amendment 1 (8 October 2016), hereafter referenced as R10.05, we will look at radiated emissions and immunity testing of Electrical/Electronic Sub-Assemblies (ESAs). ESA RADIATED EMISSIONS (Annexes 7 and 8) Like the vehicle radiated emissions testing annexes, R10.05 has separate … [Read more...]
UNECE Regulation 10: Vehicle Radiated Emissions & Immunity Testing (Annexes 4, 5 and 6)
Having dealt with the administrative side of Type Approval to UNECE Regulation 10, Revision 5, Amendment 1 (8 October 2016), hereafter referenced as R10.05, in the first three blogs in this series, this installment begins looking at the tests themselves commencing with the radiated emissions requirements of Annexes 4 and 5 and radiated immunity requirements of Annex … [Read more...]
UNECE Regulation 10: Worst-Casing
Before applying for a new Type Approval, or extension of an existing certificate, the applicable tests must be agreed with the Technical Service. A later blog in this series will cover the subject of approval extensions, so for this post we will consider new approvals. Where a manufacturer has multiple variants and/or configurations, worst-casing can significantly reduce … [Read more...]
UNECE Regulation 10: Conformity of Production
In this second blog in the series on Type Approval to UNECE Regulation 10, Revision 5 we will cover the subject of Conformity of Production (CoP) and explain why it is a critical part of the Type Approval process. The requirement for CoP is a fundamental element of the 1958 Agreement and the procedure is set out in Schedule 1 therein. Approval Authorities are required to … [Read more...]
UNECE Regulation 10: The Type Approval Process
Welcome to the first in a series of blogs on UNECE Regulation 10. In the first few blogs we will cover the fundamentals of Type Approval and the processes involved in obtaining an 'E' mark. Subsequent blogs will cover the various EMC test requirements set out in UNECE Regulation 10, Revision 5 (hereafter referred to as R10.05) in detail. Testing is only part of the … [Read more...]
