KEMA Laboratories 90 years 2012-2014

Reports and Certificates
From the early beginning till approximately 1960-ties the KEMA test reports were technical documents intended for the R&D section of the manufacturer. Standards became available in 1960 and onwards and components were more and more tested to these standards. When a component successfully met the standard the test report was also used as proof to utilities that a component meets the requirements, is of good quality and can to be used in the power network.

With the globalization of standards in IEC, CENELEC, IEEE and others, KEMA’s focus shifted towards type testing of components. Test reports became Certificates and utilities around the world recognized a KEMA Certificate as the independent statement of quality for T&D components. The brand name KEMA was clearly established in the global market.

From the early beginning KEMA reports were green leather bound documents with a golden embossed title; very well recognizable documents. The oldest KEMA Certificate present in our archive date back to 1964. The looks of the reports did not change much over time just some small adoptions when KEMA changed the logo.

The content inside a KEMA test report was a listing of the test performed and often without a clear indication of a test was passed or failed. It was up to the reader to make that decision and utilities in the early days had sufficient knowledge to make that judgement. Around the turn of the century, utilities requested that KEMA should make a clear conclusion in the report if a component successfully meets all type test requirements of the standard. In 2004, this lead to a big change in the reporting style where we made three categories of reports.

Gold: KEMA Type Test Certificate
With its gold-embossed cover and gold seal, the KEMA Type Test Certificate is the hallmark of a high-quality component. It signifies that the component successfully passed all the Type Test tests per an international standard including verification of the technical drawings and a visual inspection. For utilities, a gold KEMA Type Test Certificate tells that the component meets all requirements of the standard and no further effort is needed to assess it.

Silver: KEMA Report of Performance
A KEMA Report of Performance is issued when a component successfully passes a subset of a Standard’s Type Test program including verification of technical and a visual inspection. Identified by its silver-embossed cover and seal, a KEMA Report of Performance tells the end customer that the component partly meets the requirements of the Standard’s Type Test program. The end customer may use these results and test program to determine if they are applicable and sufficient for their needs.

Grey: KEMA Test Report
In all other cases where tests are performed at a KEMA Laboratory, a KEMA Test Report, with a grey-embossed cover and seal, is issued. This could mean tests were performed per customer’s specifications or that the tests did not fulfil the requirements of a standard. When utilities and network operators see a grey KEMA Test Report, they themselves must read it carefully to assess the component’s performance. This requires deep technical knowledge of standards and expertise on how to interpret them.

Apart from testing in our own laboratories KEMA performs to a limited extent the witnessing of tests performed in the laboratory of the manufacturer. The results of the test are reported in a KEMA inspection report. These reports do not have the green leather cover but a white cover for making a distinction between laboratory testing, where we have 100% control over the execution and interpretation of the test, and inspection based witnessing where we have limited control over the execution of the test. Consequently, certification is also not possible.

After the merger with DNV in 2012 and a few years later with GL to become DNV GL it was decided to maintain the KEMA brand for the testing activities in the laboratories. The name changes to KEMA Laboratories as product brand from the DNV GL.
