During this test, the measuring to be determined is the dimensional quota of creepage and insulation, expecting maximum value of 50 [mm]. The participant must proceed as in its routine, using as reference IEC 60664 and IEC 60950-1
The statistical model used on this program will be: Z' Escore, comparing the participant's result with the robust average of the group's accredited laboratories only.
This is one of CGCRE's program, organized and constant at SCT de Instalações Elétricas e Baixa Tensão da CT08 (Eletronics Technical Committee of CGCRE), also this program meet the requirements of NIE CGCRE 045's standard.

EPTIS helps you find a suitable proficiency testing (PT) scheme for your laboratory (a PT scheme is a coherent series of single rounds). For a large number of schemes we have produced data sheets and collected them in the EPTIS database. What is not included in the database is topical information on next PT rounds. When is the next round, and what is the matrix material this time? This information is too dynamic as to be included in the database. But you can find such details for a selection of schemes in our PT calendar.
At present, a listing on the database is only open to PT providers from countries that are covered by our so-called coordinators. They check the plausibility of the data sheet submissions and decide on their publication. They speak the language and are ideally familiar with local PT providers and cultural peculiarities. This helps to safeguard a reasonable level of database quality. There is no cost for PT providers who follow this basic mechanism.
