Objectives

This proficiency assessment program's main objectives are to confirm the competent performance of the laboratory and indicate possibilities for improvements for the Dieletric Strength test applied to equipment/items that are subjected to this type of test.

Description

The Proficiency Testing Program (PTP) for Dielectric Strength Applied Tension involves determining the voltage at which a disruptive discharge (current loss) occurs in the sample. Any accredited or accreditation-seeking laboratory is eligible to participate.

Participants should test the sample expecting values between 0 and 2000 [V] and perform the test according to their routine practice.

For quantitative tests, Qualabor follows the following order for assigned value choice priority:

1) Z' - Score with the robust average - In the area of testing there are no clear levels of quality between laboratories for the same test, this way is hard to determine a laboratory with recognition of a higher quality that is accepted by the other participants. The use of an assigned value from a group consensus is the most applicable, In this case, determined by the result's robust average, which does not require an independent treatment of outliers. To be able to use group consensus with minimal robustness is necessary a group with 4 or more participants. The choice of the z'-score method is due to the same being of greater acceptance by the clients and also by difficulties in calculating uncertainty of measurement by the participants, which is not sensitive to this method.

02) Normalized error with a reference value – When it is not possible to have a group with more than 3 participants, the assigned value utilized will be a reference value, previously validated with participants and always that exists, this value will be taken through an accredited laboratory, and in this case is given priority to the normalized error because the denominator of z' score is the program standard deviation which has low robustness because there are few participants.

The activities of Qualabor as a proficiency testing provider are carried out with impartiality, structure, and management to ensure such characteristic. Qualabor guarantees that the identity of participants in each program is confidential and only known by those involved in its operation, becoming public only if the participant denies their confidentiality. Qualabor also ensures that all information provided by participants will be treated as confidential.

Qualabor also guarantees that any commercial, financial, or other tensions will not compromise the impartiality of the provider. This is ensured by the "acknowledgment and agreement term" signed by Qualabor's employees who affect the quality of the proficiency program.

EPTIS

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.
