The Multimeter proficiency scheme consists about comparing measurement error and uncertainty between a reference value and participant’s value for a digital multimeter, with any laboratory that does calibration tests being elegible to participate.
The participant must provide proficiency test item calibration and provide the result of this calibration through measurement uncertain and error, expecting the following values:
1 [Ω] to 200 [MΩ]
2,2 [mV] to 1 [kV] (AC)
0,1 [mV] to 1 [kV] (DC)
0,03 [mA] to 20 [A] (AC)
0,01 [mA] to 20 [A] (DC)
The participant must follow its practical routine.
Qualabor guarantees that the identity of the proficiency testing program participant is confidential and only known by the people involved into the proficiency testing program operation, unless the participant disclaims its confidentiality. Qualabor guarantees that all information given by participants is treated as confidential.
For calibration testing Qualabor uses Normalized error with reference value to establish the assigned value.
Normalized error with reference value – In the calibration area it is usually possible to choose as a designated value a laboratory at a level above in the traceability chain, which brings a better reliability to the assigned value than the consensus of the group. In this situation the uncertainties of good reliability are available from both the assigned values. The normalized error technique is opportune because it takes into account these uncertainties for the evaluation of participants' performance.
The activities of Qualabor as proficiency testing provider are done with impartiality and are structured and managed to guarantee the impartiality, Qualabor also guarantee that commercial, financial and other types of pressure will not compromise Qualabor’s impartiality. This is guaranteed through the acknowledgment and agreement term, signed by Qualabor collaborators who affect the quality of proficiency testing.
Registrations should be made through the Inscription Form at the tab “Inscriptions”
As the participants minimum number is met, the PT is confirmed
The PT’s samples will be send to the participants in a sequential or simultaneous manner in accordance with the PT
April - November
April - November
April - November
The preliminar report will have the final informations of the results of each participant. This report will be open for resources
Deadline for Resources
Each participant has the right to appeal the result obtained, requesting clarification and reassessment if necessary
* This schedule can be modified before the round confirmation for Qualabor, client or regulatory bodies’ necessity.
For this PT, the participant will be charged with the following values:
USD 1.000 (base value) + returning taxes (sending the sample to Qualabor after the tests) + other taxes (if applicable according to the country of origin of the participant, the participant will bear the costs, without paying this taxes to Qualabor)
Qualabor accreditation process is actually in progress.
Qualabor's QMS is implemented and effectively maintained according ISO/IEC 17043.
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.
