The Temperature Rise in Toys Proficiency Testing Program (PEP) is the determination of the surface temperature rise of a sample, with accredited laboratory or accreditation process being eligible to participate.
Participants must perform the test as instructed by Qualabor, expecting values between 20 and 40 [° C]. The participant should proceed as in his / her practical routine according to ABNT NBR NM 300-6.
Qualabor ensures that the identity of participants in each program is confidential and known only to those involved in its operation, and becomes public only if the participant denies its confidentiality. Qualabor also warrants that all information provided by participants will be treated as confidential.
For quantitative tests Qualabor uses the following order of priority in choosing the reference value:
01) Robust Z - Robust Average Score - In the test area there are no clear quality levels between laboratories performing the same test, making it difficult to determine a laboratory with better quality recognized and accepted by other participants. The use of the reference value by group consensus is the most applicable, in this case being determined by the result of the robust average, which does not require independent treatment of outliers. To be able to use the least robust group consensus, a group of 4 or more participants is required. The choice of the Z score method is due to the greater acceptance of the participants and also to the difficulty of calculating the measurement uncertainty by them, which is not necessary in this method.
02) Standard error with reference value - When it is not possible to have a group with more than 3 participants, the reference value will be one previously validated with the participants and existing, being a value taken from an accredited laboratory. In this case, priority is given to the normalized error, since the denominator of the Z score is the standard deviation of the program, which has low robustness because it has few participants.
Qualabor's activities as a proficiency test provider are performed impartially, structured and managed to ensure this feature. Qualabor also warrants that any commercial, financial or other tensions will not compromise the impartiality of the provider. This is guaranteed by the "acknowledgment and agreement term" signed by Qualabor employees that affect the quality of the proficiency program.

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.
