Objectives
This proficiency assessment program's main objectives are to confirm the competent performance of the laboratory and indicate possibilities for improvements for the Rockwell B hardness and Rockwell C hardness testings applied to equipment/items that are subjected to this type of test.
Description
The Proficiency Testing Program (PTP) Hardness involves the determination of the hardness of a sample provided to participants. Any accredited laboratory or laboratory in the process of accreditation is eligible to participate.
Participants are required to test the sample according to their routine practice, choosing one or both of the following methods for the test:
Test Method | Range |
Rockwell | B |
Rockwell | C |
For quantitative tests, Qualabor uses the following order of priority in choosing the reference value:
01) Z' - Score with robust average - In the test area there are no clear quality levels between the laboratories that perform the same test, making it difficult to determine a laboratory with better quality recognized and accepted by the other participants. The use of the reference value by the group consensus is the most applicable, in this case being determined by the result of the robust mean, which does not require an independent treatment of outliers. To be able to use group consensus with minimal robustness, a group with 4 or more participants is required. The choice of the Z' score method is due to the greater acceptance of the participants and also because of the difficulty of calculating the measurement uncertainty by them, which is not necessary for this method.
02) Normalized 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 already 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.
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.

In case of a complaint or appeal of proficiency program results, the following steps should be followed:
- The participant should send Qualabor by email the complaint or appeal through pep@qualabor.com.br;
- When the email arrives at Qualabor, the participant will be notified that their complaint/appeal was received and may request information about its progress whenever necessary.
