BTRA PROFICIENCY TESTING PROVIDER

ACCREDITED PROFICIENCY TESTING PROVIDER AS PER ISO/IEC 17043

Testing laboratories play a major role in the evaluation of the quality of different products including textiles including geotextiles (mechanical and chemical with analytical). The results being reported by the testing laboratories are crucial in deciding the fitness of purpose of a product manufactured. The results should be reliable, repeatable, and reproducible. The competence of testing laboratories can be demonstrated by documenting and implementing a laboratory QMS as stipulated in the international standard ISO/IEC 17025. One of the main critical requirements to be demonstrated by a laboratory as stated in this standard is participation in proficiency testing conducted by a third-party accredited agency. The organization that conducts proficiency testing is called a Proficiency Testing Provider. The international organization for standardization has stipulated the QMS to be implemented by such an organization in ISO/IEC 17043.

The five main advantages of participation in PT Schemes are as under:

  • Evaluation of the performance of laboratory for specific tests/calibrations;
  • Providing additional confidence to customers of the laboratory;
  • Identification of problems in laboratories and initiation of actions for improvement which, for example, may be related to inadequate test or measurement procedures, the effectiveness of staff training and supervision, or calibration of equipment;
  • Education of participating laboratories based on the outcomes of such comparisons;
  • Validation of uncertainty claims of laboratories;

The deficiencies in the self-organized ILC are as under:

  • Impartiality is not maintained as the organizer is also a participant;
  • Robust statistical techniques are not used in the performance evaluation;
  • Confidentiality of the participants is not maintained and consequently, there is a possibility of collusion between the participants and falsification of the results;
  • The number of participants is less in ILC (Around 5 or 6 only) and hence the uncertainty in the assigned value is too large and the outcome of ILC is not dependable;
  • Homogeneity and stability of the samples distributed is not ensured;
  • Handling, storage, and transport of PT items are not satisfactory and consequently. The integrity of the sample is compromised.

The competency of a laboratory to perform testing of any product can be ascertained through PT participation. The above-mentioned deficiencies are rectified in proficiency testing conducted by ISO/IEC 17043. Further, proficiency testing requires robust statistical methods to be used for

(i) Determination assigned value for each measurand or characteristic of the proficiency test item (i.e. sample), (ii) Determination of evaluation criteria such as Standard Deviation for Proficiency Assessment (SDPA), and (iii) Performance evaluation in terms of Z score or Z prime score, etc. All these requirements are stipulated comprehensively in the standard ISO 13528.
To meet the proficiency testing requirements of textile testing laboratories, BTRA has documented and implemented the QMS as per ISO/IEC 17043 and secured accreditation by NABL during 2018. This includes most of the conventional mechanical and chemical tests being performed by textile testing laboratories.
BTRA has added Analytical tests parameters like Banned Amine, Formaldehyde, and Metals to its PT Scope, which no one else in India does, to cater to the textile testing labs as well as chemical manufacturers. In 2020-2021, BTRA has conducted 2 PT programs as per ISO/IEC 17043 in chemical/mechanical testing, covering 12 chemical (with analytical) and 5 mechanical tests. Over 50 plus textile testing laboratories from different parts of the country as well as overseas have participated in these PT programs. We have received a good response from the laboratories as well as our reports were well accepted by the users.
