Validation of Metrological Software

Working Group 8.54

Profile

The working group is dealing with validations of complex software products in the domain of metrology. Especially, the increasing number of special validations of software programs supporting the GUM (Guide to the expression of uncertainty in measurement) is provided for. A main task is the development and application of the required testing environment and the continuous advancement and maintenance of the environment.

The current revision of ISO/IEC 17025 is reinforcing the importance of software validations in PTB laboratories. In this regard, the working group is performing supporting and consulting services for PTB laboratories in the scope of software validations as part of quality audits concerning ISO/IEC 17025.

Further tasks are:

  • Provide advice for working group 8.51 (Metrological Software),
  • Provide support for department Q.5 (Technical Cooperation).
  • Representation of PTB in DIN standardisation committees (Software Engineering, Health Informatics),
  • Performing assessments/audits in favour DAkkS (German Accreditation Body) and other European accreditation bodies (subject area Software Engineering).

Research/Development

The working group is developing methods and practicable procedures for the validation of software products implementing or partially supporting the GUM (Guide to the expression of uncertainty in measurement). The compiled procedures are assimilated in an automated testing environment. Major topics of the work are the derivation and analysis of appropriate software requirements. In order to provide support for software manufacturers before the development of GUM implementing software products, a guideline regarding the correct and GUM compliant implementation of such software products is elaborated.

Services

The working group provides supporting services for manufacturers of software products implementing the GUM (Guide to the expression of uncertainty in measurement). The development as well as the validation of such software programs is supported.
In the scope of quality audits related to ISO/IEC 17025, the working group supports the audit processes of PTB laboratories concerning the increasing importance of software applied in the laboratories.
The working group 8.54 is performing supporting and consulting services for the working group 8.51 (Metrological Software) and for the department Q.5 (Technical Cooperation). Furthermore, the group provides assessors for DAkkS (German Accreditation Body) and other European accreditation bodies (subject area Software Engineering).
