Standards Development
This part of ISO 8655 specifies requirements for user training and competence, as well as POVA performance tolerances and testing to ensure fitness for its intended use. This standard also provides user guidance regarding the selection of POVA (including exchangeable parts) and best practices for its use.
NOTE 1 General requirements and definitions of terms for piston-operated volumetric apparatus are given in ISO 8655-1. For the metrological requirements, maximum permissible errors, requirements for marking and information to be provided for users for piston-operated volumetric apparatus, see ISO 8655-2 for pipettes, see ISO 8655-3 for burettes, see ISO 8655-4 for dilutors, see ISO 8655-5 for dispensers, and see ISO 8655-9 for manually operated precision laboratory syringes. The gravimetric reference measurement procedure for the determination of volume is given in ISO 8655-6. The photometric reference measurement procedure for the determination of volume is given in ISO 8655- 8.
Alternative test methods for the determination of volume are described in ISO 8655-7.
During the revision and development of the ISO 8655 series of standards (ISO/AWI 8655-1 to -9), members of the ISO/TC48/WG04 recognized the need for a standard addressing standardized user training and guidance on best practices, particularly for the use of handheld pipettes. Further, the need was recognized for user guidance on establishing appropriate calibration and test programs (frequency, tolerances, number of replicates, etc), as well as on selecting the most appropriate POVA (Piston- Operated Volumetric Apparatus) for the intended use.
Companies and institutes in most member countries of this TC and WG04 have already been administering user training on best practices in pipetting. Since user technique is the biggest factor in pipetting errors, laboratories have been increasingly focusing on professional user training to achieve consistent and comparable laboratory results. Yet, there is currently no standard or guideline for such training and competence assessment. The proposed Part 10 of the ISO 8655 series will fill this void and provide requirements on user training and competence, as well as requirements for determining test specifications/programs for POVA.
Detailed guidance on pipetting technique will benefit any organization and laboratory using pipettes in their work. Many working group members consider this future ISO standard of high value to any enduser of POVA, organizations who seek to train their laboratory employees and/or set up test or calibration programs for their POVA, test house employees, as well as service organizations offering training to laboratories.
