ISO/IEC 17025

On 4 april 2018 CALLAB Magazine published my contribution on pipette calibration. 

This paper discusses the calibration of pipette, with particular attention to the type that is used and calibrated most frequently. This is the so-called air-displacement pipette, single channel, adjustable volume pipet. The new ISO/IEC 17025, published November 2017, demands more attention to the agreement of the calibration procedure with the customer. The paper describes points that need to be agreed with the customer and calibration by the gravimetric method (weighing). The alternative calorimetric method (ISO 8655-7) is not described in this paper. Read the full article (PDF)

The Final Draft International Standard of ISO / IEC 17025 has been approved. Here are a few points for your attention.

 World Metrology Day 2017

The theme for World Metrology Day 2017 is Measurements for transport. This theme was chosen because transport plays such a key role in the modern world. We not only move ourselves, but also the food we eat, the clothes we wear, the goods we use and rely on, not forgetting the raw materials they are made from. Doing so safely, efficiently and with minimal environmental impact requires an astonishing range of measurements.
