Calibration and quality control in the use of radionuclide calibrators
This International Standard specifies the techniques for calibration and usage of pressurised, well-type ionisation chambers for the assay of radionuclides. Such instruments are used to determine the activity, expressed in becquerel (Bq), of photon and some medium to high-energy beta emitting radionuclides.
This document provides the methods and tests for establishing and maintaining acceptable…
Molecular biomarker analysis — General guidelines for single-laboratory validation of qualitative re...
This document describes the performance characteristics and minimum performance criteria which should be taken into account when conducting a single-laboratory validation study for qualitative (binary) real-time polymerase chain reaction (PCR) methods applied for the detection of specific DNA sequences present in foods.
The protocol was developed for qualitative real-time PCR methods for the…
Solar energy — Calibration of a pyranometer using a pyrheliometer
Its use is mandatory for the calibration of secondary standard pyranometers according to ISO 9060, and is recommended for the calibration of pyranometers which are used as reference instruments in comparisons. Is intended for use by test institutions or test laboratories equipped with well-maintained pyrheliometers and is applicable to all pyranometers. The object is to promote the uniform…
