What is ISO 23506 about?
ISO 23506 discusses airborne water-immiscible mineral oil droplets and vapour. ISO 23506 describes the Fourier — Transform infrared spectroscopy method. Fourier — Transform infrared spectroscopy method quantifies the absolute exposure to mineral oil vapours and droplets, within a concentration range from 0,5 mg/m3 to 125 mg/m3, in the inhalable fraction of the workplace air.
ISO 23506 contains comprehensive information and instructions on the equipment and chemicals to be used. ISO 23506 is applicable for water-soluble oils and metalworking fluids.
The method described in ISO 23506 has been validated by the provisions of EN 13936 and ISO 20581 and has an expanded measurement uncertainty in the region of 20 % to 30 % within the measurement range stated.
Who is ISO 23506 for?
ISO 23506 on workplace air is useful for:
- Crude oil processing unit
- Oil refineries
- Air quality testing laboratories
- Chemical scientists
- Quality control personnel
- Health and safety inspectors
Why should you use ISO 23506?
Mineral oils are by-products of the distillation of crude oil. ISO 23506 describes the Fourier — Transform infrared spectroscopy method that is intended to support swift, cost-effective, and straightforward quantification of the concentration of mineral oil in many samples.
The Fourier — Transform infrared spectroscopy method described ISO 23506 was validated with these parameters for a GGP sampler. The Gesamtstaub-Gas-Probenahme (GGP) sampling system enables both droplets and vapours to be collected but any other personal sampler capable of collecting the inhalable droplets and vapours can be used simultaneously. A glass fibre filter is used to collect the droplets. A downstream sampling tube containing polymer resin is used to collect the vapours and more volatile components in the mineral oil. Using ISO 23506 lets you monitor the quality of workplace air
