Jeff Moredock, at Sy-Klone International says the new ISO 23875 standard is an air quality standard for cab enclosures. It is currently a draft standard, and expected to be published at the beginning of 2021. It is designed to protect machine operators from harmful respirable particulates found outside of the cab in mining environments. By applying engineering controls to the cab, air quality testing can be conducted to determine air quality in the cab meets the requirements of the standard. This is important to protect operators as there is a high risk of them breathing in harmful particulates in many of the operating environments in which they are working. In addition to improving operator health, the new standard will provide a single, global standard for OEMs to follow. This will eliminate the burden of designing a machine cab to meet different standards in different parts of the world.
