ARE YOU READY for the ISO 23875 Cabin Air Standard!

ARE YOU READY for the ISO 23875 Cabin Air Standard!

ISO 23875 is a new international standard for a consistent approach to designing, testing, operating, and maintaining the air-quality systems of operator enclosures.

Adoption of the requirements and test methods outlined in the standard protects personnel inside operator enclosures.

WATCH an exclusive overview of ISO 23875, presented by ISO Working Group Lead, Jeff Moredock, to learn about the standard's five key performance requirements, including:

  1. Defined levels of CO?
  2. Increased filtration efficiency requirements
  3. Fresh air and recirculated air system requirements
  4. Established cabin pressurisation levels
  5. Real-time operator cab monitoring requirements

Safety in mining operations is of concern to all involved in owning, developing, managing, and working in mining environments.

Routine mining activities can generate airborne particulates that may be hazardous to human health. Therefore, it is necessary to develop controls that limit the operator’s exposure to airborne particulate while operating equipment from within the operator enclosure. With the rise in the number of countries regulating air quality in mining, construction, and industrial environments, machine manufacturers and mine owners have become increasingly aware of the need for standard practices in the design and performance of operator enclosures.?

All operator enclosures, either on new machines or existing machines currently in operation, are expected to provide consistent air quality performance. The technical aspects of an operator enclosure are universal, as are the design and performance testing methods, and this new standard addresses the needs of fixed and mobile operator enclosures.

The ISO 23875 standard will place a greater emphasis on the air quality inside the cabin than previously addressed.

This means designers and operators will need to consider aspects of control of airborne contaminants such as dust but also address the effects of CO? (a product of human respiration) dilution in the cabin environment. This will allow for operator enclosures to perform at a level that provides sustained air quality, reducing concentrations of respirable particulate matter and carbon dioxide (CO?) that may be harmful to human health.

The design specifications are universal in their application and do not contemplate specific mining environments.

Sy-Klone’s RESPA? system keeps dust and debris outside of the operator's cabin. The system includes a pre-cleaner, pressuriser, high-efficiency filtration, and in-cabin monitoring system.

ISO 23875 differs from past standards because it is a lifecycle standard, addressing cabin air control systems from the time of design to the time that equipment arrives on site and throughout its operating life. ISO 23875 outlines specific engineering and ongoing testing to ensure compliance.

Trysome Auto Electrical Engineering , in partnership with Sy-Klone International, is well positioned to help mining companies meet ISO 23875 requirements. With over 30 years of experience, and over 100 patents in air filtration and pre-cleaning, Sy-Klone International creates industry-leading air filtration solutions for the most intensive, debris-laden work environments. Together, Trysome Auto Electrical Engineering and Sy-Klone International bring you world-leading air-quality and control systems for heavy-equipment cabins.

Sy-Klone’s RadialSHIELD? HEPA filters outperform the competition, delivering a higher filter efficiency while maintaining needed airflow levels – (ISO 35 H, H13) 99.95% efficient at the Most Penetrating Particle Size (MPPS) 63 nanometers including Covid-19 sized particles.

ISO 23875 requirements

  • Increased filter efficiency requirements: A filter that meets more stringent evaluation criteria, typically an ISO 15 E or higher efficiency or ISO 35 H HEPA filter, is required in ISO 23875-compliant cabins in mining.
  • Maximum allowable CO? level: Ambient CO? plus 400 parts per million
  • Fresh air and recirculation system requirements: Maximum respirable particulate matter concentration of less than 25 mg per cubic meter of air at the start/end of the decay test, with a maximum of 120 seconds delay time.
  • Established cabin pressurisation levels: Operator enclosures must maintain minimum pressurisation of greater than or equal to 20 Pa, even when the HVAC is turned off.
  • Real-time operator cabin monitoring: The monitor must include an audible alarm for CO? and pressurisation to alert the operator when levels go beyond the permissible threshold.
