Tractors and self-propelled machinery for agriculture - Air quality systems for cabs - Part 3: Filters for environmental cab HVAC systems
Published by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.orgASAE ANSI/ASABE S613-3.1 June 2018

This part of the S613 standard series is concerned with the generally accepted design principles and test procedures that define and qualify a filter for an HVAC system used in contaminated environments as part of an Occupational Health and Safety Management System (OHSMS). This document is intended to be a guide for engineers who are responsible for designs used in agricultural applications and for application specialists who are looking for a filter to be used when operating in a specific hazardous environment.
Filter performance specifications for the cab and HVAC system will be a primary consideration in this part of the standard. These performance specifications may be used by cab designers and filter manufacturers to develop air purification devices that can be used in a specific HVAC system for reduction of application specific air-borne contaminants as part of an OHSMS as defined in ANSI/ASABE S613-1.
This standard provides guidance for use of these systems and defines a way to test the level of protection provided, as defined by the OHSMS (See ANSI/ASABE S613-1 Tractors and self-propelled machinery for agriculture — Air quality systems for cabs — Terminology and overview). It is expected that other tests may provide cabs that are as well suited for this purpose; it is up to the user to demonstrate equivalency.
This standard is not intended to qualify cabs for use in extreme hazardous or oxygen depleted environments where a pressurized respirator or other high specification protection requirements are required and therefore are not covered by this standard.
Note: In this standard, the term “filter” will be used to signify the air purifying device.(Download PDF) (Export to EndNotes)
