1、 ANSI/ASABE S613-3 JUN2013 Tractors and self-propelled machinery for agriculture Air quality systems for cabs Part 3: Filters for environmental cab HVAC systems American Society of Agricultural and Biological Engineers ASABE is a professional and technical organization, of members worldwide, who are
2、 dedicated to advancement of engineering applicable to agricultural, food, and biological systems. ASABE Standards are consensus documents developed and adopted by the American Society of Agricultural and Biological Engineers to meet standardization needs within the scope of the Society; principally
3、 agricultural field equipment, farmstead equipment, structures, soil and water resource management, turf and landscape equipment, forest engineering, food and process engineering, electric power applications, plant and animal environment, and waste management. NOTE: ASABE Standards, Engineering Prac
4、tices, and Data are informational and advisory only. Their use by anyone engaged in industry or trade is entirely voluntary. The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance with
5、 applicable ordinances, laws and regulations. Prospective users are responsible for protecting themselves against liability for infringement of patents. ASABE Standards, Engineering Practices, and Data initially approved prior to the society name change in July of 2005 are designated as “ASAE“, rega
6、rdless of the revision approval date. Newly developed Standards, Engineering Practices and Data approved after July of 2005 are designated as “ASABE“. Standards designated as “ANSI“ are American National Standards as are all ISO adoptions published by ASABE. Adoption as an American National Standard
7、 requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by ASABE. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected in
8、terests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at a
9、ny time. Additionally, procedures of ASABE require that action be taken periodically to reaffirm, revise, or withdraw each standard.

11、ers for environmental cab HVAC systems Developed by the ASABE Environment within Ag Vehicle Enclosures subcommittee; Approved by the ASABE Power and Machinery Division as an ASABE standard June 2013; approved as an American Nation Standard August 2013. Keywords: Air quality, Cabs, Engineering contro
12、l, Environment, Filter, HVAC, Procedures, Safety, Terminology, Test, Tractor, Ventilation 1 Scope 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
13、 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 hazard
14、ous 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
15、system for reduction of application specific air-borne contaminants as part of an OHSMS as defined in part 1. Note: In this standard the term “filter“ will be used to signify the air purifying device. 2 Normative References The following referenced documents are indispensable for the application of

Record the time to breakthrough, time t min., or termination of the test. 4.11 Record pre
19、ssures, P1 and P2, and the mixture concentration at the end of the test. 4.12 Turn of all test items when the test is concluded and purge the test system with fresh air. Report the results for each filter tested. 5 Calculations 5.1 Rated service life 5.1.1 The service life of the air purifying devic

Time begins from first exposure and capture of a pesticide in the filtering device and continues even when the device is not directly exposed to pesticides in other operations. W is the to
21、tal weight of test agent sorbed during the qualification test, g; CFis the test agent challenge concentration, g/m3; Q is the flow rate through the air purifying device, m3/h; Rtis the test agent injection rate, 2.83 mL/min (4.5.2.6); T is the test time, in min (4.5.2.10); D is the test agent densit
