1、 ANSI/ASABE S613-3.1 JUN2018 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 a

2、re 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; principal

3、ly 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 Pr

The ASABE assumes no responsibility for results attributable to the application of ASABE Standards, Engineering Practices, and Data. Conformity does not ensure compliance wi

5、th 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”, re

6、gardless 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 Standa

7、rd 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

8、interests. 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 CAUTION NOTICE: ASABE and ANSI standards may be revised or withdrawn at

9、 any time. Additionally, procedures of ASABE require that action be taken periodically to reaffirm, revise, or withdraw each standard.

11、 Part 3: Filters 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; revised June 2018.

12、uality, Cabs, Engineering control, Environment, Filters, HVAC, Procedures, Safety, Terminology, Test, Tractors, 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

13、 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 w

14、hen 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 th

15、at 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

16、 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 t

17、o 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 purify

18、ing device. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies unless noted.

A.4.9 Start the recorder to monitor the response analyzer in the downstream location. A.4.10 Continue testing until the breakthrough concentration reaches 72 7.2 mg/m3(20 2

21、 ppm) or to 30 minutes if no breakthrough occurs. Record the time to breakthrough, time t min., or termination of the test. A.4.11 Record pressures, P1 and P2, and the mixture concentration at the end of the test. A.4.12 Turn off all test items when the test is concluded and purge the test system wi

W is the total weight of test agent sorbed during the qualification test, g; CF is the test agent challenge concentration, g/m3; Q is the flow rate through the

24、air purifying device, m3/h; R is the test agent injection rate, 2.83 mL/min (A.4.4); t is the test time, in min (A.4.10); D is the test agent density, 0.902 g/mL (A.4.4). A.5.1.2 The service life of the filter shall be estimated with a safety factor of 10. Tests recording less than 100 g/m3shall hav

25、e T (time) calculated on a minimum value of 100 g/m3, which represents very high pesticide concentrations measured in agricultural applications. Concentrations exceeding 100 g/m3shall have T calculated on measured values. A.5.1.3 The recommended service life shall not exceed T or one use season, whi

A.6.3 Record the pressure drop across the filter at the beginning (A.4.6) and end of test (A.4.11). A.6.4 Report the manufacturers part number, lot number, and any o

28、ther number or designation that will identify the device. A.6.5 Report the laboratory, test date, and laboratory test reference numbers. The test shall be signed by a certified laboratory technician. A.7 Filter Identification and Instructions A.7.1 Filters qualified by these tests shall include the

31、ded shall include: a) Date of installation; b) A check list of seals and surfaces to inspect during installation (cab and filter); c) Equipment hour meter reading when installed. Filter life is measured for the total time the filter is installed in a cab from the first hour meter reading until remov
