Each member body interested in a subject for which atechnicalcommitteehasbeenestablishedhastherighttoberepresented on that committee. International organizations, governmental and non- governmental, in liaison with iSO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 14269-3 was prepared by Technical Committee ISO/TC23， machines for agriculture and Tractors forestry and SubcommitteeSC2,Commontests. This first edition, along with the other parts of IsO 14269, cancels and replaces ISO 3737:1976, ISO 6097:1989 and ISO/TR 8953:1987, which have been technically revised. IsO 14269 consists of the following parts, under the general title Tractors and self-propelled machines for agriculture and forestry - Operator enclosure environment: Part 1: Vocabulary Part 2: Heating, ventilation and air-conditioning test method and performance Part 3: Determination of effect of solar heating Part4:Airfilterelementtestmethod Part 5: Pressurization system test method @ISO1997 All rights reserved.

This standard is applicable to tractors and self-propelled machines for agriculture and forestry when equipped with an operator enclosure. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this part of most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. environment Part 1: Vocabulary. 3 Definitions particularly relevant. 3.1 solar heating: Heating factor from the sun to be considered in determining air circulation and cooling definition 2.18] 3.2 solar radiant energy: Process by which solar heating is generated. [1SO 14269-1:1997, definition 2.19] 4 General 4.1 The intended result of this method is to record the radiant heat energy affecting an operator enclosure during tests of the air-conditioning system. 4.2 This method should be used in conjunction with the test given in IsO 14269-2:1997, Tractors and self- propelled machines for agriculture and forestry Operator enclosure environment Part 2: Heating, ventilation andair-conditioningtestmethodandperformance
