Foreword

GB/T 19933 "moving machinery cab environment" is divided into six sections.

--- Part 1. Terms and definitions;

--- Part 2. Air filter test method;

--- Part 3. Test methods for pressurization;

--- Part 4. heating, ventilation and air conditioning (HVAC) test method and performance;

--- Part 5. Test methods for windshield defrosting system;

--- Part 6. Determination of effect of solar heating.

This section GB/T 19933 Part 6.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 19933.6-2005 "moving machinery - Operator enclosure environment - Part 6. Measuring cab solar thermal effects set". This portion of the GB/T 19933.6-2005 compared, in addition to editorial changes outside the main technical changes are as follows.

--- Increased Chapter 2, "Normative references";

--- Increased Chapter 3, "Terms and Definitions";

--- Increase the Chapter 4, "General Provisions";

--- Adjustment and increased Chapter 5, "test equipment";

--- Modify the technical content.

This section uses the translation method identical with ISO 10263-6:2009 "moving machinery - Operator enclosure environment - Part 6. effect of solar heating Determination "(in English).
