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 1.

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

This Part replaces GB/T 19933.1-2005 "moving machinery - Operator enclosure environment - Part 1. General and definitions." This portion GB/T 19933.1-2005 compared, in addition to editorial changes outside the main technical changes are as follows.

--- Standard name changed to "moving machinery - Operator enclosure environment - Part 1. Terms and Definitions";

--- Increasing the normative references (see Chapter 2, Chapter 2, 2005);

--- Increased and remove some of the terms and definitions (see Chapter 3, Chapter 3, 2005);

--- Increase the Chapter 4, "the abbreviation" (see Chapter 4).

This section uses the translation method identical with ISO 10263-1:2009 "moving machinery - Operator enclosure environment - Part 1. Terms and definitions" (In English).

Consistency correspondence between this part of international documents and normative references of our files are as follows.
