GB/T 19933.2-2014Earth-moving machinery -- Operator enclosure environment -- Part 2: Air filter element test method (English PDF)

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 2.

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

This Part replaces GB/T 19933.2-2005 "moving machinery - Part 2 cab environment. air filter test." Headquarters Points compared with the GB/T 19933.2-2005, in addition to editorial changes outside the main technical changes are as follows.

--- Chapter 2, "Normative references" added the appropriate reference standard (see Chapter 2, Section 2 of the 2005 edition);

--- Delete the text in the table (see the 2005 edition of the Table 1, Table 2 and Table 3);

--- Original 1 modifications are divided into Figures 1 and 2 (see Figures 1 and 2, 2005 Figure 1);

--- Added Appendix B "alternative air filter performance evaluation." this section uses the translation method identical with ISO 10263-2:2009 "moving machinery - Operator enclosure environment - Part 2. Air filter test Test method "(in English).

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

--- GB/T 19933.1-2014 moving machinery - Operator enclosure environment - Part 1. Terms and definitions (ISO 10263-1:2009, IDT).
