GB/T 21154-2014Earth-moving machinery -- Methods of measuring the masses of whole machines, their equipment and components (English PDF)

Foreword

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

"Quality measurement methods earthmoving machinery machine, their equipment and components." This standard replaces GB/T 21154-2007, this standard Compared with GB/T 21154-2007, in addition to editorial changes outside the main technical changes are as follows.

--- Increasing the number of terms and definitions, delete a terms and definitions, modify the relevant terms and definitions (see Chapter 3, 2007 the first edition chapter 3);

--- Measurement methods "indirect measurement" to "accumulate Measurement" (see 3.3.2 and 54, 2007, version 3.3.2 and 5.4.);

--- Added "axis bridge load Measurement" (see 5.5);

--- Information about the quality of the measurement application examples (see Chapter 6);

--- Relevant provisions were modified and adjusted;

--- Deleted Appendix A (see 2007 edition of Appendix A).

This standard uses the translation method identical with ISO 6016:2008 "Quality Measurement party earthmoving machinery machine, their equipment and parts law".
