GB/T 8094-2023Equipment for harvesting - Combine harvesters - Determination and designation of grain tank capacity and unloading device performance (English PDF)

foreword

This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents"

drafting:

This document replaces GB/T 8094-2005 "Determination of Grain Tank Capacity and Grain Unloading Mechanism Performance of Harvesting Machinery Combine Harvesters" and is in line with

Compared with GB/T 8094-2005, except for structural adjustment and editorial changes, the main technical changes are as follows:

a) The scope has been changed (see Chapter 1, Chapter 1 of the:2005 edition);

b) Added terms and definitions (see Chapter 3);

c) Added requirements for test prototypes (see 4:1);

d) Change "test conditions" to "test preparation" and change related content (see 4:2, 3:1 of the:2005 edition);

e) Changed the test procedure (see 4:3, 3:2 of the:2005 edition);

f) Changed the calculation method of the maximum grain unloading speed (see 5:1, 4:2 of the:2005 edition);

g) Changed the calculation method of grain unloading time (see 5:2, 4:3 of the:2005 edition);

h) Changed the calculation method of grain tank capacity (see 5:3, 4:1 of the:2005 edition);

i) The list of test report items has been changed (see Chapter 6, Chapter 5 of the:2005 edition):

This document is equivalent to ISO 5687:2018 "Determination of grain tank capacity and grain unloading mechanism performance of harvesting machinery combine harvesters":
