Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents". Drafting.

This document supersedes GB/T 20315-2006 "Road Construction and Maintenance Equipment - Terminology and Commercial Specifications for Road Milling Machines" and is consistent with... Compared with GB/T 20315-2006, apart from structural adjustments and editorial changes, the main technical changes are as follows.

a) The definitions of the terms "road milling machine," "road milling machine chassis," and "working quality" have been changed (see 3.1, 3.2, and 3.6, 2006 edition). (2.1, 2.2 and 2.6)

b) Change the terms "milling device," "leveling device," and "collecting and unloading device" to "milling system," "leveling system," and "collecting and unloading device," respectively.

The definition of "material conveying system" has been changed (see 3.3-3.5, 2.3-2.5 in the 2006 edition);

c) The "Overview" section for road milling machines has been modified (see 4.1, 3.1 of the 2006 version);

d) The relevant provisions for tool arrangement, leveling, and milling depth control systems have been modified (see 4.2.4 and 4.2.5, and 3.2.4 in the 2006 edition). and 3.2.5);

e) The relevant provisions regarding other mass characteristics, engine characteristics, transmission characteristics, and driving position in the mass characteristics section have been changed (see 5.1.3 to 5.1.6). (Versions 4.1.3 to 4.1.6 of the 2006 edition)

f) Change "Driving Position" to "Steering Type" (see 5.1.6, 4.1.6 in the 2006 version);

g) The units of flow rate for liquid tanks and water pumps have been changed (see 5.1.8, 5.3, and 4.1.8 and 4.3 in the 2006 edition).

This document is equivalent to ISO 15645:2018, "Road construction and maintenance equipment - Road milling machines - Terminology and commercial specifications".
