Foreword
This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives
for Standardization - Part 1: Rules for the Structure and Drafting of Standardizing Documents.
This document is Part 4 of GB/T 43407 Road Vehicles - Ergonomic Requirements for the
Driver’s Compartment in Low-floor Line-service Buses. GB/T 43407 has issued the following
parts:
---Part 1: General Description and Basic Requirements;
---Part 2: Visibility;
---Part 3: Information Devices and Controls;
---Part 4: Compartment Environment.
This document modifies and adopts ISO 16121-4:2011 Road Vehicles - Ergonomic
Requirements for the Driver’s Workplace in Line-service Buses - Part 4: Cabin Environment.
In comparison with ISO 16121-4:2011, the technical differences and the reasons for these
differences are as follows:
---The term “low-floor” and its definition are deleted (see 3.1 of ISO 16121-4:2011), so as
to avoid duplication of definitions;
---The term “efficiency or penetration” and its definition are deleted (see 3.3 of ISO 16121-
4:2011), so as to adapt to the requirements of Chinese standards;
---The term “time zero” and its definition are deleted (see 3.4 of ISO 16121-4:2011),
because it is not quoted in this document;
---The requirements for the heating system are modified, specific requirements for the
operating performance of the heating system are added (see Table 1), and the normative
reference of GB/T 12782 is added (see 4.2.1), so as to adapt to the technical conditions
of China and enhance the operability;
---The requirements for the cooling system are modified, specific requirements for the
operating performance of the cooling system are added (see Table 2), and the normative
reference of JT/T 216 is added (see 4.2.2), so as to adapt to the technical conditions of
China and enhance the operability;
---The normative reference of GB 11555 is used to replace SAE J381 (see 4.4.1), so as to
adapt to the technical conditions of China and enhance the operability;
---The normative reference of GB/T 24552 is added (see 4.4.1), so as to add the
requirements for the defrosting and demisting performance of electric buses;
