For the purpose of this document, the terms and definitions given in GB/T 3730.1, GB/T 4780, and GB/T 12673 as well as the following apply.
3.1
luggage compartment
space in a vehicle body for luggage
[Source: GB/T 4780-2020, 4.2.6]
3.2
reference volume of luggage compartment
maximum sum of the volumes of the unit modules placed within the measurement boundary of a luggage compartment
Note 1: The luggage compartment whose volume is to be measured may be a front luggage compartment, a rear luggage compartment through to the passenger compartment, a rear luggage compartment not through to the passenger compartment, or a concealed enclosed luggage compartment.
Note 2: The volume unit is liter (L) or cubic decimeter (dm3).
3.3
unit module
cuboid for measuring the volume of a luggage compartment that has standardized dimensions and is sufficiently rigid to resist deformation
3.4
front luggage compartment
space for storage designed to be located in the powertrain compartment in the front of a vehicle
3.5
rear luggage compartment not through to the passenger compartment
rear space for storage not through to the passenger compartment (with the luggage compartment partition fixed and undetachable)
Note: The volume of a rear concealed enclosed luggage compartment is included in that of the rear luggage compartment not through to the passenger compartment
3.6
rear luggage compartment through to the passenger compartment
rear space for storage through to the passenger compartment (with the luggage compartment partition detachable, foldable and retractable)
Note: The volume of a rear concealed enclosed luggage compartment is included in that of the rear luggage compartment through to the passenger compartment
4 Unit module
Each unit module is a cuboid, with the fillet radius of each edge not greater than 10mm, while its dimension error shall not exceed ±1mm. Each unit module shall be sufficiently rigid to resist deformation, with its dimensions as specified in Table 1.
