4 Basic requirements for inspection and test
4.1 Test load
4.1.1 The test load is a homogeneous cube with a mass equal to the rated lifting capacity Q of industrial trucks, with an error of ±1%, and a side length equal to 2 times the center distance D of the standard load (see Figures 1 and 2). The values of Q and D shall comply with the requirements of Annex A of GB/T 10827.1-2014.
4.1.2 In order to ensure that the side length of the test load is equal to 2 times the center distance of the standard load, it is allowed to make the test load into a cube with homogeneous periphery and hollow center, as shown in Figure 3.
4.1.3 The auxiliary test loads are 60%Q, 70%Q and 110%Q, with the load center distance unchanged, and its dimension is generally not specified on the premise of meeting the test requirements.

4.2 Instruments and gauges for inspection and test
4.2.1 The instruments and gauges for inspection and test shall be verified (calibrated) and be within the validity period. The accuracy of the instruments and gauges shall be selected according to the technical requirements of the products under test. Among them, the integrated testing device for industrial trucks safety monitoring system (hereinafter referred to as "integrated testing device") includes but is not limited to: weighing sensor, laser rangefinder, angle meter, tachometer, radar rangefinder, angle ruler (or protractor).
4.2.2 After the integrated testing device is installed at the relevant position of the industrial truck under test, it shall carry out communication and debugging with the industrial truck safety monitoring system (hereinafter referred to as "monitoring system"). See Annex A for the universal data acquisition protocol between the integrated testing device and the monitoring system.
