GB/T 33575-2017Freight containers -- Electronic seals -- Environmental characteristics (English PDF)

4.1 General requirements

This standard should be used with other parts of ISO 18185.

This standard applies to all electronic box covers for containers covered by the following standards. ISO 668, ISO 1496-1, ISO 1496-2,

ISO 1496-3, ISO 1496-4, ISO 1496-5, ISO 830. As long as appropriate and feasible, this standard also applies to the above standard does not cover the freight

container.

Container electronic box seals are typically used in harsh environments for shipping, rail and road transport. Sand, dust, salt spray, grease, snow, ice and dust

The scale will cover the surface of the label and sensing equipment. Lifting and transport operations will be subject to physical shock and vibration.

Containers are circulating around the world, and ambient temperatures often cause significant temperature changes and may be exposed to sunlight and ultraviolet light for a long time

Line down. Container electronic box seal should be able to work in its surface temperature between -40 degrees C ~ 70 degrees C between the normal work, and in the -51 degrees C ~

85 degrees C between the intact storage of data. The electronic box seal shall be in a harsh environmental condition covered by the specified test method (at least)

Enough to work and ensure the integrity of the stored data.

The system should be able to function properly in the typical electromagnetic environment of the transport equipment. The electronic box seal should be able to peak at an electric field intensity of 60 s

Value of 50V/m environment, as well as the normal work of the ship-borne radar and other equipment issued by the RF source and other conditions to work and ensure that

The integrity of the data.

4.2 low temperature

At low -40 ° C, the electronic box should be able to work normally. At a minimum temperature of -51 ° C, exposed to a daily environment for 24 h

After 60 days of storage, the label should still work properly. The test shall be carried out in accordance with IEC 60068-2-1 (MIL-STD-810F, method 502.4).

4.3 high temperature

The electronic box seal shall continue to operate normally after a circulating temperature of 70 ° C to 38 ° C. At a minimum temperature of 85 ° C per day

Exposure 12h ~ 15h environment storage 60 days (ISO 18185-2 specified electronic box closed the shortest use of life), the electronic box should still be sealed

normal work. The test shall be carried out in accordance with IEC 60068-2-2 (MIL-STD-810F, method 501.4).

4.4 Mechanical shock

The electronic box seal should still function normally during the 30 h mechanical shock process and after the impact of the half sine pulse for 11 s. test

Should be completed according to IEC 60068-2-2 (MIL-STD-810F, method 516.5).

4.5 random vibration

The electronic box is sealed between -40 ° C and 70 ° C and is subjected to a random vibration of 3 g in each axial direction and after vibration

Can work properly. The test shall be carried out in accordance with IEC 60068-2-53 (MIL-STD-810F, method 514.5).

4.6 Humidity

The electronic box seal should still function normally after being in a 95% non-condensing humidity environment. The test shall be in accordance with IEC 60068-2-53

(MIL-STD-810F, method 507.4).

4.7 rain and snow

Electronic box sealed in the rain and snow and after the time, can work properly. The label is submerged under 1m deep saline and afterwards

normal work. The test shall be carried out in accordance with IEC 60068-2-18 (MIL-STD-810F, method 506.4/512.4).

4.8 salt spray

The electronic box should still function normally when it is subjected to salt spray. The test shall be carried out in accordance with IEC 60068-2-11 (MIL-STD-810F,

Method 509.4) is completed.

4.9 drop

The electronic box seal can protect the equipment from damage in a test environment that falls from a height of 3.3m to the surface of concrete and steel. Test period

And after the test equipment can be reliable, fully operational. The test shall be in accordance with the method specified in IEC 60068-2-31 and IEC 60068-2-32

The drop height and impact surface are defined by this standard.

4.10 dust

The electronic box seal should still work properly after exposure to sand and dust. The test shall be carried out in accordance with IEC 60068-2-68 (MIL-STD-

810F, Method 510.4).

4.11 Electromagnetic environment

In the container field and the ship may exist in the electromagnetic environment, the label should be able to work properly. Tag in the field strong peak up to 50V/m,

Time for 60s, can still survive and maintain the integrity of the stored data. The label will survive after 25kV electrostatic discharge

Keep the integrity of the stored data.
