4.4 Environmental test

4.4.1 The product shall be tested for temperature, humidity, and free drop in accordance with JY 0213-1994 Section 3.1, and shall be subjected to a drop test in an unpackaged state.

4.4.2 The drop height of the drop test in the non-packed state shall be 1 m, and the drop surface shall be the largest surface of the model outline.

If there is a stand, it should not be included.

5.1 Relevant dimensions

Measured with a steel ruler with a division value of 1 mm.

5.2 Anatomy, appearance and workmanship

Sensory test.

5.3 Environmental test

5.3.1 Temperature, humidity and free fall test According to JY 0213-1994 Section 4.1, 4.2, 4.6.

5.3.2 Drop test in unpacked state. Lay a wooden board with a thickness of 20mm ± 3mm on the cement floor. The board should be rigid with the cement floor contact. During the test, the model's falling surface is downward, and it will fall freely from a height of 1m. Once tested, it shall meet 4.4.2.

6.1 Inspection classification

Product inspection is divided into factory inspection, type inspection and quality supervision inspection.
