1. Special requirements of special laboratories should be considered when determining the area of land use, such as some laboratories should be well grounded separately, and the grounding end should be far away from buildings; acoustic laboratories should be built separately to keep away from vibration; and high voltage laboratories should be built separately to ensure safe high voltage discharge distance.

2. In general, the classification of conventional, inorganic, organic and biological laboratories should be considered in the layout of light industrial products laboratories. At the same time, the laboratories and offices should be separated reasonably.

3. In determining the land area, the reserved area for later development should be considered. With the rapid development of the industry, testing projects and testing equipment are constantly updated and increased. In order to better meet the testing needs, sufficient space should be reserved for later construction in the early planning stage.
