A constant temperature and humidity laboratory uses specialized equipment and techniques to maintain indoor conditions at standard atmospheric levels for temperature and humidity control and testing purposes. This type of laboratory serves as essential infrastructure for quality assurance in both manufacturing facilities and product inspection in the distribution sector. Constant temperature and humidity labs are widely utilized in industries such as cotton spinning, wool processing, chemical fibers, paper production, tobacco manufacturing, and quality control departments. These labs ensure that textile, textile raw materials, paper products, cardboard, and other commodities are inspected under standardized environmental conditions. For example, the standard atmosphere for inspecting textiles and their raw materials complies with ISO139 and GB6529 standards, maintaining a temperature of 20±2°C and relative humidity of 65%±2%. Meanwhile, the standard atmosphere for examining paper, cardboard, and similar materials follows ISO187 and GB10739 standards, with temperatures set at 23±1°C and relative humidity at 50%±2%. Beyond these standard conditions, there are specialized laboratories designed for extreme environments, including low temperatures between 5-18°C, high temperatures ranging from 30-80°C, low humidity below 40% RH, and high humidity above 80% RH.
Constant temperature and humidity labs play a critical role across various industries. Here are some examples of how different sectors apply specific temperature and humidity standards:
| Sub-option | Papermaking | Textiles | Plastics | Coatings |
| --- | --- | --- | --- | --- |
| Temperature (°C) | 23±1 | 20±1 | 20±1 | 23±2 |
| Relative Humidity (%) | 50±2 | 65±2 | 50±3 | 50±5 |
| Air Changes per Hour | 15~30 | 15~30 | 15~30 | 15~30 |
| Airflow Velocity (m/s) | ≤0.3 | ≤0.25 | ≤0.3 | ≤0.3 |
| Fresh Air Supply (m²/person) | ≥0.5 | ≥0.5 | ≥0.5 | ≥0.5 |
| Noise Level (dB) | ≤55 | ≤55 | ≤55 | ≤55 |
| National Standards | GB10739 | GB6529 | GB/T2918 | GB9278 |
| International Standards | ISO187 | ISO139 | ISO291 | ISO3270 |
These standards help ensure consistency and reliability in product quality across different industries. For instance, a textile manufacturer might use a constant temperature and humidity lab to verify the moisture content of fibers under controlled conditions, while a pharmaceutical company could employ a cryogenic lab to preserve biological samples at optimal temperatures.
