Humidity Standards for Distribution Boxes
The ASTM D4332 standard is an essential guideline for conditioning containers, packaging, or packaging components for testing purposes. This practice is crucial because packaging materials, especially those made of cellulose, are sensitive to variations in temperature and relative. Temperature is specified in °Kelvin, abbreviated to K or °Celsius, abbreviated to °C: Humidity is described in terms of absolute humidity AH and relative humidity RH. The absolute humidity is the quantity (mass) of water vapor per unit volume of air [m³]. Relative humidity is specified as a. Environmental conditioning tests per ASTM D4332 are designed to evaluate standard and special conditioning environments that can be used to simulate the field conditions that a package or container may be exposed to during shipment or storage. Therefore, the package should be placed and kept in a specified atmosphere. The ability to custom design corrugated packaging for specific use underlies its versatility and performance in a wide variety of product and distribution scenarios.
