The purpose of the standard DIN 55473 of Auxiliary means of packaging and MIL-D-3464 is to create a standard for adsorptive desiccants in bags, like clay, silica gel or alumina gel.
The industrial standard DIN 55473 and MIL-D-3464 provides criteria for the evaluation of the efficiency of desiccant bags and states that the desiccants shall not be deliquesced to liquid. The standard also defines what a “desiccant unit” is for a desiccant based on the amount of water it can adsorb.
As we explain in our Insight “Silica gel desiccant for moisture absorption: things you need to know”, ContDry desiccants are made of calcium chloride and reduce the moisture available in the environment via absorption. ContDry desiccants are not adsorptive desiccants and therefore, the standards DIN 55473 and MIL-D-3464 does not apply to our desiccant bags.
