Theclassificationsystemdividesenvironmentalconditionsintogroupsbasedontheirseverityandfrequency.Eachgroupisassignedaspecificclassificationcode,whichindicatesthelevelofriskposedbythatcondition.

InthecaseofStorage,theclassificationsystemconsiderstemperature,humidity,lightexposure,andvibration/shockaspotentialenvironmentalfactors.Basedontheirseverityandfrequency,thesefactorsaregroupedintodifferentclasses,rangingfromClass1(nosignificanthazard)toClass4(highlyhazardous).

Class1correspondstoconditionsthataretypicallycomfortableformostproducts,withrelativelylowhumidityandtemperatures.Class2representsconditionsthatmaycausesomedegradationofmaterialsorminormechanicaldamage,butarenotconsideredhazardous.
