IEC 60068 Rapid Temperature Change Environmental Test Chambers
Complied Standards & Clauses
This rapid temperature change test chamber is designed and
manufactured according to IEC60068-2-1, IEC60068-2-2, IEC60068-2-78
and IEC60068-2-30.
Equipment Overview
It is used to process cold, heat, humidity and dryness testing of raw materials and devices such as Parts and materials for electronic appliances, food, automobiles, rubber and plastic materials, metals and other products, such as optical fiber, LCD, crystal, inductor, PCB, battery, computer, mobile phone, rubber, plastic, etc. The purpose is to confirm the reliability of storage, transportation and use of products under high and low temperature rapid alternating humid heat environment.
