Many industrial products are exposed to several atmospherical agents in addition to the well-known temperature, humidity and corrosion. Very high degradation phenomena are caused by sand, dust and rain. In particular, many electrical components have to be permanently water- tight, as they must work reliably even under the most adverse weather conditions. Test a wide variety of test specimens as to their tightness. IP test chambers for environmental simulation product testing meet with IEC 60529 IP code test.
