| igus® Standard Carrier Material meets Class 1 Cleanroom Requirement | ||

In a series of test performed in the spring of 1998 by an independent engineering lab,
stock igus® Energy Chains® were proven to be withing Class 1 cleanroom limitations as set
forth by the Federal Standard 209E. The particulation test invloved a through-the-floor Class 1 cleanroom setup, measuring three separate cable carrier sections at >0.10, >0.20, >0.30, >0.50, >0.70 and >1.0 microns. Background counts run periodically throughout the process verified that the cleanroom conditions did not alter during testing. Each cable carrier section was measured for particulation at 15 different points along a 3-foot stroke, 20 inches/second linear apparatus, using a bend radius of 1.9 inches, simulating a common condition for handling systems and microchip production equipment. The cable carriers were put through three trial analyses to create an average. In each case, the standard E-Chain material Igumid G" , used for all the off-the-shelf Energy Chains® except "EZ-Chain" chains, fell well within Class 1 parameters. In addition to "Igumid G", the igus® material "Low Wear" blend for for abrasive environments and the blend for used for "EZ-Chain" series were tested under identical conditions. All igus® materials met Class 1 limits. Like most materials, higher wear can be expected at higher speeds. |
