Elevated Temperature RGA Scans of Semitron ESD 480 Black PEEK
Used in ALIGO OSEM bodies.
The load consists of 25 blocks of Esd 480 PEEK, each 2 inch x 1 inch x 1-7/16 inch or 81.45 cm^2 per block and 2036 cm^2 for the RGA test.
Each A-OSEM body (D0901048-v4) has 78.91 cm^2 of ESD 480 PEEK surface area.
Notes and Changes:
At room temperature, the outgassing rates for A-OSEM bodies is as follows:
species AMU Torr-L/s/AOSEM body
hydrogen (H2) 2 7.0E-12
water (H2O) at 1000 hr max of 16, 17, 18 2.7E-11
air (N2) 28 5.6E-11
CO2 44 4.6E-10
hydrocarbons sum of 41, 43, 53, 55, 57 1.5E-11
