Overall Glove Box Main Chamber Leak Test
The Protector Controlled Atmosphere Glove Box has been tested with an oxygen
monitor detecting oxygen levels as low as 0.1 ppm; the rate of increase in oxygen
over time was determined in accordance with the ISO 10648-2 oxygen leak decay
test method. The results validate that the Protector Controlled Atmosphere Glove
Box meets Class 1 conditions for controlled atmosphere chambers. Figure 3-9 and
3-10 show test results of the oxygen permeation or oxygen level increase as a
function of time. Per ISO specifications, Class 1 controlled atmosphere chambers
-4
have a specified hourly leak rate of less than 5 x 10 (< 1.67 ppm/min) per Table 3-
1 listed at the end of Chapter 3 with performance results summarized in Chapter 1.
