Standard Test Method for Determining Argon Concentration in Sealed Insulating Glass Units Using Spark Emission Spectroscopy

Importancia y uso:

5.1 This test method is intended to provide a means for determining the concentration of argon in sealed insulating glass units under controlled conditions in compliance with the apparatus manufacturer's instructions.

5.2 This is a non-destructive test method in that the edge seal of the test specimen is not breached in order to determine the argon gas concentration. However, damage to some glass coatings on the inner surfaces of the glass can occur.

5.3 This test method has been developed based on data collected in a controlled laboratory environment.

5.4 The device shall be used to determine the argon gas concentration in insulating glass units in a controlled laboratory environment. Refer to 12.3.

5.5 This test method may be used to determine the argon gas concentration before, during, or after the insulating glass unit is subjected to durability tests.

5.6 The accuracy of the test method is dependent upon the accuracy of the Spark Emission Spectroscope. When the concentration of the argon being measured is below certain levels, this test method is not applicable. See the spectroscope manufacturer’s literature for recommended levels of accuracy of a given model.
