Testing device for seal bodies
First Claim
1. Device for measuring the permeability of a fluid and/or vapor test medium through an annular seal gap and elastomeric seal bodies spanning the seal gap comprising:
- a container incorporating a recess for containing the test medium, the recess being completely covered and closed off by an imperforate lid by way of screws fastening the lid to the container, wherein the seal body is positionable between surfaces of an end face of the container and a face of the lid, both surfaces being placed opposed to each other to define said annular seal gap providing an escape path for the test medium, and lockable in position by way of the screws using a predetermined load force, and the test medium being measurable as said medium escapes to the exterior through the remaining material thickness of the seal body through said seal gap between the surfaces.

Abstract
A device for measuring the permeability of fluids and/or vapors through elastomeric seal bodies comprising a container incorporating a recess for holding a test medium, the recess being covered and closed off by a lid by way of screws fastening the lid to said container, wherein the seal body is positionable between the end face of the container and the face of the lid, both surfaces being places so as to face each other, and lockable in position by way of screws using a predetermined load force, and the test medium is measurable as it passes to the exterior through the remaining material thickness of the seal body through a seal gap between the front faces.

11. A method for testing the permeability of an elastomeric seal body while compressed between opposite sealing surfaces under a predetermined load, the method comprising the steps of:
-
providing a container having a recess and an upper annular sealing face; providing a lid having a lower annular sealing face and being constructed to completely close off the recess; disposing a test medium in the recess; disposing the seal body between the upper and lower annular sealing faces; fastening the lid to the container under a predetermined load and completely closing off the recess by elastically compressing the seal body between the upper and lower annular sealing faces and defining an annular seal gap between the upper and lower annular sealing faces providing an escape path for the test medium; and measuring the escape of the test medium as it escapes through the seal gap and through the seal body. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A seal permeability measuring assembly for measuring the permeability of a fluid and/or vapor test medium, comprising:
-
a container having a recess and an upper annular sealing face; the test medium disposed in said recess; a lid having a lower annular sealing face adapted to overlie said upper sealing face to define an annular seal gap between said faces and to completely close off said recess; an elastomeric seal body elastically compressed in said seal gap between said upper and lower sealing faces; and a measuring device in communication with said assembly to measure said test medium as said test medium escapes through said seal gap. - View Dependent Claims (19, 20)
