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.

Claims

1. Device for measuring the permeability of fluids and/or vapors through elastomeric seal bodies comprising:

a container incorporating a recess for containing a test medium, the recess being covered and closed off by a lid by way of screws fastening the lid to the container, wherein the seal body is positionable between surfaces of end face and of the container and a face of the lid, both surfaces being placed opposed to each other, and lockable in position by way of the screws using a predetermined load force, and the test medium being measurable as it passes to the exterior through the remaining material thickness of the seal body through a seal gap between the faces.

2. Device as claimed in claim 1, wherein at least one of the surfaces is constructed with a non-planar contour.

3. Device as claimed in claim 1, wherein at least one of the surfaces has a groove corresponding to an installed condition in an operating state of the seal body.

4. Device as claimed in claim 1, wherein the screws comprise hexagon socket-type screws, in length not exceeding the outer border edge of the lid when the seal body is in the locked condition.

5. Device as claimed in one of claim 1, wherein the test of the permeability of a fluid and/or a vapor and/or gases through the seal gap is carried out by qualitative measurement of the weight reduction of the test medium.

6. Device as claimed claim 1, wherein the surfaces of the respective faces corresponds in contour and roughness to the face surface of the seal body in its installation state.

7. Device as claimed in claim 1, wherein the container and/or the lid are constructed of aluminum material.

8. Device as claimed in claim 1, wherein the container and/or the lid are constructed of synthetic material.

9. Device as claimed in claim 1, wherein the container and/or the lid are of cylindrical section.

10. Device as claimed in claim 1, wherein the measurement of permeability of a fluid and/or vapor and/or gases takes place under the influence of temperature.
