ASTM WK95487

New Guide for Measurement of Gas Permeability in Graphite under Steady Flow

1. Scope

1.1 This guide covers the measurement of gas permeability of carbon and graphite by using a method based on the Darcy equation. The gas permeability can be estimated by using this method. 1.2 The gas permeability measurements for the method are at gas pressures up to 0.5 MPa, due to the specific method of specimen sealing.

Keywords

Darcy; coefficient; permeabiltiy

Rationale

This is a new guide for the measurement of gas permeability in graphite under steady flow. Gas permeability of graphite components is required to understand the coolant flow and potential oxidation of the components in gas-cooled nuclear reactors.
