Intergranular Corrosion Testing Glassware for ASTM A262 & ASTM G28 methods for Intergranular Corrosion Testing.
Intergranular corrosion is a term in reference to material degradation occurring along the grain boundaries of metallic materials that have been exposed within a corrosive environment.
A variety of ASTM methods are used to determine Intergranular corrosion and here at A M Glassware we have worked alongside key laboratory personal to manufacture glassware for several of these methods in particular the ASTM A262 & G28 methods.
ASTM A262 is a set of practices designed to detect susceptibility to intergranular corrosion of materials such as Stainless steel & Aluminium. It is often the request of certain manufacturers to have intergranular corrosion qualification tests carried out.
ASTM A262 consists of five Intergranular Corrosion Testing Methods (listed below) which involve the exposure of material specimens to a corrosive environment.
- The Oxalic Acid Test – Practice A
- The Strauss Test – Practice B
- The Huey Test – Practice C
- The Streicher Test – Practice E
- The Copper Sulfate Test – Practice F
ASTM G28 is a series a test methods used to determine susceptibility to intergranular corrosion in wrought, nickel-rich, chromium bearing alloys and consists of two methods.
- Method A, Ferric Sulfate-Sulfuric Acid Test
- Method B, Mixed Acid-Oxidizing Salt Test
