ISO 8490 – Modified Erichsen Cupping Test

Description

ISO 8490  – Metallic Materials — Sheet and strip — Modified Erichsen Cupping Test

ISO 8490 specifies a method for determining the ability of sheets and strips having a thickness from 0,2 up to 2 mm and a width of 90 mm or more to undergo plastic

deformation in stretch drawing

The test is referred to as the modified Erichsen cupping test as, in the test as originally introduced, no blank holder pressure was used but, in the interests of obtaining

greater consistency of results, this was changed.

*** Before conducting this ISO standard  , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
