Fig. 3: Timeline showing the development and acceptance of the most commonly used glass durability tests.
From: Forty years of durability assessment of nuclear waste glass by standard methods

Colours highlight tests that are historically linked; blue: static tests derived from original MCC tests, pink: series of tests that aim to measure the forward rate, orange: tests using vapour. Other colours relate to stand-alone tests that were either developed for another purpose (i.e., not for general application to glass) or imported from another regulatory framework.
