Specifies essential geometric requirements for interchangeability for four series of joints for incorporation in laboratory glassware. Based on ISO 383.

This standard specifies the essential geometric requirements for interchangeability in relation to four series of conical ground glass joints (viz k2, k4, k6, k8) with ground surfaces for incorporation in laboratory glassware. The k6 series is preferred.
