ÖNORM EN 13311-3

This European Standard specifies performance criteria for glass pressure vessels used in biotechnological processes with respect to the potential hazards to the worker and the environment from microorganisms in use. This European Standard applies where the intended use of glass pressure vessels includes hazardous or potentially hazardous microorganisms used in biotechnological processes or where exposure of the worker or the environment to such microorganisms is restricted for reasons of safety. This European Standard also applies to pressure vessels used in biotechnological processes that are made of other brittle materials such as acrylate polymers or porcelain. This European Standard does not apply to small glass parts which form an integral part of equipment such as sight glasses. This European Standard should be used in conjunction with other relevant standards when substantial parts of glass or from other brittle materials are present.
