ISO 8655-4:2002 PDF Download

ISO 8655-4:2002 is a standard that specifies the specifications for dilutors, which are piston-operated volumetric apparatus used in analytical chemistry and laboratory applications to precisely dilute samples. The standard defines the metrological requirements, including the maximum allowable errors, for dilutors with particular sample uptake and diluent volume capabilities.

The standard applies to dilutors having sample uptake capacities ranging from 5 to 10 milliliters and diluent capacities ranging from 50 to 100 milliliters. These dilutors are designed to deliver the sample and diluent in a predetermined proportion and volume, resulting in accurate and exact dilutions.

Furthermore, the standard requires dilutors to be labeled with the manufacturer's name, model, and serial number, as well as the essential capacities and measurement ranges. This information is critical for users to guarantee proper diluator selection and use.
