ISO 14461-1|IDF 169-1:2005 describes a procedure for testing the performance of the colony-count technique within a laboratory by establishing the within-laboratory variability of its technique and identifying those steps that are associated with excessive variability. The procedure is also suitable for checking the proper observance of Good Laboratory Practice (GLP), which may be a prerequisite…

ISO 140-11:2005 specifies methods for measuring the acoustic properties of floor coverings from the viewpoint of reducing impact sound transmission. The purpose of ISO 140-11:2005 is to establish a method for determining the impact sound insulation of a floor covering under standard test conditions. The test is limited to the specification of procedures for the physical measurement of sound…

ISO/IEC 17025:2005 specifies the general requirements for the competence to carry out tests and/or calibrations, including sampling. It covers testing and calibration performed using standard methods, non-standard methods, and laboratory-developed methods. It is applicable to all organizations performing tests and/or calibrations. These include, for example, first-, second- and third-party…

Describes a small-scale laboratory procedure for determining the comparative burning characteristics of tubular polymeric materials. A flame is applied to test specimens held in a vertical position, supported by a wire or mandrel. Upon removal of the test flame, the extinguishing times and the burning characteristics are determined. This test method can be used to compare the burning…

ISO 4788:2005 specifies dimensions, material and constructional and metrological requirements of graduated measuring cylinders of tall form (Type 1a and Type 1b) and of squat form (Type 2). All types are suitable for general laboratory use. The specifications in ISO 4788:2005 are in conformity with the principles of design and construction of volumetric glassware given in ISO 384.

ISO 4094:2005 provides rules for the nomination and appointment of standardizing and authorized laboratories under the jurisdiction of ISO/TC 6, or one of its subcommittees, with the aim of establishing and maintaining the reference standards and distributing the transfer standards required to achieve interlaboratory agreement in the results of a test method specified in an International Standard…

ISO 18437-2:2005 defines a resonance method for determining from laboratory measurements the dynamic mechanical properties of the resilient materials used in vibration isolators. It is applicable to shock and vibration systems operating from a fraction of a hertz to about 20 kHz. ISO 18437-2:2005 is applicable to resilient materials that are used in vibration isolators in order to reduce --…

ISO 18437-3:2005 defines a cantilever shear beam method for determining from laboratory measurements the dynamic mechanical properties of the resilient materials used in vibration isolators. Common errors due to clamping the specimen are avoided by using fixed ends so there is no rotational motion of the beam at its ends. This part of ISO 18437 is applicable to shock and vibration systems…

This International Standard provides metrological and construction requirements for an internationally acceptable series of burettes, suitable for general laboratory purposes. The details specified are in accordance with the principles of design and construction of volumetric glassware given in ISO 384. For piston burettes, see ISO 8655-3.
