ISO 140-16:2006, as a complement to ISO 140-3, specifies the laboratory measurement of the improvement of the sound-reduction index of a wall or ceiling when covered by an additional acoustical lining. It also provides for individual non-standardized basic elements. ISO 140-16:2006 does not deal with the sound-reduction improvement by linings on flexible lightweight structures, such as timber-…

Filters are graded according to their pore size index in one of the eight classes specified. This is applicable to laboratory filters made of glass, vitreous silica, ceramics, metals and plastic materials. Annex A specifies a method for determination of pore size index. Annex B and C concern with a procedure for assessing uniformity of filters and for determination of air permeability.

ISO 5270:2012 specifies the relevant International Standards to be used for the determination of physical properties of laboratory sheets made of all kind of pulps. It is applicable to laboratory sheets prepared in accordance with ISO 5269-1, ISO 5269-2 or ISO 5269-3. In ISO 5270:2012, it is left to the pulp producer and the pulp user to agree upon which properties are relevant to be tested. The…

ISO 17892-6:2017 specifies a method of undrained strength index testing of both undisturbed and remoulded specimens of fine grained soils by the fall cone method. ISO 17892-6:2017 is applicable to the laboratory estimation of undrained shear strength of a soil test specimen within the scope of geotechnical investigations. In the fall cone test, a cone is allowed to fall with its tip towards a…

Spectrometric method for the determination of anionic surfactants by measurement of the methylene blue index (MBAS) in aqueous media. Suitable for drinking water, surface water and waste water. Does apply for laboratory scale and technical large-scale waste-water treatment plants.

The scope of ISO 18417:2017 covers - iodine sorbents for nuclear power plants, nuclear facilities, research and other nuclear reactors, - iodine sorbents for laboratories, including nuclear medicine, and - iodine sorbents for sampling equipment on sample lines. ISO 18417:2017 applies to iodine sorbents manufacturers and operators in order to measure the actual performance of these…

ISO 10848-4:2010 specifies laboratory measurements of normalized flanking level difference, normalized flanking impact sound pressure level or vibration reduction index of buildings where at least one of the elements that form the construction under test is not a light element. ISO 10848-4:2010 applies to T- or X-junctions.

This proposal relates to a method for testing the low-temperature cracking index test of thermosetting resin based material for power electronic equipment.The corresponding molds, stress module and sample preparation are also described. The test method described in this proposal is suitable for quantifying and comparing the low-temperature cracking of thermosetting resin based material in…

Determines the testing methods that shall be used to determine minimum and maximum densities of cohesionless soils in the laboratory by pouring the loose material and by densification of the material using vibration respectively. These two densities are used to calculate the relative density index.

This standard specifies laboratory test methods that shall be used to determine minimum and maximum densities of cohesionless soils first by pouring the loose material and then by densification of the material using vibration. These two densities are used to calculate the relative density index.
