Pyrometric reference cones for laboratory use — Specification
Specifies the characteristics of a standard series of pyrometric reference cones, which are used for determining the pyrometric cone equivalent (refractoriness) of refractory materials, over the temperature range 1500 to 1800 C. The cones specified in this International Standard are suitable for use in the procedure described in ISO 528, excluding determinations at 1500 and 1800 C.
Rubber compounding ingredients — Carbon black — Determination of individual pellet crushing strength
Defines the method as an interim method because the reproducibility between various laboratories is still too different. The crushing strength of individual pellets can affect the dispersion of carbon black in polymers, on bulk handling, and on conveying properties.
Soils - Determination of Minimum and Maximum Densities of Cohesionless Soils -
Vibrating Table Test
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.
Defines performance criteria for an optical data channel used in impact tests on road vehicles, when numerical time and space data are taken from the images to analyse impact test results. The requirements are to facilitate comparison between results obtained by different laboratories.
Applies to asbestos-cement pipe and couplings, intended primarily
for use in exhaust conveying fumes from laboratory hoods, from
certain processes, and in ventilation systems conveying treated
air.
Water for analytical laboratory use — Specification and test methods
Specifies the requirements for three grades for the analysis of inorganic chemicals. Not applicable to organic trace analysis, analysis of surface-active agents and biological or medical analysis. The material shall be a clear, colourless liquid as assessed by inspection. Classifies according to the content: free from dissolved or colloidal ionic and organic contaminants, very low inorganic,…
Textiles — Fibres and yarns — Determination of commercial mass of consignments — Part 2: Methods for...
Laboratory samples are taken from the containers in the consignment samples obtained as specified in ISO 6741-1 and placed in stoppered, air-tight vessels for subsequent processing. Sampling procedures for different forms of fibres and yarns are described.
Biological Containment Cabinets: Installation and Field Testing
Applies to the installation and testing of Class I and Ii
biological containment cabinets. Such cabinets are designed to
control and eliminate particulates and aerosols generated by
routine laboratory manipulations.
Applies to new voltage transformers for use with electrical
measuring instruments and electrical protective devices at
frequencies from 15 Hz to 100 Hz.
The general requirements apply to all voltage transformers, but,
for certain types, e.g. capacitor voltage transformers, the
requirements are subject to the modifications stated in the
appropriate chapter. Although the requirements relate…
