Textile Test Methods Quantitative Analysis of Fibre Mixtures -
Introduction
Laboratory methods for the quantitative analysis of mixtures of
textile fibres may be classified broadly as physical or chemical.
The most frequently employed physical method is mechanical
separation. This method is appli[Ccable only when each component
fibre in the fabric is confined to a different yarn. In such
cases, the composition can be determined simply by separating the
yarns and…
Standard Method of Test for Surface Burning Characteristics of Flooring,
Floor Covering, and Misce...
1. SCOPE
1.1 This method is applicable to the finished surface or covering of a floor
extending to a maximum depth of 65 mm. It may also be applied to materials
that cannot conveniently be tested in a ceiling mounted configuration.
Thermoplastic and loose fill materials might be included in this category.
1.2 The primary purpose of the test is to determine the comparative burning…
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,…
