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.
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,…
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…
Light olefins for industrial use — Determination of molecular oxygen in gaseous phase — Electrochemi...
After sampling and preparation of the laboratory sample the gaseous test portion is passed at a given rate through an electrochemical cell previously calibrated with air or with standard mixtures containing a known amount of oxygen, and the concentration of oxygen in the gaseous olefin is measured. The method is applicable to light olefins having an oxygen content greater than 1 milliliter per…
Radio interference characteristics of overhead power lines and high-voltage equipment. Part 2: Metho...
The methods of measurement detail the techniques and procedures for
use when measuring fields on site near to an overhead line and also
the techniques and procedures for making laboratory measurements of
interference voltages and currents generated by line equipment and
accessories.
The procedures for determining limits define the expected values of
radio noise field and the width of the "…
Industrial-process control valves. Part 8: Noise considerations. Section One: Laboratory measurement...
Defines equipment, methods and procedures for obtaining laboratory measurements of airborne sound-pressure levels radiated by control valves and/or associated piping configurations, including fixed restrictions, through which compressible fluids are passing. Provides a method of testing the noise-generating characteristics of control valves. The noise characteristics to be determined are useful…
Soils - Moisture-Density Relations Modified Proctor Test
The present standard describes the method to determine the relation between the
moisture content and the density of soils and soil aggregates when these are
compacted in standard moulds using 4,54 kg rammers dropped a height of 457 mm.
Four methods are described herein.
NOTE 1 - The laboratory compaction tests described in this standard generally
provide good measures of optimum moisture…
