Measurement of radioactivity in the environment — Soil — Part 5: Measurement of strontium 90
ISO 18589-5:2009 describes the principles for the measurement of the activity of 90Sr in equilibrium with 90Y and 89Sr, pure beta-emitting radionuclides, in soil samples. Different chemical separation methods are presented to produce strontium and yttrium sources, the activity of which is determined using proportional counter (PC) or liquid scintillation counter (LSC). The selection of the…

Specification for radio disturbance and immunity measuring apparatus and methods - Part 4-1: Uncerta...
CISPR/TR 16-4-1:2009 gives guidance on the treatment of uncertainties to those who are involved in the development or modification of CISPR electromagnetic compatibility (EMC) standards. In addition, this part provides useful background information for those who apply the standards and the uncertainty aspects in practice. The objectives of this part are to:
a) identify the parameters or sources…
Electroacoustics - Measurement microphones - Part 2: Primary method for pressure calibration of labo...
IEC 61094-2:2009 is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of condenser microphone having the same mechanical dimensions and specifies a primary method of determining the complex pressure sensitivity so as to establish a reproducible and accurate basis for the measurement of sound pressure. This second edition cancels and replaces the…
Earth-moving machinery — Operator enclosure environment — Part 6: Determination of effect of solar h...
ISO 10263-6:2009 specifies a test method for simulating solar heating in the laboratory and measuring the radiant heat energy from a natural or simulated source. It is applicable to earth-moving machines when equipped with an operator enclosure
Road vehicles — Air filters for passenger compartments — Part 2: Test for gaseous filtration
ISO 11155-2:2009 specifies a test comprising several methods for measuring the dynamic gas adsorption of air filters in the passenger compartments of road vehicles. These laboratory test methods are applicable to air filters that improve air quality by reducing concentrations of gaseous, odorous or hazardous components from ambient or re-circulated air, or both, in the vehicle cabin. They provide…
Electromagnetic compatibility (EMC) - Part 4-2: Testing and measurement techniques - Electrostatic d...
IEC 61000-4-2:2008 relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and from personnel to adjacent objects. It additionally defines ranges of test levels which relate to different environmental and installation conditions and establishes test procedures. The object of IEC 61000-4-2:…
Flexible cellular polymeric materials — Determination of hardness (indentation technique)
The indentation hardness of flexible cellular materials is a measure of their load-bearing properties. ISO 2439:2008 specifies four methods (A to D) for the determination of indentation hardness and one method (E) for determination of compressive deflection coefficient and hysteresis loss rate of flexible cellular materials. Annex A provides a summary of test parameters and typical force-…
Paper and board — Determination of colour by diffuse reflectance — Part 3: Indoor illumination condi...
ISO 5631-3:2008 specifies a method for measuring the colour of paper and board by the diffuse reflectance method with the elimination of specular gloss.
ISO 5631-3:2008 is primarily intended for measuring the colour of paper and board to be used in the graphic arts industry where that industry specifies the measurement of colour under D50/2° conditions in accordance with ISO 13655.
The method…
