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…
Cereals and pulses — Determination of hidden insect infestation — Part 2: Sampling
Shows general principles, apparatus, sampling times and places, pre-sampling inspection and identification of lots, sampling of bilk grain, sampling of grain in bags, preparation of laboratory sample, and packing, labelling and dispatch of laboratory samples.
Equipment for distributing granulated pesticides or herbicides — Test method
Specifies a laboratory test method for granulated pesticide or herbicide distributors, including distributors attached to a basis machine. Annex A tabulates a programm of mandatory tests; annex B describes optional tests; annex C contains an example of a test report, and tabulates test results.
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…
Covers requirements for polyolefin laboratory drainage systems
for corrosive applications. Requirements for materials, pipe,
and fittings are included.
