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.
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 "…
Rubber, vulcanized — Determination of adhesion to wire cord
Two methods are given which are applicable primarily to test pieces prepared in the laboratory under standard conditions, such as may be used for the development and control of materials and processes used in the manufacture of products reinforced with wire cord. Test pieces of cord and rubber are prepared together by vulcanizing them under pressure. In method 1 the exterior surface of the rubber…
