Protective clothing — Protection against liquid chemicals — Determination of resistance of air-imper...
Describes a laboratory test method that enables an assessment to be made of the resistance to permeation by liquids afforded by clothing materials, used for industrial and agricultural applications. The test does not necessarily simulate conditions that may occur in practice.
Limits and methods of measurement of electromagnetic disturbance characteristics of industrial, scie...
Electromagnetic radiation disturbance limits are developed for the purpose of protecting radiocommunication services and signal levels, as well as for taking frequency bands, signal levels, separation distances between the interfering and interfered equipment, desired signal ratio, etc. into account.
High-voltage alternating current switch-fuse combinations
This standard applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches including switch-disconnectors and current-limiting fuses and thus able to interrupt: -any load current up to the rated breaking current of the switch; -any over-current up to the rated short-circuit breaking current of the combination by which automatic…
Defines the detailed classification of family N (insulating liquids) which belong to class L (lubricants, industrial oils and related products) in accordance with ISO 8681 and ISO 6743-0.
Specifies general conditions relating to the sampling for the assessment of quality of oilseeds purchased as industrial raw materials. Nine figures show exemples of suitable apparatus. There is specified the limitationof the size of lot, methods of taking samples, packaging and labelling of samples, the dispatch of samples and the sampling report.
This Standard describes requirements and test methods for materials,
dimensions, workmanship, pipe stiffness, quality control, joining systems, and
marking for SDR 28, 35, and 41 Type PSM PVC sewer pipe and fittings.
Note: Industrial waste disposal lines should be installed only with specific
approval of the regulatory authority, since chemicals not commonly found in
drains and sewers and…
