ISO 2861-2:1980 specifies the dimensions of quick-release couplings of the screwed type as used in vacuum technology, as well as those of the “O” rings and the insert which are associated with these tailpieces to ensure coupling tightness. General information is also included which refers to the clamped quick-release coupling standardized internationally in ISO 2861-1, with which the screwed…

These limits are generally appropriate for the products listed. If, however, an International Standard has been issued for an individual product, the method specified there shall be used. Does not apply to articles whose surfaces are composed of mixtures of insulating and conducting areas or articles with substantial surface area of insulating material. A defined system of electrodes is used for…

Specifies the requirements and gives definitions for the raw materials. 23 C is the standard temperature for the test unless otherwise agreed. Stricter requirements may be agreed between the interested parties. Cancels and replaces the ISO Recommendation R 150-1960.

Establishes a list and the standard method of obtaining certain properties. Provides three levels of description to be used. Gives for each of these levels a list of the properties to be specified by the manufacturer in his tender and in his literature.

Basic terms are described, such as distribution systems, hazards during transport, laboratory test of packagesd, performance test schedules. Specification is given for the standardization of test methods and order of tests, selection and modification of test intensities, selection of package attitude, compilation of test schedules and determination of criteria of acceptance. An annex specifies…

1. Scope 1.1 General 1.1.1 This Standard outlines the safety precautions to be observed and procedures to be used before, during, and after demolition operations to provide for the safety of the public, workers, and property. 1.1.2 Demolition procedures for both systematic and rapid progressive failure methods are described. Particular emphasis is given to areas of known concern…

1. Scope 1.1 This Standard applies to stationary, central, forced air unitary heat pumps* rated at 600 V or less, single or polyphase, with or without electric resistance heating, designed to be used in accordance with the Rules of the Canadian Electrical Code, Part I. For purposes of this Standard a heat pump is considered to be an electrically driven device. * Fore convenience, the…

1. Scope 1.1 This Standard applies to add-on heat pumps for comfort heating or heating and cooling not exceeding 20 kW in the cooling mode and rated at 600 V or less, single or polyphase, intended to utilize the fan assemblies and duct work of the existing installed furnaces to form the complete functional systems where the existing parts are not covered by this Standard. Note: For…
