1. Scope 1.1 This Standard applies to mechanical flue-gas exhausters intended to be installed in a flue pipe, breeching, or chimney and serving appliances burning natural gas, propane, or fuel oil. 1.2 This Standard covers the mechanical and electrical features of mechanical flue-gas exhausters for indoor or outdoor installations. 1.3 This Standard classifies mechanical flue-gas…

Specifies three methods for determination - method A: on a straightened fibre on a graduated rule, under a light tension applied with the aid of forceps and grease; - method B: measurement, using an opisometer, of the length of the image of fibre enlarged by projection on a screen; - method C: by use of a semi-mechanical device. - Intended to replace two existing International Standard, ISO 270…

Defines a procedure for obtaining and for assessing the data necessary to establish long-time stress rupture values for steels for pressure purposes for steels where properties different from those internationally agreed are being claimed. The purpose of a standard procedure is to minimize any differences in long-time estimates obtained in different countries due to differences in the quantity…

1 Scope and field of application This International Standard specifies the 15-pin connector and the assignment of connector pin numbers at the interface between data terminal equipment (DTE) and data circuit terminating equipment (DCE) where CCITT¹) Recommendations X.24, X.26, and X.27 are applicable.

Specifies requirements for spectacle filters and protectors within the spectral region 0,2 to 1000 micron. The work, which was staggered over several years, represents a basic study for which a majority consensus was reached at the international level. To take account of new developments and knowledge relating to lasers a revision of this standard will be undertaken.

1. Scope 1.1 This Standard applies to the mechanical features of new and remanufactured power-operated dispensing devices for petroleum- base liquids for use as fuel in internal combustion engines where such devices are intended primarily to dispense the liquid directly into the fuel storage tank of the engine. 1.2 This Standard does not cover associated nozzles or hose, nor does it…

Includes the dimensions of relays with a rated breaking capacity equal to 2 A or 3 A. Applies to the relays currently used for aircraft electrical power systems. The characteristics of these relays will be defined in a future International Standard.

Is limited to qualitative tests. Table 2 indicates the suitablility of each test for some of the most usual types of metallic coatings. Most of the tests are capable of destroying both the coating and the article being tested. Some destroy the coating only, but it should not be assumed that the articles are undamaged. When particular methods of adhesion testing are included in International…

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…
