This Commentary applies to the design of foundations for fixed offshore structures. The term "foundation" is defined as the seabed, any fill, and any artificial elements (eg, piles or skirts) that penetrate or rest upon these materials and that in whole or in part support production structures and facilities. The Standard is divided into subsections that address (a) site…

1.1 General This Standard addresses the geotechnical engineering aspects of (a) gravity-base structures; (b) fill structures; (c) fill-retention structures; and (d) pile-supported structures. Specific considerations include site investigations, general design principles, the influences of soil and natural processes on the foundation components, and the geotechnical factors that…

Provides guidelines for discharge measurements (especially for site selection) in meandering and braided rivers, and from bridges, following the provisions of ISO 748.

1. Scope 1.1 This Standard specifies requirements for the performance testing of solid-fuel-burning appliances having an air-fuel ratio averaging less than 35:1 as determined by Clause 14. It prescribes a method for determining heat outputs, appliance efficiencies, emission levels and composition, and flue gas flow rates for solid-fuel-fired appliances. The Standard also specifies…

This National Standard of Canada is based on International Standard ISO 3450:1985. This International Standard specifies minimum performances and test criteria for braking systems to enable uniform assessment of the braking capability of earth-moving machinery which operates on work sites or travels on public roads. Service, secondary and parking braking systems and retarders are covered…

1.1 Pertains to nonreinforced circular concrete pipe and fittings intended to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts. Note: This Standard is applicable to manufacture and purchase only. 1.2 This Standard establishes the following three strength classifications of nonreinforced concrete pipe and gives their physical…

1.1 Pertains to reinforced circular concrete pipe and fittings intended to be used for the conveyance of sewage, industrial wastes, and storm water, and for the construction of culverts. Note: This Standard is applicable to manufacture and purchase only. 1.2 This Standard pertains to pipe that is intended to be used for jacking longitudinally in tunnel operations. Note: Such pipe may…

1.1 Pertains to precast reinforced circular concrete manhole sections including base sections, riser sections, catch basins, and appurtenances such as grade rings, tops, and special sections for use in sewer and water works. Note: This Standard is applicable to manufacture and purchase only, not installation. 1.2 The requirements of this Standard are applicable to precast concentric…

1. Scope A257.0 1.1 This Standard describes procedures for testing circular concrete pipe, manhole sections, and joints and includes the following tests: (a) three-edge bearing test (see Clause 3); (b) core strength test (see Clause 4); (c) absorption test (see Clause 5); (d) hydrostatic test (see Clause 6); (e) flat slab top test (see Clause 7);and (f) manhole step test (see…

La présente Norme internationale prescrit trois méthodes pour le mesurage des vitesses de dépôt des composés à base de soufre issus du dioxyde de soufre (SO2) et du sel contenu dans l'air. Elle ne traite pas des mesures de concentration. La concentration de dioxyde de soufre (SO2) et autres polluants dans l'air se mesure suivant d'autres méthodes normalisées, par exemple ISO 4221:…
