Testing Procedures for Seismic Qualification of CANDU Nuclear Power Plants
1. Scope
1.1 This Standard defines the consideration and requirements for performing an acceptable seismic qualification test and presents the different test methods that may be used.
Note: Selected safety related systems are required to be seismically qualified. (See CSA Standard CAN3-N289.1.) Qualification may be by analysis or testing, or a combination thereof, depending on the nature…
Apply only to the type of backflow preventer identified as
dual-check-valve type for use on residential supply service or
individual outlets. They also cover vacuum breakers for use on
laboratory faucets in nominal pipe size of 3/8 only, although
inlet or outlet connections, or both, may be different when so
required for special installations

1. Scope
1.1 This Standard applies to laboratory equipment intended to be connected to supply circuits with nominal system voltages of 750 V and less, for use indoors in nonhazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I.
1.2 This Standard applies to equipment in which protection from electrical shock due to failure of functional insulation is…
Soils - Moisture-Density Relations Standard Proctor Test
The present standard describes the methods of determining the relation between
the moisture content and the density of soils and soil aggregates when these
are compacted in standard moulds using 2,49 kg rammers dropped a height of 305
mm. Four methods are described herein.
NOTE 1 - The laboratory compaction tests described in this standard generally
provide good measures of optimum…
Typical vertical joints between two prefabricated ordinary concrete external wall components — Prope...
For the determination of the watertightness of a joint a method has still not been elaborated. Because of the fundamental importance of this property, solutions are proposed, by way of examples, that experiences and laboratory studies have shown to be satisfactory under the usual conditions. Is applicable to all public or private buildings, used as dwellings, offices, educational or hospital…
The dimensions specified are close to average dimensions of current production in most manufactering countries. The types of beakers are specified: a low-form beaker with spout an a tall-form beaker with spout. The nominal capacities, the material and the construction are described. The basic dimensions are tabulated and the incriptions are defined.
Horizontal joints between load-bearing walls and concrete floors — Laboratory mechanical tests — Eff...
Specifies methods of test for the determination ot the mechanical properties of horizontal joints between load-bearing walls and concrete floors subjected to vertical loading and moments transmitted by the floors. The walls may be interior or exterior walls composed of masonry or of prefabricated units and supporting a floor on one or on both sides.
Grooved vertical joints with connecting bars and concrete infill between large reinforced concrete p...
Specifies a laboratory mechanical method of test for the determination of the relationship between tangential loading and relative displacement for certain types of vertical joints between large reinforced concrete panels subjected to tangential loading. Is applicable to vertical joints between large wall-panels satisfying certain conditions defined in the standard.
