1 Scope

1.1

This test method determines the wind uplift resistance of membrane-roofing assemblies when subjected to dynamic wind load cycles. The test methods are applicable to

a) mechanically attached membrane roofing systems (MARS);

b) adhesive applied roofing systems (AARS); and

c) partially attached (hybrid) membrane roofing systems (PARS).

The roofing assembly consists of a deck and roofing system. The roofing system include membrane and components such as vapour barriers or retarders, insulation, cover board, etc. It is subjected to a dynamic load sequence that has been developed based on wind pressure records, simulating the effects of wind on a membrane-roof assembly.

Note: The roof membrane may be designated as the plane of air tightness.

1.2

The following limitations apply for the test methods in this Standard:

a)  Testing in accordance with this test method is limited to the MARS having a fastener row separation not greater than 2896 mm (114 in) and fastener in-line spacing not greater than 610 mm (24 in).

b)  Testing in accordance with this test method is limited to the PARS and AARS when adhesive spacing is not greater than 610 mm (24 in).

1.1 General

This Standard specifies safety requirements for users of industrial robot cells, over the entire lifecycle of the machinery.

This Standard is supplementary to and used in conjunction with the requirements for industrial robots covered by Part 1 of CSA Z434 and requirements for the integration of industrial robot systems, applications, and cells covered by Part 2 of CSA Z434.

Note: The user is responsible for the continued safe operation of robot applications and reduction of risk as stated in Part 2 of CSA Z434. Among other risk reduction measures described in this document, training or retraining of affected persons is an important part of risk reduction.

1.2 Exclusions

When a manipulator is mounted to a mobile platform, rather than permanently mounted in a single location, it is an industrial mobile robot and is not covered by this Standard. See ANSI/A3 R15.08 for the safety requirements for an industrial mobile robot (IMR).

1.1

This Standard describes general requirements, apparatus, and test methods to be used in carrying out applicable tests and calculations for rigid nonmetallic conduits, elbows, bends, and associated fittings required by the rigid nonmetallic conduit Standards of the Canadian Electrical Code, Part II.

1.2

The various types of rigid nonmetallic conduits are as follows:

a)    rigid PVC conduit for direct burial and for masonry and concrete encasement, as specified in CSA C22.2 No. 211.1; and

b)    rigid PVC (unplasticized) conduit, as specified in CSA C22.2 No. 211.2.

1.1 

This Standard describes the investigations required to obtain the seismological and geological information necessary to determine the seismic ground motion that will be used in seismic qualification of safety-related nuclear power plant structures, systems, and components (SSCs), and the potential for secondary earthquake effects (e.g., tsunami, seiche, volcanism, slope instability, surface faults, surface instability, and dam failures) that can have a direct or indirect effect on plant safety or operation.

Notes:

1)This Standard establishes the basis for a family of seismic hazard results that can be used as input to CSA N289Series of Standards. This Standard does not specify

a)ground motion parameters to be used in design;

b)probability level; or

c)degree of confidence to be achieved.

2)The investigations specified in this Standard should be updated periodically to reflect gained knowledge and modern requirements. The investigations may be conducted independently or as part of the periodic safety review (refer to REGDOC-2.3.3, CSA N289.1, and CSA N290.18).

1.2 

This Standard was developed for the determination of ground motions for Eastern North American regions of low to moderate seismic hazard, comparable to the levels near Canada’s existing nuclear power plants. In regions of higher seismic hazard, the assessment of strong earthquake shaking can be more complex due to near-fault and other effects that are beyond the scope of this Standard. Therefore, while the provisions of this Standard can be applied to any nuclear power plant site, additional provisions might be required for high seismic hazard sites.

Note: Guidance regarding additional provisions for high seismic hazard sites may be obtained from IAEA Specific Safety Guide SSG-9, and relevant codes of other countries.

1.3 

This Standard may be applied, as appropriate, to other nuclear facilities under the jurisdiction of the Government of Canada’s Nuclear Safety and Control Act.

1.4 

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

1.1

Cette norme décrit les études exigées pour obtenir les informations sismologiques et géologiques nécessaires en vue de déterminer les mouvements sismiques du sol qui seront utilisés lors de la qualification sismique des structures, systèmes et composants (SSC) de centrales nucléaires liés à la sûreté, et le risque d’effets secondaires du séisme (p. ex., tsunami, seiche, activité volcanique, instabilité de pente, défauts de surface, instabilité de surface et défaillances de barrage) susceptibles d’avoir un effet direct ou indirect sur la sécurité ou l’exploitation de la centrale.

Notes :

1) Cette norme présente un ensemble de résultats associés aux aléas sismiques qui sont susceptibles d’être utilisés pour la série de normes CSA N289. Cette norme ne prescrit pas ce qui suit :

a) les paramètres de mouvement du sol à utiliser pour la conception;

b) le niveau de probabilité; ou

c) le degré de confiance nécessaire.

2) Les études spécifiées dans cette norme devraient être mises à jour périodiquement pour tenir compte des connaissances acquises et des exigences modernes. Les études peuvent être menées indépendamment ou dans le cadre de la revue de sûreté périodique (voir REGDOC-2.3.3, CSA N289.1 et CSA N290.18).

1.2

Cette norme a été élaborée en vue de permettre la détermination des mouvements du sol pour des régions de l’est de l’Amérique du Nord où les aléas sismiques sont faibles à moyens, comparables aux niveaux qui existent près des centrales nucléaires existantes du Canada. Dans les régions qui présentent un plus grand aléa sismique, l’évaluation des fortes secousses sismiques risque d’être plus compliquée en raison des quasi-failles et autres effets qui dépassent le cadre de cette norme. Donc, bien que les dispositions de cette norme sont susceptibles de s’appliquer à tout site de centrale nucléaire, des exigences supplémentaires pourraient être requises pour les sites à plus grand aléa sismique.

Note : Des lignes directrices additionnelles visant les sites à haut aléa sismique peuvent être obtenues dans le Specific Safety Guide SSG-9 de l’IAEA, et dans les codes pertinents d’autres pays.

1.3

Cette norme peut s’appliquer, s’il y a lieu, à d’autres installations nucléaires visées par la Loi sur la sûreté et la réglementation nucléaires du gouvernement du Canada.

1.4

Dans cette norme, le terme « doit » indique une exigence, c.-à-d., une prescription que l’utilisateur est obligé de respecter pour assurer la conformité à la norme; « devrait » indique une recommandation ou ce qu’il est conseillé mais non obligatoire de faire; et « peut » indique une possibilité ou ce qu’il est permis de faire dans les limites de la norme.

Les notes qui accompagnent les articles ne comprennent pas de prescriptions ni de recommandations. Elles servent à séparer du texte les explications ou les renseignements de nature informative qui ne font pas proprement partie de la norme.

Les notes au bas des figures et des tableaux font partie de ceux-ci et peuvent être rédigées comme des prescriptions.

Les annexes sont qualifiées de normatives (obligatoires) ou d’informatives (facultatives) pour en préciser l’application.
