1  Scope and application

1.1  General

This Standard provides rules and requirements for the design, fabrication, and erection of steel structures. The design is based on limit states. The term “steel structures” refers to structural members and frames that consist primarily of structural steel components, including the detail parts, welds, bolts, or other fasteners required in fabrication and erection. This Standard also applies to structural steel components in structures framed in other materials. The clauses related to fabrication and erection, serve to show that design is inextricably a part of the design-fabrication-erection sequence and cannot be considered in isolation. For matters concerning standard practice pertinent to the fabrication and erection of structural steel not covered in this Standard, see Annex A.

1.2  Requirements

Requirements for steel structures such as bridges, antenna towers, offshore structures, and cold-formed steel structural members are given in other CSA Standards.

1.3  Application

This Standard applies unconditionally to steel structures, except that supplementary rules or requirements may be necessary for

(a)    unusual types of construction;

(b)   mixed systems of construction;

(c)    steel structures that

(i)     have great height or spans;

(ii)    are required to be movable or be readily dismantled;

(iii)   are exposed to severe environmental conditions;

(iv)   are exposed to severe loads such as those resulting from vehicle impact or explosion;

(v)    are required to satisfy aesthetic, architectural, or other requirements of a non-structural nature;

(vi)   employ materials or products not listed in Clause 5; or

(vii)  have other special features that could affect the design, fabrication, or erection;

(d)   tanks, stacks, other platework structures, poles, and piling; and

(e)    crane-supporting structures.

1.4  Other standards

The use of other standards for the design, fabrication, erection, and/or inspection of members or parts of steel structures is neither warranted nor acceptable except where specifically directed in this Standard. The design formulas provided in this Standard may be supplemented by a rational design based on theory, analysis, and engineering practice acceptable to the regulatory authority, provided that nominal margins (or factors) of safety are at least equal to those intended in the provisions of this Standard are maintained. The substitution of other standards or criteria for fabrication, erection and/or inspection is expressly prohibited unless specifically directed in this Standard.

1.5  Terminology

In CSA Standards, “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; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. 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. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

Adoption with deviations of Standard ISO 4427.

This is the first edition of CSA Standard CSA B137.17, Plastics piping systems – Polyethylene (PE) pipe and fittings for water supply, which is an adoption with Canadian deviations, of the identically titled ISO (International Organization for Standardization), Standard 4427 (first edition, 2007), including Technical Corrigendum 1:2008. Both the Standard and the Technical Corrigendum are currently available from ISO in English only.

(ii)    prefabricated masonry panels; and

(b)   fasteners used to attach equipment or fixtures to buildings.

1.3  

This Standard recognizes two types of masonry connectors:

(a)    connectors, including repair connectors, designed in accordance with the performance requirements of this Standard; and

(b)   prescriptive connectors, which offer a simple prescriptive solution (or deemed-to-comply solution) to the performance requirements of this Standard.

1.4  

In CSA Standards, “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. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Legends to equations and figures are considered requirements.

1 Scope

1.1

The Standard applies to water temperature limiting devices (herein referred to as the “device”) that limit the hot or tempered water temperature to fittings for fixtures such as sinks, lavatories, or bathtubs and that are intended to reduce the risk of scalding.

1.2

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

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.3

SI units are the units of record in Canada. In this Standard, the inch/pound units are shown in parentheses.

The values stated in each measurement system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems can result in non-conformance with this Standard.

All references to gallons are to U.S. gallons.

For information on the conversion criteria used in this Standard, see Annex A.

1  Scope

1.1  General

This Standard specifies requirements for

(a)     mortar for use in bedding, jointing, and bonding of masonry units; and

(b)     grout for use in filling core, cell, or cavity space

in unit masonry construction.

Notes:

(1)     The term “unit masonry” refers to masonry construction using clay (shale), calcium silicate (sand-lime), or concrete masonry units, with individual units not more than 200 mm high and 400 mm long, and not less than 75 mm thick. For other masonry units, the proportions of ingredients and any additives to be used in the mortar for masonry construction should be based on laboratory or field experience with the mortar ingredients and the particular masonry units to be used.

(2)     It is not the intent of this Standard to imply that all unit masonry constructed with mortar containing only conventional ingredients mixed conventionally will satisfy the design strengths in CSA S304.1 or the minimum bond requirements of Clause 9.1.1 of this Standard. When mortar bond is a concern, and the mortar considered for use satisfies the requirements of this Standard, the manufacturer of the unit should be contacted to provide independent laboratory data or to certify adequate bond with the mortar. Alternatively, when reasonable assurances of performance cannot be so obtained, mortar bond tests may be carried out under expected field conditions, before commencement of work, in accordance with the requirements of the ASTM C 1072 “Standard Test Methods for Measurement of Masonry Flexural Bond Strength” or CSA S304.

1.2  Classification

This standard specifies requirements for:

(a)     two types of mortar, Type N and Type S;

(b)     two types of grout, fine and coarse.

Note: Annex A and D provide guidance on selecting and specifying other types of mortar, which are often used for restoring older, traditional masonry but are not recognized by CSA S304 for modern engineered masonry.

1.3  Terminology

In CSA Standards, “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.
