1.1 General

This Standard provides criteria for the analysis and design of new buildings and assessment of existing buildings to resist blast loading.

Notes:

The main objective of this Standard is to reduce human casualties and damage to assets due to an air blast.

It should be recognized that the extent and severity of an explosion and resulting damage cannot be predicted with certainty.

The performance of the building and the safety of the occupants are functions of the selected level of protection and the design basis threat (DBT)

Users should ensure they are familiar with applicable legislation. Where this Standard conflicts with applicable legislation, it is assumed that the legislation applies. For additional information on regulatory compliance, see Clause A.1.

1.2 Materials considered

This Standard provides design criteria for concrete, fibre-reinforced polymer (FRP), masonry, steel, and wood. This does not preclude the use of other materials (see Clause 9.1).

Note: FRP design provisions apply to retrofit only.

1.3 Items not addressed

1.3.1

This Standard does not address risk assessment or apply to biological, chemical, cratering, electromagnetic pulse (EMP), ground shock, fragmentation loads, induced fire, penetration, perimeter security, radiation, or thermal effects of explosions.

Note: Although other effects of explosion such as fragmentation loads are important considerations, special design requirements have not been provided in this Standard.

1.3.2

This Standard does not define a design basis threat (DBT). A DBT is building and project specific and it should be specified by the building Oowner and/or the authority having jurisdiction AHJ.

1.4 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.

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.

1.5 Units of measurement

Equations appearing in this Standard are compatible with the following units:

a) area: mm2 (square millimetres);

b) force: N (newtons);

c) length: mm (millimetres);

d) mass: kg;

e) moment: N•mm (newton millimetres); and

f) stress: MPa (megapascals).

1.1 General

This Standard assesses the performance of package wastewater treatment plants that are intended to treat either mixed-wastewater or greywater drainage to produce a treated effluent water quality suitable for non-potable water-reuse applications with a treatment capacity of up to 10 000 L/d (2650 gal/d) or less.

This Standard also covers site-assembled components included in package wastewater treatment plants.

Notes:

1) In this Standard package wastewater treatment plants intended to produce a reuse water quality suitable for authorized non-potable water applications from either mixed-wastewater or greywater drainage are also referred to as package plants.

2) This Standard is not intended to limit the use of multiple package plants to achieve an aggregate treatment capacity greater than 10 000 L/d (2650 gal/d) or as determined by the authority having jurisdiction.

3) This Standard does not cover custom-engineered wastewater treatment systems. For such systems, the authority having jurisdiction should be consulted.

4) Greywater diverters are covered in ASME A112.18.2/CSA B125.2.

5) See Annex F for information on design, warranty, and service policy.

1.2 Test methods

This Standard specifies test methods for evaluating the performance of package plants and minimum requirements with regard to

a) materials;

b) design and construction;

c) operation and treatment performance;

d) markings; and

e) instructions and other documentation.

1.3 Terminology

1.Application

This Standard specifies requirements pertaining to the quality and uniformity of softwood lumber and establishes the designation “Canadian Standard Lumber” for lumber that meets the requirements of this Standard (see Clause 4). 

This Standard covers the following topics:

a) accreditation board and agency responsibilities (Clause 5);

b) measurement (Clause 6)

c) standard sizes (Clause 7);

d) grading rule requirements (Clause 8);

f) identification (grade stamps and certificates) (Clause 9); and

g) determination of design properties (Clause 10).

This Standard applies to lumber produced and consumed in and exported from Canada, and for lumber imported into Canada.

This Standard provides for the grading of structural lumber by both visual and mechanical means.

This Standard also includes detailed Annexes covering lumber terminology and lumber industry abbreviations.

This Standard does not cover trade practices, grades (other than grading rules and identification), the details of accreditation board and grading agency inspection procedures, or strength and related properties.

The provisions of this Standard apply to species when the species is included in rules approved by the accreditation board.  Although this Standard applies to softwood lumber, it may be applied to hardwood lumber used in applications that ordinarily use softwood lumber.

2.Terminology

In CSA Standards,

a) “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;

b) “should” is used to express a recommendation or that which is advised but not required;

c) “may” is used to express an option or that which is permissible within the limits of the standard; and

d) “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.

3.Units

In keeping with the practice of lumber manufacturers throughout North America, sizes in this Standard are given in board measure units, which are expressed in yard/pound units (see Section 6.1). Equivalent SI (metric) sizes, rounded to the nearest millimeter, are given in parentheses for the sake of convenience in use and in commercial transactions.  The values given in yard/pound units are the standard. The values given in parentheses are for information only.  See Annex E for a discussion of how metric dimensions have been calculated for this Standard.
