Preface<\/strong><\/p>\n

<\/p>\n

This is the second edition of the CSA B481 Series of Standards, Grease interceptors. It supersedes the previous edition published in 2007. It consists of the following Standards:<\/p>\n

<\/p>\n

(a) CSA B481.0, Material, design, and construction requirements for grease interceptors;<\/p>\n

<\/p>\n

(b) CSA B481.1, Testing and rating of grease interceptors using lard;<\/p>\n

<\/p>\n

(c) CSA B481.2, Testing and rating of grease interceptors using oil;<\/p>\n

<\/p>\n

(d) CSA B481.3, Sizing, selection, location, and installation of grease interceptors;<\/p>\n

<\/p>\n

(e) CSA B481.4, Maintenance of grease interceptors; and<\/p>\n

<\/p>\n

(f) CSA B481.5, Testing and rating of grease interceptors equipped with a grease removal device.<\/p>\n

<\/p>\n

Differences from the previous edition of the CSA B481 Series include<\/p>\n

<\/p>\n

(a) changes to the requirements in CSA B481.0;<\/p>\n

<\/p>\n

(b) changes to the requirements in CSA B481.3; and<\/p>\n

<\/p>\n

(c) the addition of CSA B481.5 to the Series.<\/p>\n

<\/p>\n

These Standards are considered suitable for use for conformity assessment within the stated scope of each Standard.<\/p>\n

B481.0-12 – Material, design, and construction requirements for grease interceptors<\/strong><\/p>\n

<\/p>\n

B481 SERIES-12 – Grease interceptors<\/strong><\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1<\/p>\n

This Standard specifies material, design, and construction requirements for manufactured grease interceptors intended to separate and collect organic fats, oils, and greases from water.<\/p>\n

<\/p>\n

1.2<\/p>\n

Grease interceptors covered in the CSA B481 Series<\/p>\n

<\/p>\n

a) are installed in drainage systems to reduce the amount of organic fats, oils, and greases entering the sanitary system;<\/p>\n

<\/p>\n

b) may be for indoor applications (usually referred to as the under-the-counter type) or for outdoor applications (i.e., underground);<\/p>\n

<\/p>\n

c) have a flow rating of not less than 26 L\/min (7 gpm) and not more than 380 L\/min (100 gpm); and<\/p>\n

<\/p>\n

Note: Grease interceptors can operate at any flow rate below their flow rating.<\/p>\n

<\/p>\n

d) are hydromechanical batch-flow interceptors.<\/p>\n

<\/p>\n

1.3<\/p>\n

The CSA B481 Series does not cover interceptors intended for rainwater, sanitary wastewater, or wastewater containing petroleum products such as gasoline, heating oils, or mineral oils.<\/p>\n

<\/p>\n

1.4<\/p>\n

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.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n

<\/p>\n

1.5<\/p>\n

In the CSA B481 Series, the values given in SI (metric) units are the standard. Where values are given in parentheses, they are for information only.<\/p>\n

<\/p>\n

Litres (metric liquid) per minute is abbreviated L\/min and gallons (US liquid) per minute is abbreviated gpm. All references to gallons are to US liquid gallons.<\/p>\n
