Full Description

Preface:

This is the fifth edition of CSA O302.1, Scaling roundwood, which supersedes the previous editions, published in 2009, 2000, 1986, and 1977, and the fourth edition of CSA O302.2, Measurement of wood chips, tree residues, and by-products, which supersedes the previous editions, published in 2009, 2000, and 1986 under the title Measurement of Woodchips, Tree Residues, and Byproducts.

CSA O302.1 sets out criteria for scaling roundwood. It is intended as a source document on log scaling for producers and purchasers of primary wood products in Canada. It is also intended to provide a commonly accepted basis for scaling procedures established by the provinces and territories for determining the measure of timber cut and subject to timber fees.

CSA O302.2 sets out sampling procedures and reliability criteria for the measurement of the wood content and quality of wood chips produced as a primary product at a mill or landing site or as a by-product or residue of a sawmilling or other conversion operation. It addresses the determination of chip quality and wood content of chips, considering both individual chips and large-volume chip piles, e.g., barges of wood chips.

The changes to this edition include the following:
(a) In CSA O302.1: the addition of Clause 13, which provides the minimum criteria for using timber dimensional measuring devices to measure the diameter and length of individual roundwood, in order to determine gross volumes.
(b) In CSA O302.2: no changes were made.

O302.1-15 - Scaling roundwood

Scope:

1.1
This Standard specifies minimum requirements for scaling roundwood and covers processes for quality and quantification assurance.

Note: Requirements on measuring and estimating quantities of wood chips, tree residues, and by-products are specified in CSA O302.2.

1.2
This Standard is intended for individuals or agencies charged with scaling and check scaling of primary forest products in Canada.

1.3
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. 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.
