Preface
This is the second edition of CSA Z107.58, Noise emission declarations for machinery. It supersedes the previous edition, published in 2002. This Standard provides information on noise emission, which should be supplied with new machinery, to manufacturers, purchasers, and importers/exporters.
A major goal of this Standard is to help manufacturers efficiently provide standardized information on noise emissions from machinery and equipment (i.e., noise emission declarations). This Standard enables manufacturers to
a) meet the European Commission requirements specified in reference documents listed in Clause 2 (EC 00, EC 06, EC 10, EC 13) for marketing certain types of machinery (see Annex E) in the European Economic Area (i.e., the European Union, Iceland, Norway, and Liechtenstein); and
b) meet purchase specifications of customers in Canada and the USA.
This Standard also promotes the manufacturing of quieter machinery as a competitive advantage.
Another objective of this Standard is to help workplace managers (purchasers) use noise emission declarations to purchase quieter machinery and plan noise control strategies. It does so by enabling manufacturers to formally provide sound-level data in an agreed format. This benefits workplace managers by enabling them to comply cost-effectively with Canadian occupational and environmental noise regulations.
It is expected that achieving these objectives will result in quieter workplaces. The benefits to workers, workplace managers, and communities in the vicinity of the workplace include
- reduced risk to workers of noise-induced hearing loss;
- a decrease in the number of disability claims for occupational hearing loss, which is currently the cause of thousands of disability claims per year in Canada (see HC 10);
- enhanced capability for workers to communicate and to hear warning sounds, which improves productivity and safety;
- reduced noise annoyance for communities in the vicinity of the workplace; and
- extension of workplace operating hours into the evening or throughout the night.
Scope
1.1
This Standard is intended for manufacturers and purchasers of machinery that is sold in, imported to, or exported from Canada. It is also intended for regulators, acoustical professionals, and other interested parties.
1.2
This Standard is intended to provide
a) guidance on the steps required to provide and verify noise emission declarations for machinery and equipment intended for the workplace;
b) guidance in the use of noise emission declarations to purchase quieter machinery and plan noise control;
c) requirements consistent with the European Union directives pertaining to machinery (EC 00, EC 06, EC 10, EC 13) and the supporting international and European standards, prepared by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN);
d) information that could also be applicable to the use of similar US national standards of the American National Standards Institute (ANSI); and
e) additional requirements reflecting Canadian concerns with respect to noise measurements, employee exposure, and engineering noise control.
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 (nonmandatory) to define their application.
