Canadian General Standards Board
CAN/CGSB-3.2-2019 Heating Fuel Oil DRAFT STAGE 50.00
Supersedes CAN/CSGB-3.2-2017

Scope

This standard applies to three types of middle distillate fuel oils that are suitable for use in liquid-fuel-burning equipment without preheating (Types 0, 1 and 2), and three types of fuel oils that contain residual fuel components and require preheating (Types 4, 5 and 6).
The heating fuel oils covered by this standard are intended for use in oil burning equipment to generate heat for domestic and industrial purposes.

Types 0, 1 and 2 fuel oils are primarily for use in domestic oil burning appliances. They may also be used for some industrial purposes.

a) Type 0 fuel oil is intended for use in fuel domestic oil burning appliances that have outside storage and where ambient temperatures as low as -48°C could be encountered.

b) Type 1 fuel oil is intended primarily for use in sleeve-type and wick-feed burners, excluding space heaters (see 9.1), and in most vaporizing pot-type burner applications. It is also intended for atomizing burners in which Type 2 fuel oil cannot be used satisfactorily. During periods of lower ambient temperature, Type 1 fuel oil may be used in place of Type 2 to minimize waxing problems.

c) Type 2 fuel oil is a heavier distillate than Type 1 and is intended for use in most atomizing-type burner applications. This type of fuel oil is used in most domestic oil burning appliances and in some medium capacity commercial and industrial burners. Type 2 may contain up to 5% biodiesel (See Annex C ).

Types 4, 5 and 6 fuel oils are primarily for use as industrial fuels: suitable for use in the pulp and paper industry, metallurgical operations, heat or power generation, etc.

a) Type 4 is an industrial fuel oil intended primarily for burner installations equipped with limited preheating facilities or with no preheating.

b) Type 5 is a residual fuel oil for burner installations equipped with limited preheating facilities that require a fuel oil of lower viscosity than Type 6.

c) Type 6 is a high-viscosity residual fuel oil for use in burners equipped with preheating facilities to handle such fuels.

Terms and definitions

For the purposes of this National Standard of Canada, the following terms and definitions apply.
3.1
biodiesel
blendstock for middle distillate fuels comprised of mono-alkyl esters of long chain fatty acids derived from renewable sources. In its neat form, biodiesel is commonly designated as B100 or fatty acid alkyl esters with fatty acid methyl esters (FAME) being the most common (see 6.25).

3.x
conventional hydrocarbons
petroleum-derived hydrocarbons from natural gas liquid condensates, crude oil, heavy oil, shale oil and oil sands, which are generally accompanied by lower levels of naturally occurring non-hydrocarbons.

3.2
operability temperature
lowest temperature at which the fuel oil is designed to provide satisfactory performance under the conditions of storage and use (see 6.23, 6.24 and 9.2).The 2.5 percentile low-end design temperature is the temperature at or below which 2.5% of the hourly outside air temperatures are observed to occur for an indicated half month. The 2.5% low-end design temperature for most weather stations in Canada by half month period is available on the Canadian Fuels Association Web site (see 2.2). This data is based upon a statistical analysis of hourly weather readings from weather stations across Canada over the thirty year period from 1981 to 2010 inclusive.

3.3
synthetic hydrocarbons
hydrocarbons derived from non-petroleum sources such as biomass, natural gas, coal, fats and oils by processes such as gasification, reforming, Fischer-Tropsch synthesis, hydroprocessing or hydrocracking (including co-processing with petroleum).

3.y
2.5 percentile low-end design temperature
temperature at or below which 2.5% of the hourly outside air temperatures are observed to occur for an indicated half month. The 2.5% low-end design temperature for most weather stations in Canada by half month period is available on the Canadian Fuels Association Web site (see 2.2). This data is based upon a statistical analysis of hourly weather readings from weather stations across Canada over the thirty year period from 1981 to 2010 inclusive.

CGSB Statement

The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this standard has been developed, is a government agency within Public Services and Procurement Canada. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives.

CGSB has been accredited by the Standards Council of Canada as a national standards-development organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as National Standards of Canada, CGSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy and Procedures Manual for the Development and Maintenance of Standards.

CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. CGSB will initiate the review of this standard within five years of the date of publication. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards.

An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, is found in the CGSB Catalogue at our Web site — www.tpsgc-pwgsc.gc.ca/ongc-cgsb along with more information about CGSB products and services.

Although the intended primary application of this standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose.

The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous.

Standards Council of Canada Statement

The Standards Council of Canada (SCC) is the coordinating body of the Canadian standardization network, which is composed of people and organizations involved in the development, promotion and implementation of standards. Through the collaborative efforts of Canadian standardization network members, standardization is helping to advance the social and economic well-being of Canada and to safeguard the health and safety of Canadians. The network’s efforts are overseen by SCC. The principal objectives of SCC are to foster and promote voluntary standardization as a means of advancing the national economy, supporting sustainable development, benefiting the health, safety and welfare of workers and the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in relation to standardization.

An important facet of the Canadian standards development system is the use of the following principles: consensus; equal access and effective participation by concerned interests; respect for diverse interests and identification of those who should be afforded access to provide the needed balance of interests; mechanism for dispute resolution; openness and transparency; open access by interested parties to the procedures guiding the standards development process; clarity with respect to the processes; and Canadian interest consideration as the initial basis for the development of standards. A National Standard of Canada (NSC) is a standard prepared or reviewed by an SCC-accredited SDO and approved by the SCC according to NSC approval requirements. Approval does not refer to the technical content of the standard, as this remains the responsibility of the SDO. An NSC reflects a consensus of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (including consumers) and others with relevant interests, as may be appropriate to the subject at hand. NSCs are intended to make a significant and timely contribution to the Canadian interest.

Those who have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO that publishes the standard.

The responsibility for approving standards as NSCs rests with:
