1.1 General

This Standard provides a clear framework for issuers to accelerate and de-risk biomanufacturing project development in specific geographic regions. It guides issuers in conducting technical and geographic evaluations of BDO zones, comprehensively assessing supply chain and infrastructure risks to achieve this goal.

This Document is organized into two risk categories (supply chain risk and infrastructure risk) that are foundational to two key project developer questions:

What is the supply chain risk?

What is the infrastructure risk for a new entrant locating in a particular region?

Each risk category identifies specific risk factors (i.e., the itemized risk elements within each category) and risk indicators (i.e., the markers of risk for each factor), and establishes guidance to point issuers to the best available methods and tools available to measure and mitigate risks (see Figure 1).

1.2 Guidance for use of CSA W209

This Standard is intended to provide a framework and guidance document for the use of CSA W209 to assess the regional readiness of geographical areas for biomanufacturing. CSA W209 enables more accurate quantification of biomass supply chain risk for biomanufacturing projects, while this Standard enables more accurate quantification of supply chain and infrastructure risk for geographic regions.

CSA W209 serves as a due diligence tool to support the financing of biomanufacturing projects. This Standard complements this by acting as an economic development tool that enhances decision-making for site locations, benefiting project developers and governments by enabling faster and more informed choices.

By achieving these objectives, this Standard enables the creation of a comprehensive network of rated BDO zones, facilitating informed decision-making for biobased developers and investors, and catalyzing the growth of the bioeconomy.

2) In Mexico, this construction is not allowed.

3) In the United States:

i) 12 AWG (3.3 mm2) and 10 AWG (5.3 mm2) solid; and

ii) 12 AWG (3.3 mm2) to 2 000 kcmil (1 010 mm2) stranded, Class B concentric, compressed, and Class C concentric.

c) Copper:

1) 30 AWG (0.05 mm2) to 10 AWG (5.3 mm2) solid; and

2) 30 AWG (0.05 mm2) to 16 AWG (1.3 mm2) stranded, Class K; and.

e) Rigid (solid and stranded) metric wire sizes, Classes 1, 2, 5, and 6, in the range of 0.5 – 1 000 mm2, in addition to AWG/kcmil sizes, with AWG/kcmil ratings mandatory and metric wire ratings optional.

NOTE 1: Metric wire sizes are based on the IEC Standard for Conductors of Insulated Cables, IEC 60228.

NOTE 2: For example, a connector rated for 6 AWG – 350 kcmil may be additionally rated for 16 –150 mm2. See Annex B for example

f) Other class and strand configurations as indicated by marking.
 

1.4 This Standard is intended for connectors suitable for currents not exceeding the ampacity of insulated conductors rated 75 °C or 90 °C in accordance with the rating of the connector, if provided.

1.5  These requirements cover insulated connectors, insulating caps, and covers intended for use at 2 000 volts or less and uninsulated connectors for use in general use circuits rated 35 000 volts nominal or less. Insulated connectors and connectors with insulating caps or covers are intended for indoor use or installed in enclosures rated for the environment where the interior of the enclosure is a dry location.

In Canada, uninsulated connectors may also be used in applications up to 5 000 volts phase-to-phase where allowed and installed in accordance with Section 36 of the Canadian Electrical Code, Part I, CSA C22.1. For products intended for use in Canada, general requirements are given in CSA C22.2 No. 0.

1.6  This Standard does not apply to:

a) Insulated connectors for voltage levels above 2 000 V;

b) Manual twist-on connectors;

c) Built-in terminal connectors in devices rated less than 30 A intended for outlet box mounting or having provision for stress relief;

d) Flat quick connect terminals;

e) Wire binding screw terminals; 

f) Bare or covered ferrules and

g) Mated connectors, including latching or locking type PV connectors.

CSA Scope

[Add the following paragraphs]

The requirements of the IEC 60079 series of Standards cover protection with respect to explosion hazard only. The CSA C22.2 No. 60079 series of Standards (based on the adoption of the corresponding IEC Standards) is to be used in conjunction with other applicable Standards containing the appropriate electrical safety requirements for general use equipment.

This Standard applies to the safety of such equipment designed and constructed for installation and use in accordance with CSA C22.1, Canadian Electrical Code, Part I.

IEC Scope

This part of IEC 60079 specifies general and testing requirements for electrical resistance trace heaters for application in explosive atmospheres with the exclusion of those for Equipment Protection Levels (EPL) Ga, Da, Ma and Mb equipment. This document covers trace heaters that comprise either factory or field (worksite) assembled units, and which can be series trace heaters, parallel trace heaters, trace heater pads, or trace heater panels that have been assembled and/or terminated in accordance with the manufacturer's instructions.

This document also includes requirements for termination assemblies and control methods used with trace heating systems. The explosive atmospheres referred to in this document are those defined in IEC 60079-10-1 and IEC 60079-10-2. Annex F and Annex G outline the application of this document for those users applying the Division method of area classification.
