New CSA Standard for Machinery Electrical Equipment

Electrical Equipment of Machinery

Machinery electrical equipment
Industrial electrical control panels

Most modern machinery is controlled electrically, or electronically. There are a number of standards that apply to the design of control systems for machinery, with IEC 60204-1 and it’s EN equivalent, along with IEC 61439-1 and IEC 61439-2 as the predominant standards internationally, and NFPA 79 as the predominant standard in the US and Canada. Until now.

CSA C22.2 No. 301, Industrial Electrical Machinery

In 2014, a project was started to develop a new Canadian Electrical Code Part 2 standard focused on the electrical equipment of machines. There were already two Part 2 standards in existence that covered Industrial Control panels, but not specifically controls associated with machinery: CSA C22.2 No. 14, Industrial Control Equipment, and CSA C22.2 No. 286, Industrial control panels and assemblies.

This new standard, entitled “Industrial Electrical Machinery”, is aimed at the same types of equipment covered by NFPA 79 and IEC 60204-1. Here’s the scope of the new standard:

1 Scope

1.1

This standard applies to interconnected mechanical systems of industrial electrical and electronic equipment operating in a coordinated manner.

1.2

This standard applies to equipment rated at not more than 1000 V intended to be installed and used in non-hazardous locations in accordance with the rules of the Canadian Electrical Code, Part I.

1.3

This standard applies to equipment that is:

  • permanently installed
  • mobile
  • relocatable, or
  • self powered.

1.4

The industrial equipment covered by this Standard is intended for use in an ambient temperature of 0 °C to 40 °C.

1.5

This standard does not specify additional and special requirements that can apply to electrical equipment that:

  • is intended for use in open air (i.e. outside buildings or other protective structures);
  • will use, process, or produce potentially explosive material (for example paint or sawdust);
  • is intended for use in potentially explosive and/or flammable atmospheres;
  • has special risks when producing or using certain materials;
  • is intended for use in mines

1.6

This standard does not apply to equipment portable by hand while working

1.7

This standard does not apply to self-propelled work platforms

1.8

This standard does not specify additional and special requirements that can apply to electrical welding equipment within the scope of CSA C22.2 No. 60 or CSA/CAN E60974-1

1.9

This standard may be used to supplement but does not replace requirements that already exist in a published CSA component standard

If you are interested in seeing the rest of this standard before it’s published, you’re in luck! It’s available on CSA’s Public Review site until 6-Aug-16. You can read and comment on the document using that system, and all of your comments will be reviewed and dealt with by the task group that created the document. If you are not already registered there, you will have to set up a free account, but that only takes a couple of minutes to do. That also gives you access to all of the other standards that are out for public review, so if your interests are broader than just electrical or machinery, you can have a look at any of the others as well.

Is No. 301 needed?

I question the need for this standard, as I believe that the existing standards already cover this type of machinery more than adequately and that all CSA needed to do was adopt IEC 60204-1 and IEC 61439, however, at this point, I am one lone voice.

If you agree with me, please make your voice heard through CSA’s Public Review system. On the other hand, if you like what the document is about, then please support it.

New Directions in Plastics Machinery

Canada’s Participation in ISO TC 270

SCC Standards Council of Canada LogoIn February of 2016, Canada formed the SCC Mirror Committee (SMC) to ISO TC 270, Rubber and Plastics Machinery. This international technical committee is currently developing ISO 20430, the first international plastic injection moulding machine standard. Until the publication of ISO 20430, two standards have been fighting for dominance: EN 201, Plastics and rubber machines — Injection moulding machines — Safety requirements, and ANSI B151.1, American National Standard for Plastics Machinery – Horizontal Injection Moulding Machines – Safety Requirements for manufacture, Care and Use.

Canada has a strong plastic and rubber industry, with key equipment manufacturers like Athena Automation, Husky Injection Molding Systems, Mold Masters and GN Plastics among others producing world class machinery for the industry. The industry is represented nationally by the Canadian Plastics Industry Association. Despite this, Canada has never had its own standard for this type of machinery.

Involvement in ISO TC 270 allows Canada’s plastics industry to have a voice in developing the international standards for the machinery they design and build, and which ever more commonly, they buy and use.

The committee needs your help to know which way Canadian industry wants us to focus our efforts as the work on ISO 20430 wraps up in coming months. We have a short survey, just three questions long, where you can rank five possible topics we can focus on. We will be submitting our committee vote in early August on the topic, so you have a month or so to answer the questionnaire. Let us know your preferences.

Why now?

ISO LogoUntil the publication of ISO 20430, two standards have been fighting for dominance: EN 201 in Europe, and ANSI B151.1 in North America. Until the relatively recent formation of ISO TC 270 in 2012, there were NO international standards for this type of machinery. While there have been some efforts to harmonise the European and ANSI standards, there are still some significant gaps between these standards. In addition, ANSI’s B151 committee has a number of additional standards for auxiliary equipment for items like robots designed to unload molds, that are not directly addressed in EN standards.

Canada was given a chance to participate through our ongoing friendship with ANSI and the USA, so between 2012 and 2015, Canadian delegates attended ISO TC 270 working group meetings informally, and put Canada’s perspective forward through the US ANSI TAG committee, but in 2016 it became clear that we needed to form our own committee. If you are involved in the industry and you are a member of one of these general groups and would like to get involved with standards development, please go to our recruiting page and join us!

Workplace Risk Assessment – CSA Z1002: Love it, Hate it, Tweak it

CSA Z1002 CoverThe CSA Z1002 TC Needs to Know: Love it, Hate it, Tweak it?

We need to know: Do you Love CSA Z1002? Hate CSA Z1002? Does it need some tweaking? We have a survey so you can let us know!

The First of Its Kind

In 2012, CSA published the first OHS Risk Assessment Standard of its kind: CSA Z1002, Occupational health and safety — Hazard identification and elimination and risk assessment and control. This standard has been in use in Canadian workplaces for four years now, and the Technical Committee is considering the need for updates and improvements to this important standard.

Key to the Z1000 Family

Z1002 is a key member of the Z1000 OHS Management System family of standards because it provides a central tool used in all of the other standards: Risk Assessment. Because it holds this central role, it’s important that it work smoothly and effectively, providing the kind of information that all of the other standards need to do their parts in reducing workplace risk.

The origins of Z1002 come from the machinery safety world where risk assessment is well developed, but the methods presented were broadened to allow their use in many other areas. Were they broadened enough? Could they be improved? These are important questions!

Influencing Other Standards

Shop Floor Hazard Identification
Shop Floor Inspection

The Significance of Z1002 in the Z1000 family has given it additional influence in other CSA OHS standards, including CSA Z432 Safeguarding of Machinery, CSA W117.2 Safety in Welding, Cutting, and Allied Processes, and even in CSA Z614 Children’s Playspaces and Equipment! This kind of influence puts even greater pressure on the standard, and the Technical Committee, to provide the kind of solid, reliable guidance needed.

The Second Edition

In order for the Technical Committee to move on to revising the standard and producing a Second Edition, we need input from the user community. We have heard a bit from some users, but we really want to hear from YOU. CSA has created a very brief survey that you can take to let the TC know how you are using the standard, if it’s doing the job for you, and what you think needs trashing, polishing, or tweaking. We REALLY want to hear from you, so please, take a few minutes and answer the survey! You’ll feel all warm and fuzzy because you did, and we’ll get some good ideas about what to do with the future edition of Z1002! Sound like a good deal? I thought so!
