New CSA Standard for Machinery Electrical Equipment

Electrical Equipment of Machinery

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 coördin­ated 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!
