Introduction



Almost every industrial sector is
influenced in some way by activities in
other parts of the world
Standards have a role in nearly every
conceivable industry, from power tools
and appliances to automobiles to
homeland security and most importantly
transformers
Global impact of a standard should be
carefully considered during its
development and implementation
Global Standards





International standards contribute to making
the development, manufacturing and supply
of products and services more efficient, safer,
and cleaner.
Make trade between countries easier and
fairer.
Provide governments with a technical base
for health, safety and environmental
Aid in transferring technology to developing
countries.
In general, international standards serve to
safeguard the consumers and users of
products.
Global Standards Development
Developing a standard that will be
accepted and implemented on a
global scale is not easy
 Things to consider

 Cultural
differences
 Regulatory requirements
 Market requirements

True test of an international standard
is whether it is actually used globally
Global Relevance
•
•
•
Broad effort in international
standardization that embraces a more
inclusive approach.
Taking into account the needs of all
countries.
Considering the differences in
•
•
•
•
Infrastructure
Environment
Social differences during standards
development.
Affects the technical design of products
as well as testing and the rating
procedures which need to be repeatable
and reproducible all over the world.
International
Electrotechnical
Commission (IEC)
IEC states the following
 “the desired characteristic of an
international standard is that it can
be used or implemented as broadly
as possible by affected industries
and other stakeholders in countries
around the world”

Development of an IEC Standard
 PWI
 NP
 CD
 CC
 CDV
 FDIS
 Published
Standard
 IEC General
Potential New Work Item (PWI)
 Proposer
can be:
 National Committee (NC)
 Secretary
 Liaison organization
 General Secretary
New Proposal (NP)
Approval process
simple majority of members (51%)
at least 5 experts to be nominated
 Rejected
End of work
 Approved
Becomes new work item proposal
(NP)

New Work Item Proposal
(NWIP)
3 month vote
 Nominate experts and project leader
 Working Draft (WD) within 6 months
after initiation
 Working Group (WG) is disbanded

Committee Draft (CD)
Committee Draft circulated to National
Committees
 Circulation time

 First
CD, at least 3 months, no more than 6
months
 Subsequent CDs 3 months

National Committees submit comments
Compilation of Comments (CC)
Editorial comments: Secretary makes
changes
 Technical comments:

 Discussed
with technical chairman and/or
project leader
 Revised CD
 CD out again for comments; 3 months
maximum
Committee Draft (CD) Maturity
Mature means that the draft has
reached technical consensus
 Maximum cumulated total time: 24
months

Committee Draft for Vote (CDV)
CDV goes out for 5 month vote
 National Committees vote

 One
vote per country
 Votes: positive, negative, or abstention
 P-members - participating (vote counts)
 O-members - observing (can only
comment, cannot vote)
Committee Draft for Vote
(continued)

CDV approved if
 2/3
majority vote positive
 Not more than 1/4 votes are negative
 Abstentions and negative votes without
technical reasons are not counted
Resolution of comments
 Preparation of final manuscript by
secretary

Final Draft International Standard
(FDIS)
Maximum cumulated total time: 3 years
 Two month vote

 Positive:
published IEC standard within two
months after voting ends
 Negative: back to Technical Committee
(TC)

FDIS approved if:
 2/3
majority vote positive
 Not more than 1/4 votes are negative
Systematic Review of
International Standards
Every standard reviewed every five years
 Maintenance Procedures

 Amendments/revisions
to existing standards
 Maintenance teams (working groups)
 No new work
 Maintenance cycle - same document flow
 CD
> CDV > FDIS
 Results in revised or amended publication
 Cycle
time agreed by the Technical Committee
IEC General
Central Office (CO) Geneva, Switzerland
 All documents must be electronic
 Internet: www.iec.ch
 New numbering system

 ISO
from 1 to 59999
 IEC from 60000 to 79999
IEC - Transformers
IEC 61558-1
 EN 61558-1
 TC 96
 20 P-member (10 O-member) countries
 Current TTA (US) Members

 Mitch
Rhine - Signal Transformer
 Jeff Brown - Cramer Coil & Transformer Co.,
Inc.

Loss of UL US TAG Representative
IEC – TC 96
Scope: Standardization in the field of safety
and EMC of transformers, reactors, power
supply units, and similar products for low
voltages up to 1100 V a.c. and a rated
frequency up to 100 MHz.

Power Tool Institute



The Power Tool Institute is the preeminent
trade association for power tools.
Its members represent all of the major
market-leading brands in the areas of
portable and stationary, including
cordless power tools.
Major areas of focus are
 Safety
 Education
 Standards
 Legislative

PTI’s Global Standards Story
•
•
•
•
WHY?
All of the companies are global.
All manufacture and sell worldwide.
Cost Savings
•
•
•
•
•
•
•
•
One Design
Easier to manufacture
Flexibility
Purchasing (larger volumes) (better discount)
One test (CB Scheme) accepted by all
European Power Tool Association (EPTA)
Japanese Equipment Manufacturer’s
Association (JEMA)
UL / CSA Binational experience
The Story - Standards
•
•
Began in 1999
Tools - 4 main categories
•
•
•
•
•
Portable (IEC 60745)
Transportable (IEC 61029)
Cordless (IEC 62043)
Garden (IEC 60335)
International Electrotechnical
Commission (IEC) - SC61F
The Story
•
Decide to start with portable
tools
•
•
•
•
•
Easiest
High probability of success
Assembled of team of standards
engineers from PTI, EPTA, &
JEMA
Became the Working Group
Meetings alternated between
USA/Europe
Challenges
 Each
group had different standards
with a long safe track record and a
history of users preferences
 Politics
 Have to remember that most of the
people were from the same
company – just different parts of
the world
 MUST be driven with the support of
top management
Group Power
 USA
through PTI applied for the
IEC SC 61F Secretariat
 Bosch Germany became the IEC SC
61F Secretariat Chairman
 These individuals held positions
within CENELEC (EN standards for
Europe)
 Pursued Parallel Voting – at the
CDV level the IEC and EN are the
same and jointly reviewed.
The Group






The group begins to work together.
Everyone had the same goal – SAFETY.
Numerous battles fought during the
meetings.
At the end of the day, all were friends and
relationships formed.
Group transforms from an industry group
to include UL, CSA, Government Safety
Officials
Became an IEC Maintenance Team(s)
Three Years Later (2002)
IEC 60745-1: Released the 3rd edition
– incorporates a combination of
UL/CSA, EN & IEC standards.
 IEC 60745-2s (22): Released over the
next year to complement IEC 607451.
 Example of consensus not reached

 60745-2-5
Circular Saws
 Both style products in Standards
 Marketplace will pick the “winner”
2002-2005
•
•
•
•
•
•
Decided to incorporate the
cordless tools as an annex to
IEC 60745
Eliminated the separate cordless
standard (IEC 62043)
Saves future maintenance and
work
Released 2 amendments to IEC
60745-1, Edition 3
Released IEC 60745-1 Edition 4
Updated numerous 60745-2s
Currently
•
•
•
•
•
•
•
IEC 60745-1 Edition 5
Incorporates IEC 61029 & IEC 60335
Committee Draft (CD) just released
Saves manpower
Saves time
Easier to maintain
Aligns with EN and manufacturer’s
interest
Next Steps
Create IEC 60745-2s to update to IEC
60745-1 4th edition by Maintenance Team 4
 Create IEC 61029-2s (10) to update to IEC
60745-1 5th edition by Maintenance Team 4
 Create IEC 60335-2s (7) to update to IEC
60745-1 5th edition by Maintenance Team 3
 5 more years until completion
 Then only ongoing maintenance.
