  • November 1st 2008 - SEL moved into a much larger facility which significantly increases the size and capability of our test lab. We are located in the same office complex at 2370-D Qume Drive, San Jose, CA 95131. Many companies which have traditionally had their own test facilities are now finding it impractical due to the increased costs of maintaining ISO 17025 accreditation. Companies that would like to maintain the benefits of running their own tests, but no longer want to pay for the costs of maintaining ISO 17025 accreditation can now utilize our new facility. Think it of a lab timeshare, where you use it when you need it! SEL maintains full calibration and provides the equipment necessary to complete your work in a timely fashion.

    Some of the other benefits to the new space are:
    • Increased number of tests that can be done simultaneously.
    • Room for testing large equipment.
    • Improved security
    • More convenient setting for testing with agency engineers
    • Separate standards library
    • Client work areas
    • Wireless internet access for guests


EN 60950-1 (2006), 2nd Edition
Be aware of the following amendments published to 60950-1 2nd edition: A1, A11, and A12 on the following effective dates:

EN 60950-1/ A1:2009 : March 1st, 2013

EN 60950-1/ A12: 2011 : January 24th, 2013

New Requirement for 10 amp Swiss Plug: SEV 1011:2009

In an effort to decrease the number of injuries due to electrical shock, all 10 amp (Type 11- 2 pin, 10A, and Type 12- 3 pin, 10A) Swiss plugs will be required to have partially insulated line and neutral pins. Current non-insulated 10 amp plugs can be used until December 12th, 2012. After December 31st, 2012, non-insulated Type 11 and Type 12 plugs can no longer be imported into Switzerland. As of January 1st, 2013, all electronics must accommodate these partially insulated plugs. By December 31st, 2016, all products with non-insulated style plugs will no longer be sold or allowed to be in stores. Click here for complete information.

Machinery Directive 2006/42/EC.
On December 29th, 2009, the new Machinery Directive went into effect, without much of a transition. Here is a link to more information.

IEC 60825-1 (2007), 2nd Edition for Laser Devices Published!
Noticeably, LED's were removed from the scope of this standard, although LED's will still be regulated by the EU, and IEC standards, only in other standards. Laser Notice 50 in the US explicitly allows this latest edition of the standard for the least burdensome approach to laser compliance.

UL 60950-1 (2007), 2nd Edition for Information Technology Equipment Published!
This standard was published 3/27/07, but has not been often used yet in practice. It does fix some of the issues left from the 1st edition, including some clarification to Section 7 with regard to evaluating CATV connections. There will be some reading and rereading for leakage current requirements which have changed. There are certainly some significant changes to items like trace to trace spacings internal to a circuit board.

UL 60950-22 (2007), 1st Edition for Information Technology Equipment Installed Outdoors Published!
This was published in early 2007 and was based on the IEC version from 2005. It is a compilation of the IEC standard (mostly), the traditional requirements of UL50, and UL's Bulletin for Outdoor Equipment (2001).

Laser Notice 50 Re-Issued June 24th, 2007 by the CDRH
This re issuance essentially re-affirms the previous Laser Notice 50, but updates to the more recent IEC standards. Importantly, this can affect product's labeling with regard to the Notice's publication date!

Originally, on May 27th, 2001, in its effort to harmonize with the international requirements, the CDRH issued Laser Notice 50 to inform manufacturers that IEC60825-1, with Amendment 2, may be used as an alternative compliance method to 21 CFR 1040.10 and .11. Some of the original requirements of those Regulations still apply and the details are summarized by Clause in the Laser Notice. Ultimately the CDRH might amend the Federal Regulations, but for now, and the indeterminate future, Notice 50 establishes a harmonized solution.

IEC 60950-1 (2005), 2nd Edition for Information Technology Equipment Published
This standard is an update that fixes some of the problems with the 1st edition. As far as we know, in 2008, there are very few power supply vendors actually certifying to this new standard. We thought that the IEC/CB Scheme is supposed to require the latest standard the moment it is published, and here we are a couple of years later. There are some additional requirements for leakage current, particularly for products with multiple/redundant power inputs.

Laser Notice 54 Issued January, 2006 by the CDRH
Many manufacturers of Class 1 laser products will be interested in this Laser Notice, which exempts many manufacturers from submitting Product Reports to the CDRH, although these Reports will still need to be prepared.

IEC 60601-1 (2005), 3rd Edition for Medical Equipment Published
This has been in the works for an extremely long time, maybe close to eight years. The adoption as a UL standard and the transition schedule is still being worked out.

IEC 60950-1 (2005), 2nd Edition for ITE, Published in December, 2005
Yes, that is right. There is another ITE standard for everyone to learn. UL60950-1, 1st Edition was published only in 2004, which was not very long ago; however, it was based on the IEC60950-1, 1st that was published back in 2000. So maybe 5 years between IEC versions is not unreasonable. There are some different requirements in this new standard, particularly with regard to leakage current and cable/antenna connections.

IEC 60950-22 (2005) for Outdoor ITE, 1st Edition Published in December, 2005
It was a long time in the works, and even so, there were some very significant changes in the very last revision of the Standard that will effect every manufacturer that makes outdoor Information Technology Equipment! Also there is a UL Bulletin from 2001 that covers this topic, with some overlap.

UL 61010-1, 2nd Edition Published July 12th, 2004
After much delay, the US/Canadian version of IEC61010-1, 2nd has finally been published -- almost 3-1/2 years after the base IEC document was finalized, and 8 months after the European Union mandated the switch to EN61010-1:2001 (2nd). Improvements include the fact that there are not A, B, and C versions for different, specific categories, as the previous 1st edition had. With the delay, we expected there to be more significant US/Canadian deviations from the 1st Edition, which turned out not to be the case!

UL Using Only UL60950/3rd and UL60950-1 for New ITE Submittals?
The option of using UL1950 standard expired on March 31, 2002, after which new product submittals and major revisions to existing products must meet the full requirements of the standard, without relaxations. Products Listed before that date with the relaxations will not lose their approval until March 31, 2005. There are considerably new requirements in the -1, some of which mean certain failure, particularly for CATV products!

IEC 60825-1 Second Amendment Published for Laser Devices, But...
The new Amendment 2 for IEC60825-1 Standard for Safety of Laser Products was published in January of 2001. Among the significant changes are the addition of Laser Classes 1M, 2M and 3R, and some relaxations in the power limit calculations.


UL: (Underwriters Laboratories)

March, 2009:
UL Changes Standards Download Policy on Free UL Standards for UL Customers.
Although the non-IEC based standards are still downloadable for free, due to the IEC's increased licensing fees for the standards, those UL standards that are based on the IEC standards are no longer free to download. Those interested in this should contact UL at 1-888-853-3503, and have their UL Subscriber Number handy (usually 123456-001).

Collaborative Standards Development System Introduced to Encourage Industry Participation!
By having an account on the free standards download system, you can identify which standards, when updated, that you would like to know about. Often the updates to the standards are posted for public comment with a month or so for responses. It is a good way to participate without having to travel to standards' development meetings. Here is a link.

June 28, 2008:
Underwriters Laboratories (UL) has introduced a new holographic UL Mark that will be required in 32 common consumer product areas, including power supply cords, nightlights and ceiling fans.
The redesigned label incorporates cutting-edge technology, elevated security features and a unique hologram design, making it easy to identify and validate, yet incredibly difficult to replicate. The new holographic label will be available for manufacturers on July 1, 2008. It will be required worldwide on all new production in the 32 hologram categories starting July 1, 2009.
For a list of the 32 product categories that require the new hologram, click here

UL Requiring Global Service Agreements (GSA's) to be Signed by All Clients in Early 2008
Many existing UL customers and factories have been requested, in the course of active projects in mid to late 2007, to sign the GSA's, which is UL's latest replacement to the UL FUS Agreements or Service Agreements (or L-40s). Those who did not do so in 2007 will be required to do so in 2008, and we do anticipate this possibly delaying projects in 2008.

UL Requiring Switch-Over from Client Document Access (CDA) to MyHome
Many customers who have been accustomed to using CDA to download their existing UL Reports and Procedures from the UL site, will in 2008 have to start using the MyHome website, which has the CDA as one small component of a larger site. MyHome can be used to manage additional projects, and clients must sign up for the program, which requires downloading, signing and uploading a contract. The MyHome start page is here. UL is updating the features in this area constantly, and some interesting items include a full employee directory with email addresses and direct phone numbers.

UL Moves to New "Value-Based" Pricing System in Mid 2007
In September or so of 2007, UL moved to a different pricing system, where UL's perceived value to the customer drives the costs in the new cost structure. Most agencies, and UL to this point, attempt to price a project based on the effort involved, in "man-hours" typically, to complete the effort. This new approach does result in some traditionally simple efforts costing significantly more that in the past; for example, adding a model still does not require much time to complete, in terms of typing a few keystrokes, but UL considers that if its customers get to benefit from having its mark on the newly added product, that value warrants a charge that is not equivalent to the keystrokes for its inclusion.

UL Allows Free Download of All UL Standards for Existing UL Customers
In early 2007, UL sent out letters to its client base, with usernames/passwords and instructions to download these standards.
To help you find it, an example of the UL letter that went out is shown here.

UL Initiates MyHome for Project Oversight
In 2006, UL started an expanded version of the Client Document Access (CDA), where in addition to downloading UL Reports, there is now additional details about project status.

UL's Santa Clara Office Moved, Renamed Silicon Valley Office
UL in the Bay Area recently moved to a new location after 50+ years in Santa Clara. The Silicon Valley Office is now located in San Jose, California at 455 East Trimble Road. The new main phone number is (408) 754-6500 and the extensions have all changed. Due to the significantly smaller office that does not include any EMI chambers or testing capabilities, UL is outsourcing its EMC testing efforts moving forward.

New UltraLink UL Reports
They are looking a lot like CB Test Reports these days. Your factories should be versed in this new style, to help with the inspection process.

Access Your UL Reports Online!
In 2003 UL launched its Client Document Access (CDA), whereby UL clients can sign up for this free service, and access its UL Reports online, using a standard internet browser. It has its hitches, particularly for the new UltraLink (CB-Style) UL Reports, but overall this program is very nice! Let us know if you are interested in activating this (usually only takes a couple of days!).

UL Component Directory Online!
As of March 24, 2000, the information in the UL "Yellow Books" (a.k.a. Recognized Component Directories) is available online at UL's website, FREE OF CHARGE. Click here for more. Additionally, as of early 2001, the Wire Style pages are accessible through the website, so you can see the "recipe" -- insulation material & thickness, gauge range, etc. -- that UL Recognized wire manufacturers can build to.

Are You Using the Latest UL/cUL Mark?
Starting in November of 1997, UL introduced the new combined mark for UL and cUL evaluations. Please note that the word "LISTED" is to be in the same font as the "C" and "US". Downloadable UL Mark artwork can be found here.

TUV: (TUV Rheinland of North America)

Germany adds Poly aromatic Hydrocarbon (PAH) Testing to GS Mark Requirements.

Effective as of April 1 2008, all electrical and electronics products that are
GS Mark certified will have to comply with new requirements covering
16 poly cyclic aromatic hydrocarbons (PAH's). Previously, this was a voluntary
testing requirement, but now becomes mandatory.
This will include electronic products intended for use in the household or in the workplace.

Certification will require test results demonstrating acceptable levels of PAH on user accessible or handheld material surfaces of products, or where there is apparent odor.

User inaccessible internal parts are not required to be tested.

About PAH's
PAH's are one of the most widespread persistent organic pollutants. Some are known or suspected carcinogens, and are linked to other health problems. Within the group of 16 PAH's that will be tested for, benzo[a]pyrene (BaP) is specially targeted because it is a Class II carcinogen, mutagen and reprotoxin.

PAH's contamination can be found not only in rubber, but also in various plastic materials, such as ABS (acrylonitrile butadiene styrene), PP (polypropylene) and various lacquers/coatings, as well as in treated natural materials. Due to the harmfulness and insufficient controls observed by the market, the verification of the limits of PAH's has become compulsory when applying a GS
certificate and applies to all final products sold with a GS mark, as well as their components. Requirements are based on the revised ZLS standard ZEK 01-08.

Scope of the New Requirements
The following components and materials need to be checked during a PAH examination of products: All (grip) surfaces, which may contain PAH's and that are touched or put into the mouth during intended use or foreseeable misapplication. (Note: It does not apply to definite misuse).
The following materials are examples that could contain PAH's:

  • Elastomer (plastic and rubber material)
  • Black or dark colored polymer
  • Coatings and varnish
  • Materials treated with conservation agents (naphthalene) (e.g. leather products, wood, bast and natural bristle)

TUV Product Service Becomes NRTL in US but Leaves Silicon Valley and Denver!
OSHA's website shows that pending a final audit after TUV Product Services' first NRTL approval, TUV Product Service will become an NRTL, competing with UL, TUV Rheinland, CSA and others. But they will be doing it mostly outside of the Bay Area, as they are leaving their facility in Santa Clara, along with the BABT group.
