Product Information Required to Start Approval Process

Moe Lamothe, P.Eng, Lamothe Approvals Inc.

Please use this checklist to ensure that all necessary information has been compiled and sent to our office.  Not sending the requested information will result in delays and the possibility of additional charges. Remember, you are paying the agency to test, not be installers or equipment operators!

 

1.  Samples: We will require the following items for testing:

1.      Samples of the equipment to be approved.

2.      Power supplies: one additional power supply should be provided.

3.      Transformers: extra samples for abnormal tests (short and overload outputs).

-      If current protection is on either the primary or secondary sides of the transformer (or both), we require 2 samples of the transformer and at least 5 samples of each protector.

-      If thermally protected by a self-resettable switch, we require 2 samples of the transformer.

-      If thermally protected by a ‘single-shot’ switch, we will require at least 5 samples of the transformer.

Note: the above numbers are for single output transformers.  If your transformer has multiple outputs, please contact us for the number of transformers required for testing.

4.      Modems: additional sample for fire overvoltage testing.

5.      Components likely to fail (fuses, lamps, etc).

 

2.  A bit of information regarding your equipment (also complete the attached product information sheet):

This could be a descriptive sales brochure, or a manual.  All agencies require a brief description of the product that they are approving, so tell us about your equipment!

-     What it does.

-     Identify it’s inputs and outputs (with ratings).

-     Tell us if the equipment will run at full-load conditions on it’s own, or if we need to add additional loading.  How much loading is required, and on which outputs?

 

3.  Manuals:  We require manuals (i.e. installation and operating manuals).  Keep in mind the following:

-     Wall mounted equipment: mounting instructions and mounting parts in order to test the procedure.

-     IEC 61010-1 equipment (measurement, control or laboratory equipment): there are requirements for the manual, so make sure you comply with clause 5.4 in IEC 61010-1!

-     Installation instructions for permanently connected equipment.

-     Special instructions, warnings or replacement part info.

 

4.  Equipment markings: All markings must be supplied.  This includes both labels and silk-screening used on the equipment:

-     Marking label (including model number, serial number, ratings, etc.).

-     Fuse label (if not part of marking label).  Be sure to use the fuse symbol!

-     Output identification markings (identification of ports).

-     Warning statements.

We will require a sample of the markings for testing, and in electronic format for the report.  We can read a variety of formats including .jpg, .tif and .bmp.

 

5.  Schematics are generally sent to the agency as part of the report.  We require these schematics in an electronic format and are able to read a variety of formats including AutoCAD, PDF and picture formats (.jpg, .tif, etc).  Printing the schematic to a post-script printer (select file) will also work.  We will require schematics for the following:

-     Primary electrical schematic or block diagram.

-     Low voltage (less than 30Vac and 60Vdc) input schematic.

-     Telecommunication interface schematics.

-     Battery schematics (for ALL types of batteries…including lithium batteries).

-     Secondary schematics showing any current protection (i.e. on output ports).

 

6.  Critical Component List: This list must include all the components that are relied upon for safety (required information includes manufacturer, model number, ratings and approvals (CSA, UL, VDE, TUV, etc.):

-     Primary electrical components (input modules, line filters, fuses, fuse holders, power supplies, transformers, switches, wires, power cords, etc.).  Remember to include all components providing isolation (transformers, power supplies, relays, optocouplers, etc.) or protection (fuses, polyswitches, MOV’s, etc).

-     Low-voltage input equipment: all input components (DC/DC converters, terminal block, etc.).

-     Telecommunication components (fuses, varistors, transformers, capacitors, etc.).

-     ALL high voltage parts (parts greater than 30Vac and 60Vdc).

-     Any components used that provide protection (secondary fuses, relays, MOV’s, etc.).

-     Any plastics used that will form part of the enclosure that supports or is close to electrical components (include flame rating).

-     All fans and fan filters.  Include CFM rating for fans and flame rating for filters.

-     Any component that is approved by an agency (motors, modems, etc).

-     Any larger component (electrolytic capacitors, solenoids, batteries, lamps, etc.).

Assemble the information in a table with the following headings.  The following is an example:

7.  Certified/Listed/Recognized Components.  License copies are required for:

-     All components providing isolation (such as power supplies, optocouplers, transformers, DC/DC converters, relays and modems).

-     All primary components (such as line filters, AC fans and switches). 

-     Note: For UL recognized power supplies and dc/dc converters: obtain a copy of UL’s conditions of acceptability for these components.

 

8.  Uncertified/Unlisted/Non-Recognized Components: These components will have to be examined separately to ensure compliance as part of your equipment.  If the component is critical and is only marked, a copy of the CE report (80+ pages) may be adequate, but it is at the agency's discretion if they will accept it.  Additional testing and investigation may be required.  

The following components are often found under this category:

-     Transformers: a cross-sectional drawing and specifications (windings, turns, core, insulation type, insulation thickness etc.) along with an ‘unpotted’ sample of the transformer must be submitted.

-     Power supplies: specification sheets with ratings, description of inputs and outputs, including transformer construction details and samples (see transformers above).

Unless specifically identified in the quotation, evaluation of non-approved components will be charged in addition to the quoted amount.

 

9.  Creepage Distance and Clearance Measurements: These are easily measured in the equipment in most cases, but gets tricky (impossible) on a multi-layer printed wiring board.  If your equipment contains components and traces that are required to be isolated (such as primary, TNV or high voltage circuits), we will require 1:1 colour coded artwork for that printed circuit board (choose one colour for the primary, TNV or high voltage, one colour for low voltage parts and one colour for ground). 

This is typically done for uncertified/unlisted/non-recognized modem boards, power supply boards, and high voltage boards.
