WEEE Directive Compliance Statement

Background
The goal of the WEEE Directive is to encourage design of environment-friendly products that increase reuse,
recycling and other forms of recovery to reduce waste streams and applies to listed Electronic and Electrical
Equipment (EEE) and Koehler's equipment falls broadly into Appendix 1A; Section 9 Monitoring and Control
Equipment: Measuring, weighing or adjusting appliances for household or as laboratory equipment.

Any associated non-embedded equipment such as Lighting (Saybolt Color) and PCs/Printers also fall under
WEEE. If provided with an order these ancillary items must be WEEE compliant. For these and other reasons
(printer cartridges are regionalized) the equipment must be supplied through a third party supplier in Europe.

The WEEE Directive applies to electrical and electronic equipment falling under the categories set out in Annex
IA provided that the equipment concerned is not part of another type of equipment that does not fall within the
scope of this Directive. Annex IB contains a list of products which fall under the categories set out in Annex IA.

http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2003:037:0024:0038:en:PDF

We do not qualify for any of the 10 exemption categories.

http://www.dpa-system.dk/en/WEEE/Products/Exemptions

Professional use
For equipment defined for ’professional use’ local authorities have no role to play. Producers and importers are
basically responsible for collection of WEEE recyclables from the professional user and for subsequent
management. A separate statement is given cataloging the items that require separation from the equipment
along with basic information on subsequent processing or recycling prior to disposal of the equipment.
http://www.dpa-system.dk/en/WEEE/Products/Private-or-professional-use

Responsibility for Registration and Annual Reporting:

Koehler will not sell directly to end users in the EU and so has no responsibility to register within each EU state
and to make annual reports. Koehler declares that this responsibility is born by the importer who is the first
level of the distribution chain and is subject to producer responsibility. We will communicate this in writing to
our distributor/importers in the EU stating they are responsible to satisfy WEEE registration and reporting
requirements in the EU states where they conduct sales activities.

It is illegal to market electrical and electronic equipment covered by producer responsibility without being
registered.

http://www.dpa-system.dk/en/WEEE/Producers/Whoissubjecttoproducerresponsibility

Product Design
Koehler's designs allow for complete disassembly to a modular level which usually allows for standard
recycling. A qualified refrigeration system technician must be consulted when disassembling and de-
commissioning any equipment with refrigeration systems.

Koehler's scientific testing equipment is robustly designed to function over a long service life and are typically
repaired many times over the course of years rather than being replaced. We believe that re-use and
refurbishment is the very best form of re-cycling.

All batteries must be readily removable not soldered in place.

Recycling instructions
In the event that replacement becomes necessary, we will include instructions, particularized to each
instrument that informs the customer of their recycling responsibilities and giving them guidance in doing this.
All Koehler equipment has been placed on the market since 13th August 2005 and so Koehler is defined as a
"new WEEE producer". As such we must provide information on refurbishment, treatment, and re-use.

Our instrument manual will include this compliance statement and indicate that any collection of materials will
be handled by their authorized distributor. In the event that the distributor is unreachable or is no longer a
distributor for Koehler Instrument, Co., other arrangements may be made including accepting the materials
directly.

Recycling is free of charge. Shipping is the responsibility of the end users. Whether shipping to a distributor or
to Koehler directly, safe, properly declared, and labeled packaging and shipping expenses are the sole
responsibility of the end user.

WEEE Marking

Since Koehler products are subject to the WEEE Directive we must display the WEEE symbol shown above in
accordance with European Standard EN 50419 on the equipment. It must be indelible, at least 5mm in height,
and clearly legible. If the equipment is too small the mark must be in the product literature, guarantee
certificate, or on the packaging. Rules on marking are established in section 49 of the WEEE Order.

Koehler Instrument Company, Inc.

c/o RECYCLING
1595 Sycamore, Ave.
Bohemia, NY 11716

As a minimum the following substances, preparations and components have to be removed from any
separately collected WEEE:
- Mercury containing components, such as switches or backlighting lamps (compact fluorescent lamps, CFL),
- Batteries
- Printed circuit boards if the surface of the printed circuit board is greater than 10 square centimeters (about 4
sq in.),
- Toner cartridges, liquid and pasty, as well as color toner,
- Chlorofluorocarbons (CFC), hydrochlorofluorocarbons (HCFC) or hydrofluorocarbons (HFC), hydrocarbons
(HC)
- Liquid crystal displays (together with their casing where appropriate) of a surface greater than 100 square
centimeters and all those back-lighted with gas discharge lamps,
- External electric cables
- Components containing refractory ceramic fibers as described in Commission Directive 97/69/EC of 5
December 1997 adapting to technical progress Council Directive 67/548/EEC relating to the classification,
packaging and labeling of dangerous substances (2),
- Electrolyte capacitors containing substances of concern (height > 25 mm, diameter > 25 mm or
proportionately similar volume)

2. The following components of WEEE that is separately collected have to be treated as indicated:
- Equipment containing gases that are ozone depleting or have a global warming potential (GWP) above 15,
such as those contained in foams and refrigeration circuits: the gases must be properly extracted and properly
treated. Ozone-depleting gases must be treated in accordance with Regulation (EC) No 2037/2000 of the
European Parliament and of the Council of 29 June 2000 on substances that deplete the ozone layer (4).
