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.

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).

Low Temperature Torque Apparatus
Operation and Instruction Manual
K18854,55,64,65-Manual -9-
1 Introduction
The Koehler Low Temperature Torque
Apparatus determines the extent to which a
sample grease retards rotation of a test bearing
when subjected to low temperatures. A grease
sample is packed into an automotive wheel
bearing or a slow speed ball bearing and cold
soaked at the test temperature. The spindle
(automotive grease) or inner bearing ring (ball
bearing grease) is then rotated at 1 RPM while the
restraining force on the test rig is measured and
displayed digitally. Torque values calculated from
the force determinations measure the viscous
resistance of the grease. Models equipped with
the optional data acquisition system provide a test
record for reporting purposes.
This manual provides important information
regarding safety, technical reference, installation
requirements, operating condition specifications,
user facility resource requirements, and operating
instructions for the Low Temperature Torque
Apparatus. This manual should also be used in
conjunction with applicable published laboratory
procedures. Information on these procedures is
given in section 1.2.
