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.

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

K394XX Water Separability Tester

K394XX-Manual -2-
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

1 Introduction
The Koehler Water Separability Tester is the
latest design for performing the ASTM D1401
test method and related test specifications.
The ability of a lubricating oil to separate from
water and resist emulsification is an important
performance characteristic for applications
involving water contamination and turbulence.
Water Separability is determined by stirring
equal volumes of water and sample together at
a controlled temperature to form an emulsion
and observing the time required for separation of
the emulsion to occur. This method is suitable
for petroleum oils and synthetic fluids
This manual provides important information
regarding safety, technical reference, installation
requirements, operating condition specifications,
user facility resource requirements, and
operating instructions for the Water Separability
Instrument and Data Acquisition Software. This
manual should also be used in conjunction with
applicable published laboratory procedures.
Information on these procedures is given in
section 1.2.
