COMMERCE BUSINESS DAILY ISSUE OF JUNE 28,1995 PSA#1377U.S. Postal Service, Automation Purchasing, 8403 Lee Highway,
Merrifield, Virginia 22082-8150 39 -- ENVELOPE REFLECTANCE METER Sol. AP007. Contact Point, Evelyn
Hunt, FAX (703) 280-8412. The United States Postal Service is currently
using reflectance meters for measuring the background reflectance of
mailpieces as well as the contrast ratio between the ink used for
printing the address and/or barcode, and the background. The United
States Postal Service is seeking sources for an instrument to replace
the existing meters, the ERM-2s. Please note that this is not a Request
for a Proposal (RFP) at this time, the USPS is seeking sources only.
The following is a summary of what is being sought. The existing meters
are portable, stand alone units. Each unit has a calibration standard
used to self calibrate the meter prior to usage. The meters measure
reflected light in both the green and red spectra. The illumination
system is incandescent at 40 - 0 -40 degrees to the horizontal. The
aperture is 0.006 in. wide by 0.010 in. length. The new envelope
reflectance meters may be modified off-the-shelf colorimeters or
spectrophotometers. Absolute accuracy and repeatability within the
meter as well as reproducibility between meters is of paramount
importance. As a minimum, after initial warm-up and self calibration,
the meter shall measure secondary calibration standards with a
measurement repeatability within plus or minus one percent of the
initial readings over a period of eight hours without requiring
additional calibration. The measurement of primary and secondary
standards between any meters shall be within plus or minus two percent.
The vendor shall specify the minimum time before the meter is expected
to require factory recalibration. The spectral response shall match as
closely as is practicable the spectral response in both spectra (red
and green) of the present envelope reflectance meter. The Postal
Service will provide the special characteristics of the present
envelope reflectance meters upon request. The meter shall measure
within plus or minus two percent of the values obtained from a
calibrated reference meter, supplied by the Postal Service, when
measuring secondary standards of various colors. The vendor shall
provide a description of their instrument certification procedures
including traceability to the National Institute of Standards and
Technology (NIST. To be compatabile with the present ERM-2, the meter
shall have a forty five/zero/forty five degree illumination
(influx/efflux). It is mandatory that the aperture have the same
dimensions as that of the present envelope reflectance meter namely,
six mils, by ten mils. (0.006in. x 0.010in). A portable unit while
desirable, is not mandatory. All interested parties must respond in
writing to Ms. Evelyn Hunt at fax no. (703)280-8412, or by mail at
USPS-Automation Procurement, 8403 Lee Highway, Merrifield, VA
22082-8150, Attention: Ms. Evelyn Hunt. Additional information packets
(spectral characteristics, etc.) will be distributed to those
interested parties, with additional instructions. Responses must be
submitted no later than July 14, 1995. Telephone inquiries will not be
accepted. (173) Loren Data Corp. http://www.ld.com (SYN# 0382 19950627\39-0001.SOL)
