Did you know that ASTM D6617 Standard Practice for
Laboratory Bias Detection Using Single Test Result from Standard Material
allows you to determine an acceptable tolerance zone and demonstrate if
your laboratory is performing a test method without bias?

ASTM D02 has revised ASTM D975, Standard Specification for Diesel Fuel Oils based on
the activity from last semester. The
latest issue is D975-09 to be electronically published after final
proofing. It will most likely be
electronically published this month.
One major modification is the addition of D7170 Determination of Derived Cetane
Number (DCN) of Diesel Fuel Oils—Fixed Range Injection Period, Constant
Volume Combustion Chamber Method as an alternate method to ASTM D613.
|
Waukesha FIT –
the
world’s simplest DCN
|
 
|
With the inclusion of ASTM D7170 into ASTM D975, we’d like
to take this opportunity to introduce you to the World’s Simplest DCN unit.
It’s simplicity itself with virtually no hands-on manipulation of the
instruments.
1. Pour
in your sample
2. Click
Run
3. and
out comes the answer.
Only the spacing-saving compact bench top Waukesha FIT
unit has unmatched precision with no bias and no carry over effects from
previous samples.

Application Note – Strama-MPS FZG
Calculation of Slow Speed Wear of Lubricated Gears
|
This Technical Paper is available from Compass
Instruments and Strama-MPS. It was
written by H. Winter and presented by J. Plewe at the AGMA Fall Meeting,
October 11-13, 1982.
Summary
On gear drives running with pitch line velocities below
0.5 m/s, so called slow speed wear is often observed. To solve some problems, extensive
laboratory test work was started 10 years ago. A total of circ. 300,000 h
running time on FZG –back-to-back test rigs have been run in this speed
range. The test results showed a
correlation between calculated EHL Film thickness and a wear
coefficient. Based on these experimental
results and some wear data of different size industrial gear drives, a
method for calculating slow speed wear was derived and is presented in this
paper.
To calculate the service life of slow speed gears, the
limits of wear for different modes of failure are discussed. Design guides to increase slow speed wear
load capacity are presented.

eralytics™ ERAVAP EV02
– the future
is now!
|
![MCj01051880000[1]](2009v2n2_files/image034.png) 
|
eralytics GmbH and Compass Instruments are pleased to
announce the immediate availability of the NEW EV02 for LPG vapor
pressure testing by ASTM D6897.
With the addition of the EV02 to your lab, you can run
LPG VP and gasoline D5191/D6378 RVP on the same instrument.
Why settle
for the same old interface and limited functionality when you can have the
future now.
