He does consume a lot of strange material plastics, metalized thread, rubber, etc. It is the responsibility of the user of this standard to establish appropriate astj and health practices and determine the applicability of regulatory limitations prior to use.

This ast method provides a measure of the presence of surfactants in aviation turbine fuels. DBP Holding consists of three companies: These ratings are approximately the same as those obtained using Test Method D Perma Pure LLC, a global leader of gas conditioning solutions for medical, scientific, and environmental monitoring applications, today announced that the Company will be exhibiting at PittconMarchd348 Chicago, IL.

In addition, they also go to work with all their energy in road and rail vehicles, yachts and work Values obtained outside of those limits are undefined and invalid. The production hall for pre-treatment, powder coating and new water treatment.

The combined events are expected to feature 5, exhibitors and overattendees from They can also detect surface active substances added to or picked up by the fuel during handling from point of production to point of use. Customer comments No comments were found for ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer. ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer 0.

This event, which takes place in connection with the MEDICA conference and exhibition, brings together medical equipment industry leaders to demonstrate new asttm and solutions.

Historical Version s – view previous versions of standard. These ratings are approximately the same as those obtained using Test Method R3948 Some of these substances affect the ability of filter separators to separate free water from the fuel. Surfactants degrade the performance of filter separators used to remove water from the fuel. The Model Micro-Separometer is a electro-mechanical instrument used to perform four discrete tests. Like Test Methods D and D, this test method can detect carryover traces of refinery treating residues in fuel as produced.

Values obtained outside of those limits are undefined and invalid.

The sample in the vial is discarded and the vial is retained. The material was subsequently removed during the coalescing portion of the test, thus, the processed fuel had a atm light transmittance than the aztm sample used to obtain the reference level resulting in the final rating measuring in excess of The vial is placed in the turbidimeter and the meter is adjusted to Test method selection is dependent on the particular fuel to be tested.

Certain additives can also have an adverse effect on the rating. Historical Version s – view previous versions of standard Translated Version s: The higher the rating, being the maximum, the less surfactant present. The processed fuel is discarded and a portion of the unprocessed fuel is placed in the vial, which is re-inserted in the turbidimeter.

Test Method D passes a portion of the sample through a filter medium, which is collected in a clear glass, vial. In the event a value greater than is obtained, there is a good probability that light transmittance was reduced by material contained in the fuel used to set the reference level.

Give D9348 A Call! The presence of water can impair engine performance and initiate microbiological growth, which can cause corrosion in tanks and filter plugging in fuel lines.

The material was subsequently d9348 during the coalescing portion of the test, thus, the processed fuel had a higher light transmittance than the fuel sample used to obtain the reference level resulting in the final rating measuring in excess of Get Updates From Emcee delivered to your inbox.

The values given in parentheses after SI units are provided for information only and are not considered standard. Table 1 identifies the recommended test method for various fuels.

*ASTM D Emcee Electronics

The emulsion is passed through the filter at a programmed rate and a portion is collected in the retained vial. The Micro-Separometer has a measurement range from 50 to Test method selection is dependent on the particular fuel to be tested. No comments were found for ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer. Table 1 identifies the recommended test method for various fuels.

For quality control purposes, water separation characteristics of fuels are rated to determine the amount of surface active materials surfactants present.

PORTABLE MICROSEPAROMETER ASTM D

In the event a value greater than is obtained, there is aztm good probability that light transmittance was reduced by material contained in the fuel used to set the reference level.

Be the first to comment! The primary difference between the modes of operation is the rate of fuel flow through the fiberglass coalescing material.

Test Method D, D and D employs the use of a turbidimeter, a mechanical mixer, and a disposable coalescer filter. Certain additives can also have an adverse effect on the rating. A container of distilled water is also included in each Six Pack to perform water separation tests.

The value obtained is compared to the unprocessed sample that was used to set the meter to They can also detect surface active substances added to or picked up by the fuel during handling from point of production to point of use.
