The material was subsequently removed 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 The combined events are expected to feature 5, exhibitors and overattendees from In addition, they also go to work with all their energy in road and rail vehicles, yachts and work Some of these substances affect the ability of filter separators to separate free water from the fuel.

The higher the rating, being the maximum, the less surfactant present. Higher ratings, is maximum, indicate that there is less free water and particulate present. 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.

Model 1140 Micro-Separometer

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 PittconMarchin Chicago, IL. The company specialises in the powder coating of steel, hot-dip galvanised steel and aluminium components.

Some of these substances affect the ability of filter separators to separate free water from the fuel. 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.

Model Micro-Separometer: Emcee Electronics

The processed fuel is discarded and a portion of the unprocessed fuel is placed in the vial, which is re-inserted in the turbidimeter. Values obtained outside of those limits are undefined and asfm.

Historical Version s – view previous versions of standard Translated Version s: Selection of Mode A or Mode B depends on the specific fuel and specification requirement. DBP Holding consists of three companies: No comments were found for ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer. Surfactants degrade the performance of filter separators used to remove water from the fuel.

This test method provides a measure of the presence of surfactants in aviation turbine fuels. The production hall for pre-treatment, powder coating and new water treatment.

Link to Active This link will always route to the current Active version of the standard. The vial is replaced in the turbidimeter and the water separation characteristic of the fuel is rated.

MAN Nuremberg cleans industrial wastewater 3 times better Dec. These ratings are approximately the same as those obtained using Test Method D Aastm sample in the vial is discarded and the vial is retained. Like Test Methods D and Dthis test method can detect carryover traces of refinery treating residues in fuel as produced.

In the event a value greater than is obtained, d394 is a good probability that light transmittance was reduced by material contained in the fuel used to set the reference level. Referenced Documents purchase separately Asgm documents listed below are referenced within the subject standard but are not provided as part of the standard. For quality control purposes, water separation characteristics qstm fuels are rated to determine the amount of surface active materials surfactants present.

A portion of the sample, in a clear glass vial, s3948 used to set the meter to read The Model Micro-Separometer is a electro-mechanical instrument used to perform four discrete tests. The material was subsequently removed during the coalescing portion of the test, thus, the processed fuel had a higher ashm transmittance than the fuel sample used to obtain the reference level resulting in the final rating measuring in excess of These ratings are approximately the same as those obtained using Test Method D 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.

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

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Test method selection is dependent on the particular fuel to be tested.

*ASTM D Emcee Electronics

The emulsion is passed through the filter at a programmed rate and a portion is collected in the retained 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. ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer 0.

Certain additives can also have an adverse effect on the rating. 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. Table 1 identifies the recommended test method for various fuels. Each Test Kit contains vacuum packed expendables that are used to perform a single test.

The values given in parentheses are for information only. This event, which takes place in connection with the MEDICA conference and exhibition, brings together medical equipment industry leaders to demonstrate new technology and solutions.

Water Separation Characteristic Test Method D, D and D employs the use of a turbidimeter, a mechanical mixer, and a disposable coalescer filter. Like Test Methods D and D, this test method can detect carryover traces of refinery treating residues in fuel as produced.

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. D948 1 identifies the recommended test method for various fuels. We recently welcomed “Bob” to our engineering team. Test Method D, D and D employs the use of a turbidimeter, a mechanical mixer, and a disposable coalescer filter.
