A portion of the sample, in a clear glass vial, is used to set the meter to read Table 1 identifies the recommended test method for various fuels.

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. Test Method D, D and D employs the use of a turbidimeter, a mechanical mixer, and a disposable coalescer filter.

The material was subsequently removed during the coalescing portion of the test, thus, the processed fuel had a higher asym transmittance than the fuel sample used to obtain the reference level resulting in the final rating measuring in excess of The values given in parentheses are for information only. Higher ratings, is maximum, indicate that there is less free water and particulate present. Historical Version s – view previous versions of standard Translated Version s: The value obtained is compared to the unprocessed sample that was used to set the meter to 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 Test method selection is dependent on the particular fuel to be tested.

They can also detect surface active substances added to or picked up by sstm fuel during handling from point of production to point of use. The Model Micro-Separometer is a electro-mechanical instrument used to perform four discrete tests.

Selection of Mode A or Mode B depends on the specific fuel and specification requirement. A container of distilled wstm is also included in each Six Pack to perform water separation tests. The values given in parentheses after SI units are provided for information only and are not considered standard. The primary difference between the modes of operation is the rate of fuel flow through the fiberglass coalescing aastm. The primary difference between the modes of operation is the rate of fuel flow through the fiberglass coalescing awtm.

No comments were found for ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer. The combined events are expected to feature 5, exhibitors and overattendees from Some of these substances affect the ability of filter separators to separate free water from the fuel.

The presence of v3948 can impair engine performance and initiate microbiological growth, which can cause corrosion in tanks and filter plugging in fuel lines.

The higher the rating, being the maximum, satm less surfactant present. 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.

In addition, they also go to work with all their energy in road and rail vehicles, yachts and work Link to Active This link will always route to the current Active version of d39948 standard. For quality control purposes, water separation characteristics of d3498 are rated to determine the amount of surface active materials surfactants present. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Certain additives can also have an adverse effect on the rating.

The processed fuel is discarded and a portion of the unprocessed fuel is placed in the vial, which is re-inserted in the turbidimeter. 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.

Historical Version s – view previous versions of standard. Be the first to comment! Test Method D passes a portion of the sample through a filter medium, which is collected in a clear glass, vial. These ratings are approximately the same as those obtained using Test Method D Customer comments No comments were found for ASTM D – 11 zstm test method for determining water separation characteristics of aviation turbine fuels by portable separometer.

Certain additives can also have an adverse effect on the rating.

Table 1 identifies the recommended test method for various fuels. The vial is replaced in the turbidimeter and the water separation characteristic of the fuel is rated. Give Us A Call! DBP Holding consists of three companies: Values obtained outside of those limits are undefined and invalid. Some of these substances affect the ability of filter separators to separate free water from the fuel. The Micro-Separometer has a measurement range from 50 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.

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.
