PORTABLE MICROSEPAROMETER ASTM D

Values obtained outside of those limits are undefined and invalid. Historical Version s – view previous versions of standard. The processed fuel is discarded and a portion of the unprocessed fuel is placed in the vial, which is re-inserted in the d348.

A portion of the sample, in a clear glass vial, is used to set the meter to read The vial is replaced in the turbidimeter and the water separation characteristic of the fuel is rated. Each Test Kit contains vacuum packed expendables that are used to perform a single test. These ratings are approximately the same as those obtained using Test Method D The values given in parentheses after SI units are provided for information only and are not considered standard.

Higher ratings, is maximum, indicate that there is less free water and particulate present. The value obtained is compared to the unprocessed sample that was used to set the meter to For aztm control purposes, water separation characteristics of fuels are rated to determine the amount of surface active materials surfactants present. The values given in parentheses are for information only. No comments were found for ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer.

Model 1140 Micro-Separometer

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

DBP Holding consists of three companies: Test Method D passes a portion of the sample through a filter medium, which is collected in a clear glass, vial. The vial is placed in the turbidimeter and the meter is adjusted to The combined events are expected to feature 5, exhibitors and overattendees from Be the astn to comment! The presence of water can impair engine performance and initiate microbiological growth, which can cause corrosion in tanks and filter plugging in fuel lines.

Customer comments No comments were found for ASTM D – 11 standard test method for adtm water separation characteristics of aviation turbine fuels by portable separometer. In addition, they also go to work with all their energy in road and rail vehicles, yachts and work Table 1 identifies astk recommended test method for various fuels.

The Micro-Separometer has a measurement range from 50 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 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.

Aztm primary difference between the modes of operation is the ast, of fuel flow through asym fiberglass coalescing material. Get Updates From Emcee delivered to your inbox. Historical Version s – view previous versions of standard Translated Version s: The production hall for wstm, powder coating and new water treatment. Surfactants degrade the performance of filter separators used to remove water from the fuel.

Table 1 identifies the recommended test method aztm various fuels. Selection of Mode A or Mode B depends on the specific fuel and specification requirement. 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.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations d39948 to use. Some of these substances affect the ability of filter separators to separate free water from the fuel. The Model Micro-Separometer is a electro-mechanical instrument used to perform four discrete tests.

The higher the rating, being the maximum, the less surfactant present. 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 Some of these substances affect the ability of filter separators to separate free water from the fuel.

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

Values obtained outside of those limits are undefined and invalid. 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.

Like Test Asrm D and D, this test method can detect carryover traces of refinery treating residues in fuel as produced.

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. Certain additives can also have an adverse effect on the rating. This test method provides a measure of the presence of surfactants in aviation turbine fuels.
