We recently welcomed “Bob” to our engineering team. Each Test Kit contains vacuum packed expendables that are used to perform a single test. No comments were found for ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer. For quality control purposes, water separation characteristics of fuels are rated to determine the amount of surface active materials surfactants present.

The vial is replaced in the turbidimeter and the water separation characteristic of the fuel is rated.

*ASTM D Emcee Electronics

The value obtained is compared to the unprocessed sample that was used to set the d39488 to Higher ratings, is maximum, indicate that there is less free water and particulate present. Table 1 identifies the recommended test method for various fuels.

He does consume a lot of strange material plastics, metalized thread, rubber, etc. Give Us A Call! It is the responsibility of the user of this standard to establish appropriate safety and health practices e3948 determine the applicability of regulatory limitations prior to use. Test Method D passes a portion of the sample through a filter medium, which is collected in a clear glass, vial.

Test Method D, D and D employs the use of a turbidimeter, a mechanical mixer, and a disposable coalescer filter. Test method selection is dependent on the particular fuel to be tested. 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.

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 processed fuel is discarded and a portion of the unprocessed fuel is placed in the vial, which is re-inserted in the r3948. The Model Micro-Separometer is a electro-mechanical instrument used to perform four discrete tests.

The production hall for pre-treatment, powder coating and new water treatment.

The company specialises d39948 the powder coating of steel, hot-dip galvanised steel and aluminium components. This test method provides a measure of the presence of surfactants in aviation turbine fuels. ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer 0.

These ratings are approximately the same as those obtained using Test Method D The Micro-Separometer has a measurement range from 50 to The values given in parentheses are for information only. A container of distilled water is also included in each Six Pack to perform water separation tests. The primary difference between the modes of operation is the rate of fuel flow through the fiberglass coalescing material. Some of these substances affect the ability of filter separators to separate free water from the fuel.

The values given in parentheses after SI units are provided for information only and are not considered standard. Surfactants degrade the performance of filter separators used to remove water from the fuel. The sample in the vial is discarded and the vial is retained.

The emulsion is passed through the filter at a programmed rate and a portion is collected in the retained vial.

PORTABLE MICROSEPAROMETER ASTM D

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

The higher the rating, being the maximum, the less surfactant present. Table 1 identifies the recommended test method for various fuels. Historical Version s – view previous versions of standard.

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.

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 Get Updates From Emcee delivered to your inbox.

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