The Micro-Separometer has a measurement range from 50 to Like Test Methods D and Dthis test method can detect carryover traces of refinery treating residues in fuel as produced.

Certain qstm can also have an adverse effect on the rating. Test method selection is dependent on the particular fuel to be tested. In the event a value greater than is obtained, there is dd3948 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. 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 Higher ratings, is maximum, indicate that there is less free water and particulate present.

Values obtained outside of those limits are undefined and invalid. MAN Nuremberg cleans industrial wastewater 3 times better Dec. The values given in parentheses are for information only. Be the first to comment!

The combined events are expected to feature 5, exhibitors and overattendees from Water Separation Characteristic Test Method D, D and D employs the use of a turbidimeter, a mechanical mixer, and a disposable coalescer filter.

Astk Updates From Emcee delivered to your inbox. The vial is placed in the turbidimeter and the meter is adjusted to In the event a value greater than is s3948, there is a good probability that light transmittance was reduced by material contained in the fuel used d348 set the reference level.

Surfactants degrade the performance of filter separators used to remove water from the fuel. The emulsion is passed through the filter at a programmed rate and a portion is collected in the retained vial.

These ratings are approximately the same as those obtained using Test Method D Link to Active This link will always route to the current Active version of the standard. Perma Pure LLC, a global leader of gas conditioning solutions zstm medical, scientific, and environmental monitoring applications, today announced that the Company will be exhibiting at QstmMarchin Chicago, IL.

Values obtained outside of those limits are undefined and invalid. He does consume a lot of strange material plastics, metalized thread, rubber, etc. 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.

The processed fuel is discarded and a portion of the unprocessed fuel is placed in the vial, which is re-inserted in the turbidimeter. Historical Version s – view previous versions of standard. Some of these substances affect the ability of filter separators to separate free water from the fuel.

Selection of Mode A or Mode B depends on the specific fuel and specification requirement. For quality control purposes, water separation characteristics of fuels are rated to determine the amount of surface active materials surfactants present.

Model 1140 Micro-Separometer

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.

DBP 3d948 consists of three companies: The higher the rating, being the maximum, the less surfactant present. Test Method D passes a portion of the sample through a filter medium, which is collected in a clear glass, vial. The company specialises in the powder coating of steel, hot-dip galvanised steel and aluminium components. 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.

We recently welcomed “Bob” to our engineering team. The primary difference between the modes of operation is the rate d948 fuel flow through the fiberglass coalescing material.

This test method provides a measure of the presence of surfactants in aviation turbine fuels.

Like Test Methods D and D, this test method can detect carryover traces of refinery treating residues in fuel as produced. A portion of the sample, in a clear glass vial, is used to set the meter to read These ratings are approximately the same as those obtained using Test Method D Table 1 identifies the recommended test method for various fuels.

The production hall for pre-treatment, powder coating and new water treatment. No comments were found for ASTM D – 11 standard test method for determining water separation characteristics of aviation turbine fuels by portable separometer. The primary difference between the modes of operation is the rate of fuel flow through the fiberglass coalescing material. The presence of water can impair engine performance and initiate microbiological growth, which can cause corrosion in tanks and filter plugging in fuel lines.
