Moisture Content by Karl Fischer ASTM D
Flow behavior is an indirect measure of product consistency and quality where materials must be consistent from batch to batch.

Auditing Consulting Sourcing Training. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Assurance Enabling you to identify and asm the intrinsic risk in your operations, supply chains and business processes. The Brookfield Viscometer determines viscosity by measuring the force to turn the spindle in the solution at a given rate. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. Moisture Content by Karl Fischer. The water in the sample is vaporized and carried by dry oxygen free nitrogen into a reaction vessel with methanol.

Moisture Content by Karl Fischer
One to three grams. Knowledge of the moisture content can be important since some polymers degrade when molded wet resulting in reduced properties.
Also, hygroscopic materials like nylon absorb moisture and knowledge of the water content can d78 important in understanding performance. The time and temperature values are arrived at by testing a similar material and varying the temperature and bake time independently to determine optimal conditions for removal of all water in the sample.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Karl Fischer is used to determine the water content of samples. A temperature value too high can degrade the polymer and actually generate water in some cases.
Relative Viscosity of Polyamide (Brookfield Method) ASTM D789, D4878
Viscosity is the property of resistance to flow exhibited within the body of a material at a given shear rate. Water content in percent or parts per million is determined. The prepared solution is placed in the Brookfield Viscometer and a proper speed is selected for the spindle according to the expected viscosity of asm sample.
A small weighed sample is placed into the Karl Fischer drying oven at a predetermined temperature for astj predetermined period of time.
Formic acid is added to an eight ounce screw cap bottle asm with Standards can be obtained from appropriate standards authorities. To request a quote for this test or others Click Here.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Due to copyright restrictions, dd789 are not able to provide copies of standards.
Also, molded parts can d798 compared to original resin to determine the extent of degradation from the molding process since degraded material would be lower in viscosity as a result of reduced molecular weight.
It can be more accurate than simple weight loss because in the weight loss method volatiles other than water can be lost which is translated into an artificially high water content.
Certification Formally confirming that your products and services meet all trusted external and internal standards. The methanol aztm the water which is titrated to an end point with a Karl Fischer reagent to determine the amount present. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
