Pharmacy and cosmetics Fig. This can be solvent molecules, more complex polymeric structures, small particles, gas bubbles, etc. Especially for the evaluation of processes such as kneading, pumping, mixing, filling, and brushing, it is essential to optimize the energy balance by adjusting the consistency. Consistency gives ast the typical mouthfeel that is experienced when it is swallowed.
Dd937 harder more solid the material, the smaller the cone angle should be. Consistency measurement with a penetrometer provides information about the texture of semi-solid materials with little effort.
ASTM D – 07() Standard Test Method for Cone Penetration of Petrolatum
Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: Waxes differ in consistency. Head assembly adjusts for accurate placement of the tip of the needle or cone on the surface of the sample. Looking for a specific close-up?
The behavior of the bitumen in the medium temperature range can be assessed by means of the penetration test. The treatment in a grease worker exposes the sample to high mechanical stress in a comparatively short time.
The penetration is measured before and after applying many double strokes up to 1, of a perforated plate in the greased-filled cup placed in the working machine. A brief presentation of the globally used ASTM test is given below: Therefore, a needle is used for bitumen and a perforated disk penetrator is used for liquid-like samples. The point of plastic deformation is asstm the yield point.

Cool the container down to ambient temperature The NLGI system see point 4. Typical semi-fluid and semi-solid samples are butter, grease, ointment, and petrolatum.
Koehler K19500 Penetrometer
Precision machined and assembled to exacting specifications, and ruggedly constructed to insure long service life in both laboratory and field applications. If the consistency of grease becomes too low because of the shear stress in the mechanical aggregateit may leak away from the area to be lubricated and parts will run dry; friction and wear will increase on the contact area.
This article presents the basic principles of consistency determination with a penetrometer. Oxidation Bomb for Petroleum Testing. Email Us or call toll-free: Typical negative consequences of neglecting the consistency are:.
ASTM D – 97 Standard Test Method for Cone Penetration of Petrolatum
Koehler K Penetrometer Condition: Additionally, a grease worker is necessary for the grease sample preparation. What type of cone or needle?
Typical applications for d973 testing Bitumen The consistency of semi-solid and solid bituminous materials is tested up to Penetration Units PU. A simple method to determine the consistency of different products is by means of a penetrometer.
A penetration of astj represent solid grease, while a penetration of would mean that the sample is fluid. However, if a substance is too liquid it may run off the bread slice. ASTM D – Roll stability of lubricating grease Covers determination of the changes in the consistency, as measurably cone penetration, of lubricating greases when worked in the roll stability test apparatus.
Sturdy cast iron base provides excellent support and has a built-in spirit level and leveling screws to insure proper alignment of the penetrometer during testing. This helps when selecting the bitumen binder best suited to the climatic conditions of the respective region.
