The penetration test is used for adjusting the right consistency: Adtm inner structure is characteristic for each material and can be influenced by outside forces as well as the ambient conditions. Cover four procedures for measuring the consistency of lubricating greases by the asym of a cone of specified dimensions, mass and finish. Typical negative consequences of neglecting the consistency are: Grease and petrolatum The consistency of grease from almost fluid to semi-fluid to hard can be measured in a range up to Penetration Units.

This instrument features a full penetration range of The simple rheology concept of the device, short measurement time, and very good repeatability of the results open up a wide application field. The consistency of semi-solid and solid bituminous materials is tested up to Penetration F937 PU. This article presents the basic principles of consistency determination with a penetrometer.

Koehler K19500 Penetrometer

Record the average of four penetrations on the sample in the container as a single test result. Due to its easy handling, the penetration method is employed in a wide scope of applications for food. Covers determination of the changes in the consistency, as measurably cone penetration, of lubricating greases when worked in the roll stability test apparatus.

Hard bitumen consistency under cold climatic conditions generates fatigue cracks on the road surface and in cold coatings; the material becomes more brittle. Once the yield point is passed, a fraction of the deformation will be permanent and nonreversible. Grease penetration measurement [1]. Using satm value, conclusions can be drawn about the performance of bitumen as a binder for road construction. If the consistency of ketchup is not optimal, it will not flow out of the bottle easily.

Bitumen testing in a axtm bath. Enter product namemake or model. 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.

Definition of consistency Consistency describes the degree to which a semi-fluid or semi-solid material resists deformation by an applied force. It is supplied with 50 and gram weights and standard Typical negative consequences of neglecting the consistency are:.

What are your requirements. However, if a substance is too liquid it may run off the bread slice.

ASTM D – 97 Standard Test Method for Cone Penetration of Petrolatum

Examples which illustrate the importance of consistency measurement are given in section 4. Place the water-covered container water level at least 25 mm above the sample container surface on the penetrometer table. Product Description This Koehler K penetrometer is designed for ASTM penetration tests on petroleum products and for consistency tests on a wide range of food aastm, cosmetics, pastes wstm other solid to semisolid products.

ASTM D, IPDIN – Needle penetration of petroleum waxes Covers the empirical estimation of the consistency of waxes derived from petroleum by measurement of the extent of penetration of a standard needle. The d37 is the depth, in tenths of a millimeter Penetration Unit, PUat which the cone sinks into the grease and this expresses the consistency.

Right-click to open the PDF in a new window or download it: The penetration is measured before and after applying satm double strokes up to 1, of a perforated plate in the greased-filled cup placed in the working machine. Soft bitumen consistency under warm climatic conditions causes ruts on the road and bitumen to drop off roof shingles because of an insufficient stiffness of the bitumen binder.

Depending on their physical behavior, all materials can be v937 on a scale from highly viscous to semi-solid and solid. If the consistency of grease becomes too low because asttm the shear stress in the mechanical aggregateit may leak away from the area to be lubricated and parts will run dry; asym and wear will increase on the contact area.

This test method is applicable to waxes having a penetration of not greater than Available request a quote. Additionally, a grease worker is necessary for the grease sample preparation. Head assembly adjusts for accurate placement of the tip of the needle or cone on the surface of the sample.

Waxes differ in consistency. Conclusion Consistency measurement with a penetrometer provides information about the texture of semi-solid materials with little effort.
