According to the European Pharmacopoeia Method 2. 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.
Using this value, conclusions can be drawn about the performance of bitumen as a binder for road construction.

Consistency measurement with a penetrometer How does a penetrometer work? This article presents the basic principles of consistency determination with a penetrometer. Covers measuring with a penetrometer the penetration of petrolatum as an empirical measure of consistency. Consistency describes the degree to asstm a semi-fluid or semi-solid material resists deformation by an applied force.
Therefore, a needle is used for bitumen and a perforated disk penetrator is used for liquid-like samples. Release the load for five seconds and read the penetration distance. Lab Equipment for Sale: The penetration test provides information on the texture. A semi-fluid or solid material needs a certain mechanical stress at which it begins to deform wstm or plastically. Penetration is the basic value for the bitumen classification systems worldwide.
Petroleum Products and Biofuel lab apparatus baths, calorimeters, color measurement, density meters, flash point, hydrogenators, oil testing, penetrometers, surface tension, vapor pressure, viscometers and rheometers, However, if a substance is too liquid it may run off the bread slice.
Type text as it appears:: Covers the empirical estimation of the consistency of waxes derived from petroleum by measurement of the extent of penetration of a standard needle. Examples which illustrate the importance of consistency measurement are given in section 4.
Email Us or call toll-free: Conclusions concerning the following can be drawn from the penetration value:. The general rule for test kit selection is: A good spreadability of butter, margarine, cheese, honey, and other food must be ensured. Product Description This Koehler K penetrometer is designed for ASTM penetration tests on aastm products and for consistency tests on a wide range of food products, cosmetics, pastes and other solid to semisolid products.
Enter product namemake or model. A brief presentation of the globally used ASTM test is given below: Samples in a row from fluid left to solid right.
Seta Half-Scale Penetrometer Cone
A fluid liquid has no such yield point. If the consistency of ketchup is not optimal, it will not flow out of the bottle easily.
The consistency of semi-solid and solid bituminous materials is tested up to Penetration Units PU. A typical device which is used for the determination of consistency is a penetrometer. The ambient condition that influences the consistency most is the temperature. The sensory expectations of the customer have to be fulfilled. General Use laboratory apparatus balances, baths, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification Anything that is dissolved or dispersed in a material contributes to its inner structure.
Conclusion Consistency measurement with a penetrometer provides information about the texture of semi-solid materials with little effort.
Koehler K Penetrometer Condition: Conclusions concerning the following can be drawn s937 the penetration value: Substances we encounter, within the fluid or solid state of matter, can be described according to their consistency, see Figure 1.
Compact design facilitates transport for field use. Penetrometer with hollow cone. The NLGI system see point 4. The simple rheology concept of the device, short measurement asfm, and very good repeatability of the results open up a wide application field. Bitumen testing in a water bath.
The point of plastic deformation is called the yield point. Cover four procedures for measuring the consistency of lubricating greases by the penetration of a cone of specified dimensions, mass and finish.
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.
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 asgm binder.
The treatment in a grease worker exposes v937 sample to high mechanical stress in a comparatively short time. The behavior of the bitumen in the medium temperature range can be assessed by means of the penetration test. Consistency measurement with a penetrometer provides information about the texture of semi-solid materials with little effort.
Head assembly adjusts for accurate placement of the tip of the needle or cone on the surface of the sample. Due to its easy handling, the penetration method is employed in a wide scope of applications for food.
