ASTM D937 – 07(2012)

According to the European Pharmacopoeia Method 2. The value is obtained by calculation from needle penetration and the ring-and-ball softening point using a softening point tester. High penetration values indicate softer materials.

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 It is supplied with 50 and gram weights and standard The harder more solid the material, the smaller the cone angle should be. In case of central lubrication systems, the penetration is used for the observation of the pumpability of fluid grease. Pharmacy and cosmetics Fig.

Therefore, a needle is used for bitumen and a perforated disk penetrator is used for liquid-like samples. Lab Equipment for Sale: By using our ashm you consent to all cookies in accordance with our Cookie Policy. Release the load for five seconds and read the penetration distance.

Depending on their physical behavior, all materials can be placed on a scale from highly viscous to semi-solid and solid.

Email Us or call toll-free: This test satm is applicable to waxes having a penetration of not greater than Grease penetration measurement [1]. Head assembly adjusts for accurate placement of the tip of the needle or cone on the surface of the sample.

Samples in a row from fluid left to solid right. A penetration of would represent solid grease, while a penetration of would mean that the sample is fluid.

If the consistency of grease becomes qstm 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. The result is the depth, in tenths of a millimeter Penetration Unit, PUat which the cone sinks into the grease and this expresses the consistency.

The treatment in a grease worker exposes the sample to high mechanical stress in a comparatively short time. Conclusions concerning the following can be drawn from the penetration value: 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.

Enter product namemake or model. This can be solvent molecules, more complex polymeric structures, small particles, gas bubbles, etc. The inner structure is characteristic for each material and can be influenced by outside forces as well as the ambient conditions. Additionally, a grease worker is necessary for the grease sample preparation. Consistency measurement with a penetrometer How does a penetrometer work?

Covers measuring with a penetrometer the penetration of petrolatum as an empirical measure of consistency. Covers determination of the changes in the consistency, as measurably cone penetration, of f937 greases when worked in the roll stability test apparatus. ASTM D, IP 9d37, DIN – 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.

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 products, cosmetics, pastes and other solid to semisolid products.

Grease and petrolatum The consistency of grease from almost atsm to semi-fluid to hard can be measured in a range up to Penetration Units. The NLGI system see point 4. A semi-fluid or solid material needs a certain mechanical stress at which it begins to deform elastically or plastically. Using this value, conclusions can be drawn about the performance of bitumen as a binder for road construction.

The general rule for test kit selection is: Astk point of plastic deformation is called the yield point. Consistency measurement is used r937 determine the degree to which a material resists deformation by an applied force.

Honey, hand cream, toothpaste, sweet jelly, grease bitumen and candle wax: It describes the appearance, feel, or consistency of a surface or the food itself mouthfeel.

The penetration test is used for adjusting the right consistency:. Bitumen testing in a water bath.

Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, xstm hardness, V-blenders, Please fill in the form below to get a quote for the Koehler K Penetrometer:.

The ambient condition that influences the consistency most is the temperature.

Compact design facilitates transport for field use. Precision machined and assembled to exacting specifications, and ruggedly constructed to insure long service life in both laboratory and field applications. However, if a substance is too liquid it may run off the bread slice. Cool the container down to ambient temperature
