Grease and petrolatum The consistency of grease from almost fluid to semi-fluid to hard can be measured in ast range up to Penetration Units. The penetration test provides information on the texture. In case of central lubrication systems, the penetration is used for the observation of the pumpability of fluid grease. However, if a substance is too liquid it may run off the bread slice. Oxidation Bomb for Petroleum Testing.

ASTM D937 – 07(2012)

A simple method to determine the consistency of different products is by means of a penetrometer. 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.

It describes the appearance, feel, or consistency of a surface or the food itself mouthfeel. Consistency determination of pharmaceutical products and cosmeticssuch as ointment and creams, but also semi-liquid and semi-solid materials, is performed using methods of to the European Pharmacopoeia 2.

It is supplied with 50 and gram weights and standard Typical semi-fluid and semi-solid samples are butter, grease, ointment, and petrolatum.

Grease penetration measurement [1]. The penetration value ensures the adequate feeding of the friction area; the long-term performance of mechanical elements depends heavily on the selection of the right grease according to the penetration class. Penetrometer with hollow cone. A high difference of the values stands for low shear stability, which indicates a poor performance of the grease in practice.

A asfm or solid material needs a certain mechanical stress at which it begins to deform elastically or plastically. Pharmacy and cosmetics Fig. The behavior of the bitumen in the medium temperature range can be assessed by means of the penetration test. Typical negative consequences of neglecting the consistency are:. The NLGI system see point 4.

Consistency gives food the typical mouthfeel that is experienced when it is swallowed.

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

The penetration test is used for adjusting the right asfm. The deeper the cone sinks into the material, the softer the sample and the lower the consistency. Hard bitumen consistency under cold climatic conditions generates fatigue cracks on the road surface and in cold coatings; the material becomes more brittle. This article presents the basic principles of consistency determination with a penetrometer.

Density Redefined Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: Typical applications for penetration testing Bitumen The consistency of semi-solid and solid bituminous materials is tested up to Penetration Units PU. 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.

Sturdy cast iron base r937 excellent support and has a built-in spirit level and leveling screws to insure proper alignment of the penetrometer during testing.

A good spreadability of butter, margarine, cheese, honey, and other food must be ensured. A typical device which is used for the determination of consistency is a penetrometer.

ASTM D – 07() Standard Test Method for Cone Penetration of Petrolatum

Koehler K Penetrometer Condition: Examples which illustrate the importance of consistency measurement are given in section 4. If the consistency of grease becomes too low because of the shear aztm 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.

A penetrometer is very versatile and a lot of different penetration bodies can be used with this instrument, depending on the consistency of the ashm.
