Looking for a specific close-up? A fluid liquid has no such yield point. Koehler K Penetrometer Condition: 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.
Waxes differ in consistency. 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. 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.
Conclusion Consistency measurement e937 a penetrometer provides information about the texture of semi-solid materials with little effort.
The penetration test provides information on the texture.
Seta Half-Scale Cone, ASTM D, ASTM D, ASTM D
Prior to asym yield wstm the material will deform elastically and will return to its original shape when the applied mechanical stress is removed. Test cones, needles and lightweight plunger where applicable are available to be ordered separately. 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 astn machine. This helps when selecting the bitumen binder best suited to the climatic conditions of the respective region.
Place the water-covered container water level at least 25 mm above the sample container surface on asm penetrometer table. Difference between fluid, semi-solid, and solid materials Fig. A penetrometer is very versatile and a lot of different penetration bodies can be used with this instrument, depending on the consistency of the sample. It is supplied with 50 and gram weights and standard The treatment in a grease worker exposes the sample to high mechanical stress in a comparatively short time.
A semi-fluid or solid material needs a certain mechanical stress at which it begins to deform elastically or plastically.
ASTM D – 07() Standard Test Method for Cone Penetration of Petrolatum
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. Covers determination of the changes in the consistency, as measurably cone penetration, of lubricating greases when worked in the roll stability test apparatus. If the consistency of ketchup is not optimal, it will not flow out of the bottle easily.
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. Consistency measurement with a penetrometer How does a penetrometer work? Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, Covers measuring with a penetrometer the penetration of petrolatum as an empirical measure of consistency.
The NLGI system atm point 4.
The general rule for test kit selection is: Hard bitumen consistency under cold climatic conditions generates fatigue cracks ast the road surface and in cold coatings; the material becomes more brittle. The penetration test is used for adjusting the right consistency: The simple rheology concept of the device, short measurement time, and very good repeatability of the results open up a wide application field. A typical device which is used for the determination of consistency is a penetrometer.
Consistency gives food the typical mouthfeel that is experienced when it is swallowed. The sensory expectations of the customer have to be fulfilled.

Honey, hand cream, toothpaste, sweet jelly, grease bitumen and candle wax: A lot of different penetration test kits v937 used for chemical products such as adhesives, sealants, and glue pastes. Oxidation Bomb for Petroleum Testing. We come across consistency all the time in everyday life asm even thinking about it.

A brief presentation of the globally used ASTM test is given below: The point of plastic deformation is called the yield point. The value is obtained by calculation from needle penetration and the ring-and-ball softening point using a softening point tester. Ast 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.
The inner structure is characteristic for each material and can be influenced by outside forces as well as the ambient conditions.
This article presents the basic principles of consistency determination with a penetrometer. Grease penetration measurement .
A brief presentation of the globally used ASTM test is given below:. What is an inner structure? ASTM D, IPDIN – Needle penetration of asm waxes Covers the empirical estimation of the consistency of waxes derived from 9d37 by measurement of the extent of penetration of a standard needle.
According to the European Pharmacopoeia Method 2. Penetration is the basic value for the bitumen classification systems worldwide.
