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

It describes the appearance, feel, or consistency of a surface or the food itself mouthfeel. The penetration value s937 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.

Examples which illustrate the importance of consistency measurement are given in section 4. Consistency measurement with a penetrometer How does a penetrometer work? Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, Typical semi-fluid and semi-solid samples are butter, grease, ointment, and petrolatum.

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 ASTM D – Roll stability of lubricating grease Covers determination of the changes in the consistency, as measurably cone penetration, of lubricating greases when worked in the roll stability test apparatus.

Conclusions concerning the following can be drawn from the penetration value:. This helps when selecting the bitumen binder best suited to the climatic conditions of the respective region.

ASTM D937 – 07(2012)

Depending on their physical behavior, all materials can be placed on a scale from highly viscous to semi-solid and solid. Release the load for five seconds and read the penetration distance. Typical applications for penetration testing Bitumen The consistency of semi-solid and solid bituminous materials is tested up to Penetration Units PU.

ASTM D973, 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.

This test method is applicable to waxes having a penetration of not greater than A brief presentation of the globally used ASTM test is given below: What type of cone or needle?

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

The value is obtained by calculation from needle penetration and the ring-and-ball softening point using a softening point tester. Prior to the yield point the material will deform elastically and will return to its original shape when the applied mechanical stress is removed. Type text as it appears:: Ast, testing in a water bath. 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.

We come across consistency all the time in everyday life without even thinking about it. A fluid liquid has no such yield point.

Anton Paar has once again redefined digital density measurement with the groundbreaking invention of a new measuring principle: High asgm values indicate softer materials. Micro-cone set; cup assembled.

Substances we encounter, within the fluid or solid state of matter, can be described according to their consistency, see Figure 1. Therefore, a needle is used for axtm and a perforated disk penetrator is used for liquid-like samples. 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.

Waxes differ in consistency. Hard grease will not work properly for a bearing that needs to be lubricated as it will not adequately grease the whole contact area. Record the average of four penetrations on the sample in the container as a single test d9337. This website uses cookies to improve user experience.

Honey, hand cream, toothpaste, sweet jelly, grease bitumen and candle wax: A simple method to determine the consistency of different products is by means of a penetrometer.

Typical negative consequences of neglecting the consistency are:. Available request a aatm. Looking for a specific close-up? Consistency gives food the typical mouthfeel that is experienced when it is swallowed.

A lot of different penetration test kits are used for chemical products such as adhesives, sealants, and glue pastes. Place the water-covered container water level at least 25 mm above the sample container surface on the penetrometer table. A typical example of consistency determination is the penetration measurement of grease.
