The value is obtained by calculation from needle penetration and the ring-and-ball softening point using a softening point tester. The deeper the cone sinks into the material, the softer the sample and the lower the consistency.
This test method is applicable to waxes having a penetration of not greater than A typical device which is used for the determination of consistency is a penetrometer. 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 sensory expectations of the customer have to be fulfilled. Test cones, needles and lightweight plunger where applicable are available to be ordered separately. Once the yield point is passed, a fraction of the deformation will be permanent and nonreversible.
This helps when selecting the bitumen binder best suited to the climatic conditions of the respective region. By using our website you consent to all cookies in accordance with our E937 Policy. Cool the container down to ambient temperature 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.
Especially for the evaluation of processes such as kneading, pumping, mixing, filling, and brushing, it is essential to optimize the energy balance by adjusting the consistency. A fluid liquid has no such yield point. Release the load v937 five seconds and read the penetration distance. The NLGI system see point 4. Available request a quote. The harder more solid the material, the smaller the cone angle should be.
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 asttm run dry; friction and wear will increase on the contact area.
Conclusions concerning the following can be drawn from the penetration value: Consistency measurement with a penetrometer How does a penetrometer work? A simple method to determine the consistency of different products is by means of a penetrometer.
Conclusions concerning the following can be drawn from the penetration value:. Adjust the tip of the needle so that it is just touching the sample d973. Consistency describes the degree to which d97 semi-fluid or semi-solid material resists deformation by an applied force.
Samples in a row from fluid left to solid right. Record the average of four penetrations on the sample in the container as a single test result. 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.
ASTM D, AsmtDIN – Needle penetration of petroleum waxes Covers the empirical estimation of the consistency of waxes derived from petroleum by measurement aatm the extent of penetration of a standard needle.
Conclusion Consistency measurement with a penetrometer provides information about the texture of semi-solid materials with little effort. Prior to the yield point the material will deform elastically and will return to its original shape when the applied mechanical stress is removed. The general rule for test kit selection is: The consistency of semi-solid and solid bituminous materials is tested up to Penetration Units PU. Place the water-covered container water level at least 25 mm above the sample container surface on the penetrometer table.
ASTM D – 07() – Standard Test Method for Cone Penetration of Petrolatum
It describes the appearance, feel, or consistency of a surface or the food itself mouthfeel. The ambient condition that influences the consistency most is the temperature. 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. Pharmaceutical laboratory apparatus stability chambers, d9337 disintegration, tablet dissolution, tablet hardness, V-blenders, Astn lot of different penetration test kits are used for chemical products such as adhesives, sealants, and glue pastes.
This instrument features a full penetration range of Covers determination of the changes in the consistency, as measurably cone penetration, of lubricating greases when worked in asym roll stability test apparatus. Covers the empirical estimation of the consistency of waxes derived from petroleum by measurement of the extent of penetration of a standard needle.
Lin-Tech: Penetration of Bituminous Material, Grease, Petrolatum, Waxes, Gel
A good spreadability of butter, margarine, cheese, honey, and other food must be ensured. The inner structure is characteristic for each material and can be influenced by outside forces as well as the ambient conditions. Further materials A lot of different penetration test kits are used for chemical products such as adhesives, sealants, and glue pastes.
A typical example of consistency determination is the penetration measurement of grease. What type of cone or needle? According to the European Pharmacopoeia Method 2. This can be solvent molecules, more complex polymeric structures, small particles, gas bubbles, etc.
