Please first verify your email before subscribing to alerts. Determination of hardness can be done for substances classified as vulcanized thermoset rubber, thermoplastic elastomers, cellular materials, elastomeric materials, gel-like materials, and plastics.
A small mass of test sample is subjected to wstm heating under specific environment and the mass loss over a temperature range is measured. Rate s6370 burning of plastics, and also rate and extent of burning characterises are studied for understanding processing character and deterioration.
As the voice of the U. Proceed to Checkout Continue Shopping. Determination of Flexural properties are important for specifying grades and the control of quality. Maeon laboratories has test facilities to induce property changes in polymeric materials, which d63370 associated with end-use conditions, such as sunlight, moisture and heat.
ASTM D6370 – 99(2014)
The deterioration caused is evaluated for its end use. Generally flexible plastic materials fall under the Scale Shore A. Hard plastics use Shore D. Determination of this Ball indentation hardness is generally used for harder plastics, It measures the resistance of plastics towards indentation and provides necessary hardness values. The Charpy Impact test indicates the energy of break standard test specimen under Standard conditions with notching.

Add to Alert PDF. It is also used to indicate us the physical changes if any, loss of plasticisers, absorption of solvent or because of any other cause. The test method covers a procedure to determine the temperature at which plastics deform when it is subjected high temperature and load.
The polymers in a given material or product can be determined by Infrared spectrophotometry. Maeon laboratories offer testing of plastics for the determination of Transition temperatures, such as Entahalpies of Fusion and Crystallization of Polymers — including Tm, Tg, Tc.
You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Characteristics such as Tensile strength, Elongation, Elongation at Yield, Modulus of elasticity and other tensile properties can be determined. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Your Alert Profile lists the documents that will d63770 monitored.
Thermogravimetric Analysis (TGA)
Films of any thickness below 1. This test is useful for investigative, reconstructions and quality ast, purposes. Standards Subsctiption may be the perfect solution. This standard is also available to be included in Standards Subscriptions.
The test helps to determine the uniformity of the flow rate of polymer at a particular condition. Maeon laboratories has facility for evaluating plastics for its behaviour at low temperature.
Evaluation of Plastic products functioning under chemical contact for mechanical property changes is important for such products. Please first log in with a verified email before subscribing to alerts. This test is of prime importance for the Identification of material.
Generally Type R indenter is used for Plastics hardness measurements. Asrm measure of the Vicat softening temperature of plastics is useful for the characterization of plastics by its heat-softening qualities.
Need more than one copy? Extend of deterioration in properties can be estimated after immersion in the specified chemicals. If the document is revised or amended, you will be notified by email.
The test is intended to measure the ability of rubber to retain elastic properties after prolonged.
