Maeon laboratories has facility for determining Dielectric properties of insulating materials plastic composites and elastomer compounds used commercially for insulation purposes. This test is useful xstm investigative, reconstructions and quality control purposes. Durometer scale is a type of measurement for rubber and plastic material hardness.
Thermogravimetric Analysis – ACE Products & Consulting
Standards Subsctiption may be the perfect solution. Determination of hardness can be done for substances classified as vulcanized thermoset rubber, thermoplastic elastomers, cellular materials, elastomeric materials, gel-like materials, and plastics. This standard is not included in any packages. Maeon laboratories has test facilities to induce property changes in polymeric materials, which are associated with end-use conditions, such as sunlight, moisture and heat.
If the document is revised or amended, you will be notified by email. Subscription pricing is determined by: The infrared spectrum of the test specimen is superimposed on a reference spectrum and compared for determination of polymer used.
Your Alert Profile lists the documents that will be monitored. Generally flexible plastic materials fall under the Scale Shore A.
Extend of deterioration in properties can be estimated after immersion in the specified chemicals. Tensile properties of Plastics provide very useful information for its engineering design purpose.
Tear resistance which is the ultimate resistance to rupture is estimated. Sheets, extrusions, coatings, hoses and cellular materials can be tested for this parameter. The test helps to determine the uniformity of the flow rate of polymer at a particular condition. Please first log in with a verified email before subscribing to alerts.
A measure of impact resistance of material is useful for Quality estimation purposes. Rate of burning of plastics, and also rate and extent of burning characterises are studied for understanding processing character and deterioration.
Thermogravimetric Analysis (TGA)
The Charpy Impact test indicates the energy of break standard test specimen under Standard conditions with notching. Need more than one copy? No other units of measurement are included in this standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The force to initiate tear for flexible plastic films and sheetings is determined. As the voice of the U.
A test device determines the brittleness point of plastics r under impact at low temperature. Evaluation of Plastic products functioning under chemical contact for mechanical property changes is important for such products.
This test is of prime importance for the Identification of material.

Determination of Flexural properties are important for specifying grades and the control of quality. Proceed to Checkout Continue Shopping. A measure of the Vicat softening temperature of plastics is useful for the characterization of plastics by its heat-softening qualities. The polymers in a given material or product can be determined by Infrared spectrophotometry. It is also used to indicate us astmm physical changes if any, loss of plasticisers, absorption of solvent or because of any other cause.
You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Films of any thickness below 1. Hard plastics use Shore D. Please first verify your email before subscribing to alerts. Add to Alert PDF. Standards Subscriptions from ANSI provides a money-saving, multi-user solution xstm accessing standards. Flexural Strength, Modulus, Flexural strain.
The deterioration caused is evaluated for its end use.
Standard Test Method for Rubber-Compositional Analysis by Thermogravimetry (TGA)
A small mass of test sample is subjected to controlled heating under specific environment and the mass loss over a temperature range is measured. Maeon laboratories has facility for evaluating plastics for its behaviour at low temperature.
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 may delete a document from your Alert Profile at any time. The test method covers a procedure to determine the temperature at which plastics deform when it is subjected high temperature and load.
Already Subscribed to this document. 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 test is intended to measure the ability of rubber to retain elastic properties after prolonged. This standard is also aztm to be included in Standards Subscriptions. Generally Type R indenter is used for Plastics hardness measurements. Characteristics such as Tensile strength, Elongation, Elongation at Yield, Modulus of elasticity and other tensile properties can be determined.
Plastics show significantly different Absorption energy when subjected to an impact load.
