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. A rectangular test specimen is placed on 2 supports and loaded at the centre of supports.
If the document is revised or amended, you will be notified by email. Evaluation of Plastic products functioning under chemical contact for mechanical property changes is important for such products. The deterioration caused is evaluated for its end use.
Thermogravimetric Analysis – ACE Products & Consulting
Hard plastics use Shore D. The test is intended to measure the ability of rubber to d63770 elastic properties after prolonged. Flexural Strength, Modulus, Flexural strain. Tear resistance which is the ultimate resistance to rupture is estimated. It is also used to indicate us the physical changes if any, loss of plasticisers, absorption of solvent or because of any other cause.
This test is useful for investigative, reconstructions and quality control purposes. Characteristics such as Tensile asstm, Elongation, Elongation at Yield, Modulus of elasticity and other tensile asym can be determined. Maeon laboratories has facility for determining Dielectric properties of insulating materials plastic composites and elastomer compounds used commercially for insulation purposes.
Maeon laboratories has facility for evaluating plastics for its behaviour at low temperature. Films of any thickness below 1. 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.
Standards Subsctiption may be the perfect solution. A measure of impact resistance of material is useful for Quality estimation d637. Sheets, extrusions, coatings, hoses and cellular materials can be tested for this parameter.
Thermogravimetric Analysis (TGA)
As the voice of the U. A measure of the Vicat softening temperature of plastics is useful for the characterization of plastics by its heat-softening qualities. Tensile properties of Plastics provide very useful information for its engineering design purpose.
Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Generally flexible plastic materials fall under the Scale Shore A. Plastics show significantly different Absorption energy when subjected to an impact load. Durometer scale is a type of measurement for rubber and plastic material hardness. Extend of deterioration in properties can be estimated after immersion in the specified chemicals.
Proceed to Checkout Continue Shopping. The force to initiate tear for flexible plastic films and sheetings is determined. Determination of Flexural properties are important for specifying grades and zstm control of quality.
Please first log in with a verified email before subscribing to alerts. This standard is not included in any packages. Generally Type R indenter is used for Plastics hardness measurements. No other units of measurement are included in this standard.
The Charpy Impact test indicates the energy of break aztm test specimen under Standard asgm with notching. Need more than one copy?
The infrared spectrum of adtm test specimen is superimposed on a reference spectrum and compared for determination of polymer used.
The test method covers a procedure to determine the temperature at which plastics deform when it is subjected high temperature and load. Your Alert Profile lists the documents that will be monitored. 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. We have no amendments or corrections for this standard.
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 also available to be included in Standards Subscriptions. Add to Alert PDF. Please first verify your email before subscribing to alerts.
A small mass of test sample is subjected to controlled heating under specific environment and the mass loss over a temperature range is measured.
The test helps to determine the uniformity of the flow rate of polymer at a particular condition. 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.
