Extend of deterioration in properties can be estimated after immersion in the specified chemicals. A measure of impact resistance of material is useful for Quality estimation purposes.
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 of prime importance for the Identification of material. Please first verify your email before subscribing to alerts. 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.
Evaluation of Plastic products functioning under chemical contact for axtm property changes is important for such products. Need more than one copy? Characteristics such as Tensile astn, Elongation, Elongation at Yield, Modulus aastm elasticity and other tensile properties can be determined. A test device determines the brittleness point of plastics r under impact at low temperature. A rectangular test specimen is placed on 2 supports and loaded at the centre of supports.
The deterioration caused is evaluated for its end use. This standard is not included in any packages. We have no amendments or corrections for this standard. Add to Alert PDF. As the voice of the U. If the document is revised or amended, you will be notified by email. No other units of measurement are included in this standard.
Plastic Testing Labs in Chennai | Top Plastic Material Testing Laboratory
Rate of burning of plastics, and also rate and extent of burning characterises are studied for understanding processing character and deterioration. The polymers in a given material or product astj be determined by Infrared spectrophotometry. Maeon laboratories has facility for evaluating plastics for its behaviour at low temperature.
Maeon laboratories has facility for determining Dielectric properties of insulating materials plastic composites and elastomer compounds used commercially for insulation purposes.
Films of any thickness below 1. The test is intended to measure the ability of rubber to retain elastic properties after prolonged.
Standard Test Method for Rubber-Compositional Analysis by Thermogravimetry (TGA)
Tear resistance which is the ultimate resistance to rupture is estimated. Maeon laboratories has aatm facilities to induce property changes in polymeric materials, which are associated with end-use conditions, such as sunlight, moisture and heat. Proceed to Checkout Continue Shopping. The Charpy Impact test indicates the energy of break standard test specimen under Standard conditions with notching.

You may delete a document from your Alert Profile at any time. Generally flexible plastic materials fall under the Scale Shore A. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
This test is useful for investigative, reconstructions and quality control purposes. Subscription pricing is determined by: Determination of Flexural properties are important for specifying grades and the control of quality. Durometer scale is a type of measurement for rubber and plastic material hardness. Your Alert Profile lists the documents that will be monitored. A small mass of test sample is subjected to controlled heating under specific environment and the mass loss over a temperature range is measured.
A measure of the Vicat softening temperature of plastics is useful for the characterization of plastics by its heat-softening qualities. 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. Generally Type R indenter is used for Plastics hardness measurements.
ASTM D6370 – 99(2014)
Determination of hardness can be done for substances classified as vulcanized thermoset rubber, thermoplastic elastomers, cellular materials, elastomeric materials, gel-like materials, and plastics. The test method covers a procedure to determine the temperature at which plastics adtm when it is subjected high temperature and load. The force to initiate tear for flexible plastic films and sheetings is determined. Sheets, extrusions, coatings, hoses and cellular materials can be tested for this parameter.
This standard is also available to be included in Standards Subscriptions.
