In general, it will not be possible to exclude the effect of these factors completely. The values in parentheses are for information only.
ASTM D Test Method - Analysis Tech
Where testing outside of this temperature range or when linear thermal expansion characteristics of a particular plastic are not known through this temperature range, particular attention shall be paid to the factors mentioned in 1.
The coefficient of linear thermal expansion is calculated between the desired temperature ranges.
Ast our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. The values in parentheses are for information only. Validating the specifications, value and safety of your raw materials, products and assets. Send us a request Wilton UK: For the TMA, the test specimen should be between 2 and 10 mm.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. This test method is intended for determining the coefficient of linear thermal expansion under the exclusion of these factors as far as possible.
Determination and Report of Procedures. For materials having very low coefficient of expansion, interferometer or capacitance techniques are recommended.
Plastics | ASTMD | Prospector
Historical Version s - view previous versions of standard. Once such a transition point has been located, a separate coefficient of expansion for a temperature range below and above the transition point shall be determined.
Standards can be obtained from appropriate standards authorities. For the dilatometer, the test sample should be approximately For materials having very low coefficient of expansion, interferometer or capacitance techniques are recommended.
Active view current version of awtm. Due to copyright restrictions, we are not able to provide copies of standards. The furnace is raised and the temperature is brought to 20 degrees below the lowest temperature of interest.
ASTM D696 Standard
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. 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 height is measured by the probe. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
Coefficient of Linear Thermal Expansion ASTM E831, ASTM D696, ISO 11359
D Practice for Plastics: For this reason, the test method can be expected to give only an approximation to the true thermal expansion.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Alternatively, a dilatometer can be used. At the test temperatures and under the stresses imposed, the plastic materials shall have a negligible creep or elastic strain rate or both, insofar as these properties would significantly affect the accuracy of the measurements. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
Assurance Testing Inspection Certification. Formally confirming that your products and services meet all trusted external and internal standards. Certification Formally confirming that your products and services meet all trusted external and internal e696.
