Also covered are procedures for conditioning test coupons prior to use in other test methods; either to an essentially moisture-free state, to equilibrium in a standard laboratory atmosphere environment, or to equilibrium in a non-laboratory environment. This procedure is repeated until there is no discernable increase in specimen weight. The specimens are then weighed on an analytical balance to the nearest 0.

Asstm how your products and services meet and exceed quality, safety, sustainability and performance standards. Formally confirming that your products and astm d meet all trusted external and internal standards. Properties determined in the latter manner shall be reported aastm apparent properties. The validity of the equations used in Procedure A for evaluating the moisture diffusivity constant in a material of previously unknown moisture absorption behavior is uncertain prior to the test, as the test results themselves determine if the material follows the single-phase Fickian diffusion model.

The validity of the equations used in Procedure A for evaluating the moisture diffusivity constant in a material of previously unknown moisture absorption behavior is uncertain prior to the test, as the test results themselves determine if the material follows the single-phase Fickian diffusion model.

Also included are procedures for determining the moisture loss during elevated temperature testing, as d2529 as moisture loss resulting from thermal exposure after removal from the conditioning environment, such as during strain gage bonding.

ASTM D testing provides a variety of procedures in order to determine the moisture absorption or disorption properties. Other examples of materials and test conditions that may not meet the requirements are discussed in Section 6.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Aztm is a gravimetric test that monitors the change in moisture content over astm d Within ASTM D there are three other procedures covering material conditioning within a specific moisture environment.

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.

Need help or have a question? The side edges are then sealed to prevent moisture absorption through the sides.

Combining values from the two systems may result in nonconformance with the standard. Inspection Validating the specifications, value and safety of your raw materials, products and assets. While the astm d procedures themselves may be used for multi-phase materials, astm d calculations used to determine the moisture diffusivity constant in Procedure A are applicable only to astm d materials.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This procedure will result in the diffusivity constant, Dz and the moisture equilibrium content, Mm at the given moisture exposure level and temperature.

Properties determined in the latter manner shall astm d reported as apparent properties.

Moisture Absorption of Matrix Composites by ASTM D

ASTM D testing provides a variety of procedures in order to determine the moisture absorption or disorption properties. There are several procedures that are discussed throughout this method. The side edges are then sealed to prevent moisture absorption through the sides.

While the test procedures themselves may be used for multi-phase materials, the calculations used to determine the moisture diffusivity constant in Procedure A are applicable only to single-phase materials. This procedure will result in the diffusivity constant, Dz and the moisture equilibrium content, Mm at the given moisture exposure level and temperature.

A reinforced polymer matrix composite material tested below its glass-transition temperature ast, meets this requirement, although two-phase matrices such as toughened epoxies may require a multi-phase moisture absorption model. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

Within ASTM Astm d there are three other procedures covering material conditioning astm d a specific moisture environment.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Other examples of materials and test conditions that may not meet the requirements are discussed in Section 6. Validating the specifications, value and safety of your raw materials, products and assets.
