Astn help astm d5229 have a question? Through our network of over 43, people in 1, laboratories and offices astm d5229 countries, Intertek provides quality and safety solutions to a wide range of industries around the world. Multiple tests at differing temperatures are required to establish the dependence of D z on temperature.
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.
Select from list below: Astm d5229 is a gravimetric astm d5229 that monitors the change in moisture content over aetm. Procedure D covers the conditioning of material d229 to an essentially moisture-free condition. Auditing Consulting Asttm Astm d5229.
Procedure B covers general moisture conditioning of material coupons prior to any other material property testing. 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. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.

Link to Active This link will astm d5229 route to the current Active version of the standard. Note 2 — For many polymer matrix composites the moisture absorption properties under atmospheric humid conditions are generally not equivalent to exposure either to liquid immersion or to pressurized steam.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Also included are procedures for determining the moisture loss during astm d5229 temperature testing, as well as moisture loss resulting from thermal exposure after removal from astm d5229 conditioning environment, such as astm d5229 strain gage bonding.
While the test procedures themselves may be used for multi-phase materials, the calculations asym to determine the moisture diffusivity ashm in Procedure A are applicable only to single-phase materials.
ASTM D5229/D5229M – 14
Astm d5229 Testing Inspection Certification. Combining values from the two systems may result astm d5229 nonconformance with the standard. Note 1 — For many polymer matrix composites the moisture diffusivity is usually only weakly related to relative humidity and is often assumed to be a function only of temperature, usually following an Arrhenius-type exponential relation with inverse absolute temperature.
ASTM D testing axtm a variety of procedures in order to determine the moisture absorption or disorption properties. Other examples of materials and test conditions astm d5229 may not meet the requirements are discussed in Section 6. The validity astm d5229 the equations used in Procedure A for evaluating the moisture diffusivity constant in astm d5229 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Historical Version s – view previous versions of astm d5229. The values stated in each system are not sstm equivalents; therefore, each astm d5229 must be used independently of the other. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.
While intended primarily for laminated polymer matrix composite materials, these procedures are also applicable to other materials that satisfy the assumptions of 1. Certification Formally confirming that your products and services meet all trusted external and internal standards. Multiple tests at differing moisture exposure levels are required to establish the dependence of M m on moisture astm d5229 level. D52299 specimens are then placed in the appropriate conditioning environment.
The specimens are then dried, removed from the drying oven, and allowed to cool in a desiccator. For many of these materials, moisture equilibrium content is only weakly related to temperature and is usually assumed to be a function only of relative humidity. Ast included are asgm for determining the moisture loss during elevated temperature testing, as well c5229 moisture loss resulting from thermal exposure after removal astm d5229 the conditioning environment, such as during strain gage bonding.

Moisture Absorption of Matrix Composites by ASTM D
A reinforced polymer matrix composite material tested below its glass-transition temperature typically meets this requirement, although two-phase matrices such as toughened epoxies astm d5229 require a multi-phase moisture absorption model.
