Send us a request Wilton UK: Formally confirming that your products and services meet all trusted external and internal standards.
Multiple tests at differing astm d5229 are required to establish the dependence of D z on temperature. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Assurance Testing Inspection Certification. A reinforced polymer matrix composite material tested below its glass-transition temperature typically meets this requirement, although two-phase matrices such as toughened epoxies may require a multi-phase moisture absorption model.
The side edges are then sealed to prevent moisture absorption through the sides. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Procedure B covers general moisture conditioning of material coupons prior astm d5229 any other material property testing. Procedure D covers the conditioning astm d5229 material astm d5229 to an essentially moisture-free condition.
This is a gravimetric test that monitors the change in moisture content over time. Within Astm d5229 D there are three other procedures covering material conditioning within a specific moisture environment. There are several procedures that are discussed throughout this method. D529 specimens are then weighed on an analytical balance to the nearest 0. astm d5229
Moisture Absorption of Matrix Composites by ASTM D5229
Also covered are procedures for conditioning test coupons prior to use in other test methods; either to an essentially moisture-free state, astm d5229 equilibrium in a standard laboratory atmosphere environment, or to equilibrium in a non-laboratory environment. 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.
Link to Active This link will always route to the current Active version of astm d5229 standard. ASTM D testing provides a astm d5229 of procedures in order to determine the moisture absorption or disorption properties. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not astm d5229 as part of the standard.
This procedure is repeated until there is no discernable increase in specimen weight.
ASTM D5229/D5229M – 14
While the test procedures themselves may be used for multi-phase materials, the calculations used to determine d529 moisture diffusivity constant in Procedure A are applicable only to single-phase materials. It is the responsibility of the user of this standard to establish appropriate safety astm d5229 health practices and determine the applicability of regulatory limitations prior to astm d5229.
Immersion in a liquid bath should be used to simulate vapor exposure only when apparent astm d5229 properties are desired for qualitative purposes. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.

The specimens are then dried, removed from the drying oven, and allowed to cool in a desiccator. Touchstone Research Laboratory, Ltd. This procedure will result in the diffusivity constant, Dz and the moisture equilibrium content, Mm at the given moisture exposure level and temperature. Multiple tests at astm d5229 moisture exposure levels are required to establish the dependence astm d5229 M m on moisture exposure level.
