Multiple tests at differing moisture exposure levels are required to establish the dependence of M m on moisture exposure level. While intended primarily for laminated polymer matrix composite materials, these procedures are also applicable to other materials that satisfy the assumptions of 1.

This is a gravimetric test that monitors the change in moisture content over time. Global Reach Aztm is the industry leader with over 43, people in 1, locations in over astm d Also covered are procedures for conditioning test coupons prior to use in other test methods; either to an essentially moisture-free state, to equilibrium asstm a standard laboratory atmosphere environment, or to equilibrium in a non-laboratory environment.

Other examples of materials and test conditions that may not meet the astm d are discussed in Section 6. Also included are procedures for determining the moisture loss during elevated temperature testing, as well as moisture loss resulting from thermal exposure after removal from astm d conditioning environment, such as during strain gage bonding. 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.

Procedure B covers general moisture conditioning of material coupons prior to any other material property testing. Multiple tests at differing moisture exposure levels are required to establish the dependence of M m on moisture exposure level. These latter environments may have different material diffusion characteristics. Combining values from the two systems may result in nonconformance with the standard.

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. While intended primarily for laminated polymer matrix composite materials, these procedures are also applicable to other materials that satisfy the assumptions of 1.

The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

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. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Need help or have a question?

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. 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.

Properties determined in the latter manner shall f5229 d reported as apparent properties. Within ASTM D there are three other procedures d522 material conditioning within a specific moisture environment. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Moisture Absorption of Matrix Composites ASTM D is a gravimetric test method that monitors change over time of moisture content by measuring the total mass change of a coupon that is exposed to a specified environment. Procedure A covers the determination of the two Fickian moisture diffusion material properties, the moisture diffusitivity constant and moisture equilibrium content. The specimens are removed from the conditioning environment periodically, allowed to equilibrate to room temperature in a sealed container, and weighed.

This procedure is repeated until sstm is no discernable increase in specimen weight.
