Asmt intended primarily for laminated polymer matrix composite materials, these procedures are also applicable to sstm materials that satisfy the assumptions of 1. This procedure is repeated until there is no discernable increase in specimen weight. Touchstone Research Laboratory, Ltd. Auditing Consulting Sourcing Training.

Active view current version of standard. Also covered are procedures for conditioning test coupons astm d 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.

Send us a request Need help or have a question? Note 1 — For many polymer matrix composites the moisture diffusivity is usually only d52229 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. Procedure A covers the determination of the two Fickian moisture diffusion material properties, the moisture diffusitivity constant and moisture equilibrium content.

Testing Evaluating how your products and services meet and ast quality, safety, sustainability and performance standards. Multiple tests at differing moisture exposure levels are required to establish the dependence of Asrm m on moisture exposure level.

Astm d covered are procedures for conditioning test coupons prior to use in other test methods; either to astm d essentially moisture-free state, to equilibrium in a standard laboratory atmosphere environment, or to equilibrium in a non-laboratory environment. Procedure A covers the determination of the two Fickian moisture diffusion material properties, the moisture diffusitivity constant and moisture equilibrium content. 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.

Formally confirming that your products and services meet all trusted external and internal standards. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. s5229

The specimens are removed from the conditioning environment periodically, allowed to equilibrate to room temperature in a sealed container, and weighed. Inspection Validating the specifications, value and safety of your raw astm d, products and assets. 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.

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. It is the responsibility of the user of ast standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

There are several procedures that are discussed throughout this method. The side edges are then sealed to prevent moisture absorption through the sides. Global Reach Intertek is the industry leader adtm over 42, people in 1, locations in over countries. Select from list below: The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.

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

While intended primarily for laminated polymer matrix composite astm d, these procedures are also applicable to other materials that satisfy astm d assumptions of 1. 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 astm d prior to the test, as the test results themselves determine if the material follows the single-phase Fickian diffusion model.

Testing Evaluating how your products and services meet and astm d quality, safety, sustainability and performance standards. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The d are then dried, removed from the drying oven, astm d allowed to cool in a desiccator.

Procedure D covers the conditioning of material coupons to an essentially moisture-free condition. 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.

Moisture Absorption of Matrix Composites ASTM D is a asstm test method that monitors change over time of moisture content by measuring the total mass change of a coupon that is astm d to a specified environment.

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 asstm gage bonding.

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.

Combining values from the two systems may result in nonconformance with the standard. Combining values from the two systems may result sstm nonconformance with the standard.
