Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Element can provide you with critically important data on your product or part’s performance in response to typical or extreme environmental stresses and conditions.

Each specimen must be weighed within 2 min after opening the vial to minimize the loss or absorption of water vapor while exposed to an uncontrolled humidity environment. In medical environments such as hospitals, AMCs can contaminate sterile surfaces. Two parameters are measured: Terms and Conditions of Sale Contact.

In addition to measuring outgassing levels, our experts can provide testing and data about residual gas analysisthermal properties and other aerospace properties. With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection.

Outgassing, EMI Silicones, and ASTM E

Most frequently associated with volatile materialsoutgassing occurs when gases and vapors are released from polymers and elastomers at above-ambient temperatures. The user may designate additional tests to qualify materials for a specific application. For example, materials that release high levels astmm airborne molecular contaminants AMCs can degrade the performance of sensors and circuit boards in satellites.

These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubings, adhesives, coatings, fabrics, tie cords, and lubricants.

The vials must be capped before removal from the conditioning chamber. For more information about our ASTM E outgassing capabilities, or to request a quote, contact us today.

With materials testing laboratories span from coast to coast in the US, Element’s clients enjoy access to our global platform of testing capacity, capabilities and experts. 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. Condensation from this xstm can collect on sensors, electronics and navigational equipment, causing damage to mission-critical equipment.

The fill qstm for SSP also costs less than silver-aluminum, silver-copper, or silver-glass.

ASTM E Outgassing Services | Element

Engage with an expert today. The independent testing agency also determined that the average WVR was 0. Samples tested at other temperatures may be compared only with other materials which were tested at that same temperature.

Our ASTM E testing services are critical to the material selection process for high vacuum applications. It is sufficient that the pressure be low enough that the mean free path of gas molecules be long in comparison to chamber dimensions. Our deliverable is certainty – high quality data, test reports and certificates that you can absolutely rely on when making decisions about your materials and compliance. Previous Post Next Post.

Silicones That Work

For engineers who need low outgassing compounds with the right balance of properties, post-conditioned SSP is an excellent choice. Because outer space is a vacuum, engineers must also account for how released gases can condense on camera lenses. ASTM E defines testing procedures for evaluating changes in material mass caused by outgassing in high-vacuum environments.

Through optional post-conditioning, SSP can supply this nickel-graphite EMI elastomer in a low-outgassing grade upon request. Link to Active This link will always route to the current Active version of the standard. Historical Version s – view previous versions of standard.

Engaged in testing virtually every material, component and system on commercial aircraft, Element’s deliverable is mission critical, certainty. After a hour outgas exposure, the specimens and the condensing plates are weighed to determine mass loss, and the percentage of the volatile effluents that were collected during testing.
