In addition to measuring outgassing levels, our experts can provide testing and data about residual gas analysisthermal aastm and other aerospace properties. Condensation from this process can collect on sensors, electronics and navigational equipment, causing damage to mission-critical equipment.

Silicones That Work

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.

Discover perspectives, resources, and advice from our ast, Engaged Experts. The user may designate additional tests to qualify materials for a specific application. Therefore, subsequent functional, developmental, and qualification tests should be used, as necessary, to ensure that the material’s performance is satisfactory.

ASTM E defines testing procedures for evaluating changes in material mass caused by outgassing in high-vacuum environments. The fill material for SSP also costs less than silver-aluminum, silver-copper, or silver-glass.

It is sufficient that the pressure be low enough that the mean free path of gas molecules be long in comparison to chamber dimensions. These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubings, adhesives, coatings, fabrics, tie cords, and lubricants.

ASTM E Outgassing Services | Element

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. Two parameters are measured: Outgassing in high-vacuum environments can disrupt electronic equipment and optical devices. Element can provide you with critically important asfm on your product or part’s performance in response to typical or extreme environmental stresses and conditions.

Outgassing, EMI Silicones, and ASTM E

Terms and Conditions of Sale Contact. Most frequently associated with volatile asfmoutgassing occurs when gases and vapors are released from polymers and elastomers at above-ambient temperatures. In medical environments such as hospitals, AMCs can contaminate sterile surfaces.

For engineers who need low outgassing compounds with the right balance of properties, post-conditioned SSP is an excellent choice. Previous Post Next Post.

For more information about our ASTM E outgassing capabilities, or to request a quote, contact us today. Our ASTM E testing services are critical to the material selection process for high vacuum applications.

To obtain these values, multiple samples of this post-conditioned, nickel-graphite filled silicone were tested.


atsm The vials must be capped before removal from the conditioning chamber. The overall mass loss can be classified into noncondensables and condensables. Samples tested at other temperatures may be compared only with other materials which were tested at that same temperature. Engaged in testing virtually every material, component and system on commercial aircraft, Element’s deliverable is mission critical, certainty. Because outer space is a vacuum, engineers must also account for how released gases can condense on camera lenses.

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.

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. The independent testing agency also determined that the average WVR was 0. Engage with an expert today. Dark gray in color, SSP comes in continuous rolls and can be supplied in thicknesses from 0. Through optional post-conditioning, SSP can supply this nickel-graphite EMI elastomer in a low-outgassing grade upon request.
