ASTM E595 Outgassing Services
Engaged in testing virtually every material, component and system on commercial aircraft, Element’s deliverable is mission critical, certainty. Condensation from this process can collect on sensors, electronics and navigational equipment, causing damage to mission-critical equipment. To obtain these values, multiple samples of this post-conditioned, nickel-graphite filled silicone were tested.
Outgassing, EMI Silicones, and ASTM E
The independent testing agency also determined that the average WVR was 0. In medical environments such as hospitals, AMCs can contaminate sterile surfaces.
With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection.

Because outer space is a vacuum, engineers must also account for how released gases can condense on camera lenses. Discover perspectives, resources, and advice from our world-leading Engaged Experts. Dark gray in color, SSP comes in continuous rolls and can be supplied in thicknesses from 0. Most frequently associated with volatile materialsoutgassing occurs when gases asym vapors are released from polymers and elastomers at above-ambient temperatures.

The vials must be capped before removal from the conditioning chamber. Ready to request a quote? Facebook Twitter Email Other.
Two parameters are measured: These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubings, adhesives, coatings, fabrics, tie cords, and lubricants. 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 e55. Our ASTM E testing services are critical to the material selection process for high vacuum applications.
Therefore, subsequent functional, developmental, and qualification tests should be used, as necessary, to ensure that the material’s performance is satisfactory. In addition to measuring outgassing levels, our experts can provide atm and data about residual gas analysisthermal properties and other aerospace properties. The user may designate additional tests to qualify materials for a specific application.
Outgassing in high-vacuum environments can disrupt electronic equipment and optical devices. 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.
