Dark gray in color, SSP comes in continuous rolls and can be supplied in thicknesses from 0. In medical environments such as hospitals, AMCs can contaminate sterile surfaces. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The user may designate additional tests to qualify materials for a specific application. 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. The fill material for SSP also costs less than silver-aluminum, silver-copper, or silver-glass.
Because outer space is a vacuum, engineers must also account for how released gases can condense on camera lenses.
Outgassing, EMI Silicones, and ASTM E

ast Condensation from this process can collect on sensors, electronics and navigational equipment, causing damage to mission-critical equipment. The vials must be capped before removal from the conditioning chamber. E59 can provide you with critically important data on your product or part’s performance in response to typical or extreme environmental stresses and conditions.
Samples tested at other temperatures may be compared only with other materials which were tested at that same temperature. The overall mass loss can be classified into noncondensables and condensables.
Therefore, subsequent functional, developmental, and qualification tests should be used, as necessary, to ensure that the material’s performance is satisfactory. 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. Make an inquiry today. Historical Version s – view previous versions of standard. Most frequently associated with volatile materials astmm, outgassing occurs when gases and vapors are released from polymers and elastomers at above-ambient aztm.
Historically, TML of 1. It is sufficient that the pressure be low enough that the mean free path of gas molecules be long in comparison to chamber dimensions.
For engineers who need low outgassing compounds with the right balance of properties, post-conditioned SSP is an excellent choice. 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.

With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection. Terms and Conditions of Sale Contact. Engaged in testing virtually every material, component and system on commercial aircraft, Element’s deliverable is mission critical, certainty. Our deliverable is certainty ast high quality data, test reports and certificates that you can absolutely rely on when making decisions about your materials and compliance.
ASTM E defines testing procedures for evaluating changes in material mass caused by outgassing in high-vacuum environments.
Previous Post Next Post. Ready to request a quote? The independent testing agency also determined that the average WVR was 0. In addition to measuring outgassing levels, our experts can provide testing and data about residual gas analysisthermal properties and other aerospace properties.
These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubings, adhesives, coatings, fabrics, tie cords, and lubricants. For example, materials that release 5e95 levels of airborne molecular contaminants AMCs can degrade the performance of sensors and circuit boards in satellites.
ASTM E595 Outgassing Services
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.
Through optional post-conditioning, SSP can supply this nickel-graphite EMI elastomer in a low-outgassing grade upon request. For more information about our ASTM E outgassing s595, or to request a quote, contact us today.
