Historically, TML of 1. Therefore, subsequent functional, developmental, and qualification tests should be used, as necessary, to ensure that the material’s performance is satisfactory.

Outgassing, EMI Silicones, and ASTM E

The user may designate additional tests to qualify materials for a specific application. The independent testing agency also determined that the average WVR was 0. 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 process can collect on sensors, electronics and navigational equipment, causing damage to mission-critical equipment.

Engaged in testing virtually every material, component and system on commercial aircraft, Element’s deliverable is mission critical, certainty. Terms and Conditions of Sale Contact. In medical environments such as hospitals, AMCs can contaminate sterile surfaces.

Historical Version s – view previous versions of standard. The vials must be capped before removal from the conditioning chamber. The overall mass loss can be classified into noncondensables and condensables.


These include polymer potting compounds, foams, elastomers, films, ast, insulations, shrink tubings, adhesives, coatings, fabrics, tie cords, and lubricants. Dark gray in color, SSP comes in continuous rolls and can be supplied in thicknesses from 0.

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. 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.

With materials testing laboratories span from coast to coast in the US, Element’s clients enjoy access to our global platform of aztm capacity, capabilities and experts. Facebook Twitter Email Other. For example, materials that release high levels of airborne molecular contaminants AMCs can degrade the performance of sensors and circuit boards in satellites.

Silicones That Work

ASTM E defines testing procedures for evaluating changes in material mass caused by outgassing in high-vacuum environments. Outgassing in high-vacuum environments can disrupt electronic equipment and optical devices.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Through optional post-conditioning, SSP can supply this nickel-graphite EMI 5e95 in a low-outgassing grade upon request.


Two parameters are measured: It is sufficient that the pressure be low enough that the mean free path of gas molecules be long in comparison to chamber dimensions. In addition to measuring outgassing levels, our experts can provide testing and data about residual gas analysisthermal properties and other aerospace properties. Samples tested at other temperatures may be compared only with other materials which were tested at awtm same temperature. With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection.

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.
