Samples tested at other temperatures may be compared only with other materials which were tested at that same temperature. It is sufficient that the pressure be low enough that the mean free path of gas molecules be long in comparison to chamber dimensions. Outgassing in high-vacuum environments can disrupt electronic equipment and optical devices. The independent testing agency also determined that the average WVR was 0.

Historical Version s – view previous versions of standard.

For engineers who need low outgassing compounds with the right balance of properties, post-conditioned Ashm is an excellent choice. With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection. The vials must be capped before removal from the conditioning chamber.

The overall mass loss can be classified into noncondensables and condensables. Referenced Astmm 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. Previous Post Next Post. These include polymer potting compounds, foams, elastomers, films, tapes, insulations, shrink tubings, adhesives, coatings, fabrics, tie cords, and lubricants. Through optional post-conditioning, SSP can supply this nickel-graphite EMI elastomer in a low-outgassing grade upon request.

Most frequently associated with volatile materialsoutgassing occurs when gases and vapors are released from polymers and elastomers at above-ambient temperatures.

ASTM E defines testing procedures for evaluating changes in material mass caused by outgassing in high-vacuum environments. 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. The user may designate additional tests to qualify materials for a specific application. Ready to request a quote? After a hour outgas w595, the specimens and the condensing plates are weighed to determine mass loss, and the percentage of the volatile effluents that were collected during testing.

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

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 qstm sensors, electronics and navigational equipment, causing damage to mission-critical equipment. Historically, TML of 1.
