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 xstm humidity environment.

Engage with an expert today. In medical environments such as hospitals, AMCs can contaminate sterile surfaces. The independent testing agency also determined that the average WVR was 0. Engaged in testing virtually every material, component and system on commercial aircraft, Element’s deliverable is mission critical, certainty. Ready to request a quote? For example, materials that release high asstm of airborne molecular contaminants AMCs can degrade the performance of sensors and circuit boards in e955.

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. Samples tested at other temperatures may be compared only with other materials which were tested at that same temperature.

The fill material for SSP also costs less than silver-aluminum, silver-copper, or silver-glass. atm

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. Link to Active This link will always route to the current Active version of the standard.

ASTM E595 Outgassing Services

Condensation from s595 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. The user asttm designate additional tests to qualify materials for a specific application. 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.

Because outer space is a vacuum, engineers must also account for how released gases can condense on camera lenses. This website uses cookies to improve user experience.

Through optional post-conditioning, SSP can supply this nickel-graphite EMI elastomer in a low-outgassing grade upon request. The overall mass loss can be classified into noncondensables and condensables.

ASTM E defines testing procedures for evaluating changes in material mass caused by outgassing in high-vacuum environments. The vials must be capped before removal from the conditioning chamber. Historical Version s – view previous versions of standard.

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. Discover perspectives, resources, and advice from our world-leading Engaged Experts.

Outgassing in high-vacuum environments can disrupt electronic equipment and optical devices. Previous Post Next Post. With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection.

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. 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.
