ASTM E595 Outgassing Services

Historically, TML of 1. 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. Most frequently associated e59 volatile materialsoutgassing occurs when gases and vapors are released from polymers and elastomers at above-ambient temperatures.

Because outer space is a vacuum, engineers must also account for how released gases can condense on camera lenses. To obtain these values, multiple samples of this post-conditioned, nickel-graphite filled silicone were tested. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Make an inquiry today. Engaged in testing virtually every material, component and system on commercial aircraft, Element’s deliverable is mission critical, certainty.

The independent testing agency also determined that the average WVR was 0. Dark gray in color, SSP comes in continuous rolls and can be supplied in thicknesses from 0.

Condensation from this process can collect on sensors, electronics and navigational equipment, causing damage to mission-critical equipment.

Engage with an expert today. For example, materials that release high levels of airborne molecular contaminants AMCs can degrade the performance of sensors and circuit boards in satellites. The fill material for SSP also costs less than silver-aluminum, silver-copper, or silver-glass. Samples tested at other temperatures may be compared only with other materials which were tested at that same temperature. 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.

Two parameters are measured: Link to Active This link will always route to the current Active version of the standard.

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.

Outgassing ast, high-vacuum environments can disrupt electronic equipment and optical devices.

For engineers who need low outgassing compounds with the right balance of properties, post-conditioned SSP is an excellent choice. Ready to request a quote? This website uses cookies to improve user experience. Historical Version s – view previous versions of standard.

With the ability to cause damage and failure to mission-critical components, outgassing is an important characteristic to be considered in material selection. ASTM E defines testing procedures for evaluating changes in material mass caused by outgassing in high-vacuum environments. 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.

In medical environments such as hospitals, AMCs can contaminate sterile surfaces. The overall mass e59 can be classified into noncondensables astk condensables.
