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.
Environmental – Pacific Testing Laboratories
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.

The user may designate additional tests to qualify materials for a specific application. Our ASTM E testing services are critical to the material atm process for high vacuum applications.

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.
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.
