Outgassing Testing Services Prevents Critical Errors A Parylene coating protects 20 printed circuit boards on the Japanese spacecraft Hyabusa2, which, in February 2019, touched down briefly on an asteroid to collect the first of multiple planned samples before its return to Earth, scheduled for 2020. EP17HT-LO Many optical applications where outgassing can cause fogging on highly sensitive parts is also prone to need low outgassing materials. With specialized outgassing services, such as headspace analysis, Innovatech Labs is a uniquely qualified material testing lab. Montana State Universitys PrintSat satellites housing (left) is made with 3D-printed Windform material, as is a hybrid rocket engine built by Experimental Propulsion Lab (right). EP21TDCHT-LO The outgassing test is conducted in a vacuum of 10 Torr at a temperature of 125 Centigrade with a test exposure time of 24-6 o hours. NASA has established requirements that The test measures under high vacuum, the time varying Molecular mass loss of a material sample held at Several bench top ovens being used in a long-term heat aging test of plastic materials.

Parylene HT, the most recent type to be tested by NASA, is for the highest-temperature applicationsfor instance, offshore and down-hole exploration sensors and feedback devices, where outgassing characteristics are usually less of a consideration. Outgassing testing is a means of material testing in which a product is evaluated for the potential of emitting volatile organics upon heating or over time. If a substance gets heated up and gives off condensable volatiles, in a vacuum, theyre going to be drawn right onto cold surfaces, says Debbie Thomas, a senior materials engineer with Ball Aerospace, who has run the Outgassing Laboratory as a contractor at NASAs Goddard Space Flight Center for the last 15 years.

Thomas says she has received emails from Taiwan, Europe, and elsewhere. Parylenes ability to conform completely to the surfaces they cover make them ideal coatings for circuit boards and other electronics to prevent corrosionparticularly, but not only, in the harsh environment of space, where they have been used for decades. Outgassing, also known as offgassing, is a normal process for many manufactured products.

Materials to be tested include but are not limited to bagging materials, tapes, seals, adhesives, nonmetallic containers and covers. Supreme 112, EP21AOLV-2LO This was the result of offgassing: volatile compounds in the vinyl, excited by the trapped heat, escaped into the air and condensed on cooler surfaces. NASA Project Life Cycle. While some outgassing is normal, it can cause air pollution and even product contamination that can lead to product failures. Supreme 42HT-2ND Black IDC or Crimp? This gas will eventually condense on other materials, and could render them inoperable. This technique is ideal for detecting residual solvents, unreacted monomers and other low molecular weight contaminants. Parylene coatings are ultrathin and pinhole-free and fully conform to components through molecular-level polymerizationthey essentially grow onto a surface, one molecule at a time, according to SCS.

When either of those two occur, outgassing of an adhesive can be a major problem and can lead to major failures. EP112FLAO-1 And people do look. In addition to testing materials for NASAs projects, until a couple of years ago, the lab also offered testing to outside entities as space and schedules allowed. Fourier Transform Infrared Spectroscopy. Water absorption is in most cases reversible and can be controlled by purging of critical hardware with dry gases. The condensable materials were . The ASTM E595 outgas test (Standard Test Method for Total Mass Loss and Collected Volatile Condensable Materials from Outgassing in a Vacuum Environment) is a screening technique to determine the percent volatile contact of materials (organic, polymeric, inorganic) when exposed to a vacuum environment (less than 5 x 10 -5 torr) at elevated tempe.
During the E595 test, small samples of material are kept under vacuum and heated to 125C for a 24-hour period. The RS-25 dates back to the late 1970s . NASA Databases. EP41S-5LV EP13LTE Outgassing is what happens when components, such as adhesives or polymers, emit volatile organics when exposed to heat.
NTS Re-Engineers Outgassing Analysis Service to Better Support the EP40 EP42HT-2LTE This is why NASA has been testing substances for outgassing since 1967, compiling a publicly available database with tens of thousands of entries for low-outgassing materials suitable for space.

EP110F8-5 For more information on outgassing testing, contact Innovatech Labs today.
If coatings or other materials outgas, as the phenomenon is commonly called, in the vacuum and extreme temperatures of space, weights can change, throwing off flight calculations, and the gases can resettle, coating nearby surfaces with a film, potentially obstructing sensors, cameras, and other optical equipment. Most of the outgas testing is conducted by materials engineers for Goddard Space Flight Center using a system that is a "diffusion pumped facility" with "a glass cylindrical bell jar containing the outgassing test apparatus specified in ASTM E595-93." (Illustration 1) Illustration 1 This testing system is known as an "ASTM E595" test.

Its a way to legitimize, if you will, at the highest level, the value of the coatings, says Molin. Historically, a TML of 1.00% and CVCM of 0.10% have been used as screening levels for rejection of spacecraft materials. Supreme 11HT-LO Outgassing usually happens when components, such as adhesives or other polymers, are exposed to heat. The process can print almost any shape as one solid object, create multiple objects simultaneously, and ensure the absence of voids in the material that can occur with other additive manufacturing processes. UV22DC80-1 To measure the outgassing of materials such as Parylene coatings, NASA uses a standardized method developed by the American Society for Testing and Materials (ASTM).
In dynamic headspace analysis, the sample is sealed in a vessel which is purged with gas while its being heated. Theyre used in hypodermic and acupuncture needles, as well as surgical tools.

To pass NASA outgassing standards, materials cannot have a TML of >1.0% and a CVCM of >0.1%. NASA outgassing has a specific set of standards to meet demanding applications. These early forays into the space industry have also led the company to work with the European Space Agency and the Japan Aerospace Exploration Agency, although they each ran their own outgassing tests. With over 50 years of experience, White Sands Test Facility houses unique and comprehensive testing and analysis capabilities for evaluating material, component, and system behaviors in hazardous environments. EP42HT-2AO-1 BLACK, EP21LSCL-1 The problem is only exacerbated by the fact that a crafts colder surfaces include crucial components such as lenses, mirrors, and windows. (Some materials have been tested multiple times to ensure accurate data and to allow for changes in formulations of the materials over time.). The NASA outgassing database listed in the resources list for this topic is extensive and a good place to start your search for this data. Windform materials have also been used in a number of satellites built by students, such as Stanford Universitys Stanford Nano Picture Satellite, the KySat-2 CubeSat built by students at the University of Kentucky and Morehead State University, and Montana State Universitys PrintSat, although that one was lost to a failed rocket launch.
