The test is performed by placing 300 mL of biodiesel in a 500-mL glass bottle. The sample is then set in a liquid or air bath or chamber at 40 °F for 16 hours. The sample is then allowed to come to room temperature(around 70 °F) and filtered through a 47-mm diameter and 0. 7-μm nominal pore-sized glass fiber filter under vacuum of 25 inches of mercury under atmospheric pressure. The time required to filter 300 ml of biodiesel is reported.  3, fiche 3, Anglais, - cold%20soak%20filtration%20test

Essai de filtration par trempage à froid (EFTF) – Exigence la plus présente dans l’ASTM [American Society for Testing and Materials] D6751. Elle a été ajoutée en 2008 à la suite de l’obtention de données indiquant que certains mélanges de type B100 pouvaient former des précipités au-dessus du point de trouble. Dans des mélanges de pétrodiesel allant jusqu’à une teneur de 20 %, un mélange de type B100 satisfaisant aux exigences de la filtrabilité par trempage à froid ne forme aucun précipité.  2, fiche 3, Français, - essai%20de%20filtration%20par%20trempage%20%C3%A0%20froid

A thermal vacuum test on the first flight vehicle of the H-II Transfer Vehicle(HTV) has been carried out at the Spacecraft Integration and Test Building at the Tsukuba Space Center. The purpose of the test is to evaluate the thermal design of the structure and to verify its endurance in the harsh environment of space by stimulating the vacuum and thermal environment in space. Thermal vacuum test for the Pressurized Carrier and Unpressurized Carrier have already been completed, and the main part of Avionics Module and Propulsion Module combined is now in the 13-meter diameter space chamber for testing.  2, fiche 5, Anglais, - thermal%20vacuum%20test

The Rocket Assembly/Checkout Facility... The facility consists of six contiguous laboratory modules subdivided into a storage area, a gray room area, and a clean room. The storage area houses spare instrument components and intermittently used ground support equipment. The gray room area contains facilities to clean components before they enter the clean room and equipment used to ship the instrument to WSMR [White Sands Mission Range]. The Class 100 cross-flow clean room is separated from the gray room by an air shower. The clean room contains three major stations : a clean bench for assembly of subsystems; a 12x14-ft optical bench for instrument assembly and electronic test of the instrument subsystems; and a vacuum chamber for vacuum focus and spectroradiometric calibration. The cryogenically pumped vacuum chamber is designed with a 30-cm diameter ultraviolet collimator at one end and a roll-off section that accommodates the entire flight instrument centered in the collimated beam at the other end.  2, fiche 6, Anglais, - clean%20bench

Thermal Vacuum Test Chamber... The purpose of the Thermal Vacuum test is to verify that the satellite will work correctly in the extreme temperatures and low pressures experienced in space. The satellite is suspended from a test fixture in the center of the tank, which is pumped out to a pressure about a billion times smaller than atmospheric pressure. The entire chamber wall can be heated and cooled to simulate the effects of solar heating when the satellite is in sunlight and the cold of outer space when the satellite is in the shadow of the Earth.  3, fiche 7, Anglais, - vacuum%20test%20chamber

Seam Testing Methods... Vacuum chamber(boxes) have been used where a 3-ft-long box with a transparent top is placed over the seam and a vacuum of approximately 2. 5 lb/in. superscript 2] applied. When a leak is encountered the soapy solution originally placed over the seam shows bubbles. These bubbles are due to air entering from beneath the liner and passing through the unbonded zone. The test is slow to perform and it is often difficult to make a vacuum-tight joint at the bottom of the box where it passes over the seam edges.  1, fiche 9, Anglais, - vacuum%20box
