... Military equipment must be designed to operate in various exposure conditions; therefore, the test programs evaluating them must ensure that the corrosion resistance of base materials and assemblies will be sufficient. These conditions include rain, humidity, bowing/settling sand, debris, salt...

... (air or argon), control aids (desiccant, oxygen scavenger, or none), and external environment (BOC/Linde ADDvance inert gas powder cabinet, humidity/temperature controlled lab, or outside). In the second part of the study, electron beam power bed fusion/Ti6‐Al‐4V powder was stored for 8 months in two...

... When building materials are in contact with indoor air they have some capacity to moderate the variations of indoor humidity in occupied buildings. But, so far, there has been a lack of a standardized quantity to characterize the moisture buffering capability of materials. It has been...

... the reduced sulfosulfuron efficacy associated with low humidity. Sodium lactate and calcium nitrate enhanced sulfosulfuron efficacy regardless of spray mixture pH, but the increase appeared greater at low pH (4.3–5) than at high pH (7.7–8.2). Scanning electron micrographs showed that spray deposits at low pH...

... the aircraft and to evaluate other factors that could affect the comfort of the aircraft occupants. Parameters measured include: volatile and semivolatile organic compounds, aldehydes, carbon dioxide, carbon monoxide, oxygen, relative humidity, temperature, and airflow. The airline evaluated the test results...

... condensation, moisture content of layers and surface relative humidities; dynamic methods also predict the duration of moisture excursions, providing a basis for moisture damage risk assessment. Recognizing that practitioners are not generally trained to use available analytical tools, the Building Environment...

.... This necessitated the computation and tabulation of surface temperatures, dew point temperatures, vapor pressures and relative humidities at various structural components of the insulated assemblies, particularly near the outer skin. condensation air-vapor retarder vapor pressure vapor resistance thermal...

... An important consideration in the evaluation of personal protective equipment is the physical environment which the equipment will encounter during use. For many materials used in protective clothing, the effect of elevated humidity on protective capacity may be negligible. For protective...

.... Combined with high indoor or outdoor humidity, such walls may accumulate excessive amounts of moisture. However, more data were needed on airflows in and through wall assemblies and the effect of airflows on moisture conditions in walls. Twenty wood frame walls of ten different designs, characteristic...

... Simulated aircraft structural joints using CFRP adherends and a supported (for bond thickness control) and an unsupported version of a 120°C epoxy adhesive were fatigued at five different combinations of temperature and humidity. These combinations were: ambient dry, and at 85%RH, 90°C dry...

... or during 30 years of exposure to sunlight/darkness cycles in low earth orbit (LEO). This paper summarizes investigations into the effects of temperature and humidity on coating stresses and cracking. Experimentally measured coating residual stresses after anodizing and sealing are shown to be strongly...

.... Subsidiary experiments showed a large effect of humidity on wear with high wear rates at low humidity levels. The measure of wear with the best repeatability was scar size measurements at 5%, and the worst was mass loss measurements at 42% (expressed as ratios of 95% confidence intervals to the mean values...

... with UVB313 bulbs. No significant degradation occurred with samples exposed to 100% humidity at 30°C (86°F) or 50°C (122°F) with the exception of loss of adhesion to the precast concrete. This study provides the framework of a test method to screen perimeter sealants for durability and reversion resistance...

... The purpose of this study was to evaluate the effect of three conditions of temperature and humidity on pesticide penetration through the fabric. Two fabrics were used, a 100% cotton and a 50/50 cotton/polyester. The three conditions used were 29°C (85°F) with 75% relative humidity (RH), 22°C...

.... A dynamic model is required to predict the resulting attic air humidity ratio. Hourly moisture flows in a typical attic—from ventilation and from the wood—are examined, and a simple first-principles dynamic mathematical model to relate them is developed. The model predicts the hour-by-hour attic air...
