According to the Federal Aviation Administration (FAA), nearly 10 million domestic and international flights took to the skies in 2010, carrying more than 780 million passengers to destinations around the globe. Exterior aircraft position lights - used to signal the size of the aircraft, its direction of travel, and approximate rate of travel - are critical to ensuring the safety of passengers, flight attendants, pilots, and ground crew.
A recently published aerospace standard, SAE AS 8037B-2011, Minimum Performance Standard for Aircraft Position Lights, establishes minimum performance requirements for new equipment position lights. This standard from ANSI organizational member and accredited standards developer SAE International defines minimum light intensity requirements (in both vertical and horizontal directions) along the longitudinal, vertical, and lateral axes of the aircraft. The standard also defines color tolerances for the light emitted from the position lights.
SAE International is a global membership organization comprised of engineers and related technical experts in the aerospace, automotive, and commercial-vehicle industries committed to advancing the engineering of safe and environmentally sound mobility systems used in designing, building, maintaining, and operating vehicles for use on land, sea, air, or space.
Swimming Pool Heaters
Kids of all ages view swimming pools as one of the greatest luxuries, whether they're looking for an enjoyable way to cool off on a summer day or want to take part in one of the healthiest forms of exercise. But let's face it: an over- or under-heated pool can take can take all the fun away in a flash.
A newly revised American National Standard (ANS) from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) helps to keep any unwanted surprises out of a diver's splash. ANSI/ASHRAE 146-2011, Methods of Testing Pool Heaters, describes uniform methods of testing and rating pool heaters. Originally published in 1998, the standard provides methods of testing for heating capacity and energy efficiency, and applies to all pool heaters operated by gas, oil, or electricity, including heat pumps using ambient air as a heat source.
ASHRAE, an ANSI organizational member and audited designator, is an international organization that works promote a sustainable world through research, standards, recommended procedures and guidelines, continuing education, and publishing technical information.
