The American National Standards Institute approved the standard in August 2007; ASHRAE approved it in March. Standard 210-07, "Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating," is now available.
The Air Movement and Control Assn.ting Fans for Certified Aerodynamic Performance Rating.”
According to AMCA officials, this standard establishes uniform methods for laboratory test of a fan or other air-moving device to determine its aerodynamic performance in terms of airflow rate, pressure developed, power consumption, air density, speed of rotation, and efficiency for rating or guarantee purposes.
This standard applies to a fan or other air-moving device when air is used as the test gas with the following exceptions:
(a) air circulating fans (ceiling fans, desk fans);
(b) positive pressure ventilators;
(c) compressors with inter-stage cooling;
(d) positive displacement machines;
(e) test procedures to be used for design, production, or field testing.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
