Standard 62 overview.

Air quality on commercial aircraft.

ASHRAE is developing a standard to ensure cabin air quality 1) is safe for flight and occupants; 2) minimizes the potential for adverse health effects; and 3) is comfortable to occupants. ASHRAE Technical Committee 9.3, Transportation Air Conditioning, issued a work statement for the study, "Relate Air Quality and Other Factors to Symptoms Reported by Passengers and Crew on Commercial Transport Category Aircraft." The study's purpose is to support the development of ASHRAE Standard Project Committee 161P, Air Quality in Transport Category Commercial Aircraft. 

Evaluation of air terminal units test methods: influence of inlet parameters on performance.

This study focuses on the way to apply CEN test methods to a full range of air diffusers and is dedicated to the improvement of these methods proposed by the CEN TC l 56/WG4 of which both authors are members. Air terminals of different sizes have been tested on aerodynamic and acoustic aspects both in a Spanish and a French laboratory. The tests were made according to pr EN 12238 ''Air Terminal devices - Aerodynamic testing and rating for mixed flow applications" and to EN 25135 (ISO 5135).

Ventilation hygiene standards - an overview.


Ventilation for buildings - Design criteria for the indoor environment.

This Technical Report has been prepared by Technical Committee CEN/fC 1 56, Ventilation for buildings. This Technical Report is intended to assist in providing an acceptable indoor environment for people in ventilated buildings.This Technical Report specifies the requirements for, and methods of expressing the quality of the indoor environment for the design, collllllissioning, operation and control of ventilation and airconditioning systems. This Technical Report covers indoor environments where the major concern is the hwnan occupation but excludes dwellings.
