Patrick J. Brennan, 60, vice president of Q-Lab Corp., Westlake, OH, died Sept. 20, 2009. During his 30-year Q-Lab career, he established himself as one of the few experts in the field of accelerated weathering and lightfastness.  He was an active member of the ASTM, ISO, and AATCC standards-making organizations.

Brennan was an active member of AATCC for 23 years, participating in several research committees and as a member of the International Test Methods Committee. He was instrumental in changing Test Method 16 to a performance-based standard.  He was former chair of the Weather Resistance Test Methods and the Colorfastness to Light Test Methods committees, and served as the U.S. expert for the ISO light stability and weathering committee for several years. He also served on ISO TC38 for textiles, and ISO TC61 for plastics from 1992-2005. 

Brennan started his career at Q-Lab working on the Q-Panel line and assembling QUVs.  Later, as the leader of sales and marketing at Q-Lab, he oversaw the initial launch of the Q-Fog Cyclic Corrosion Chamber (1993), Florida and Arizona Weathering Research Service (1995), and Q-Sun Xenon Test Chamber (1998).  Over the past 25 years, he has overseen the global expansion of Q-Lab into more than 60 countries, including the opening of Q-Lab China and Q-Lab Germany.
