HSA currently performs corrosion coupon evaluations (optical, scanning electron microscopy and weight loss measurements) and manufactures corrosion coupons, both weight loss (WL) and electron microscopy (EM) coupons.
HSA has been analyzing both EM and the more common weight loss coupons since 2010.
The analysis is performed as per our customers' requirements, but generally consists of cleaning the coupons using an inhibited acid solution (NACE Standard RP0775-2005 Item No. 21017), macroscopic photography, optical analysis (NACE Standard TM0169-2000 Item No. 21200) and weight loss measurements.
