This standard describes the procedure and equipment for the determination in the airborne at the workplace, of the anions of hydrochloric acid, hydrobromic acid and nitric acid, and their mixtures, throught the sampling on a alkali-impregnated membrane filter and the subsequent analysis by ion chromatography.The procedure of measurement described can be used to carry out measurements to determine the occupational exposure concentration, measurements for comparison with limit values (occupational) to evaluate the exposition via inhalation and periodic measurements. It may also be used to carry out screening measurements of time weighted average concentration (see UNE-EN 482, 4.2) and screening measurements of variation of concentration in space (see UNE-EN 482, 4.3). It cannot be used to measure instantaneous concentrations or fluctuations of the concentration in short periods of time
