UNE 81599:2014

This standard describes the procedure and equipment for the determination of the airborne particles at the workplace through the sampling on an appropriate collection substrate and their gravimetric quantification. The standard is applicable to all of the airborne particles whose analysis requires gravimetric determination and it allows the determination of the health related fractions defined in UNE-EN 481 when the appropriate aerosol samplers were used. 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 481, 4.2) and screening measurements of variation of concentration in time and/or space (see UNE-EN 481, 4.3).
