Sets out a spectrophotometric method for the determination of formaldehyde in indoor air using impinger collection. This method is applicable to indoor air in which the expected formaldehyde concentration is within the range of 0.01 ppm to 1 ppm. Sampling periods of 1 h to 4 h are normally used.

This Standard sets out a spectrophotometric method for the determination of formaldehyde in indoor air using impinger collection. The method is applicable to formaldehyde concentrations in air in the approximate range 0.01 p.p.m. to 1 p.p.m. Sampling periods of 1 h to 4 h are normally used.NOTE: Phenol results in significant negative interference if present at more than about 30û40% of the formaldehyde concentration. This method is not recommended if it is known or suspected that phenol may be present. Other substances reported to cause negative interference, if present in concentrations in excess of the formaldehyde concentration are ethanol, ethylene, propylene, methyl butadiene and some aromatic hydrocarbons, though these chemicals are unlikely to be present at concentrations in excess of formaldehyde.
