ISO 16000-38:2019 PDF Download

ISO 16000-38:2019 is a standard that establishes a method for determining the concentration of amines (primary, secondary, and tertiary aliphatic and aromatic amines) in indoor air and test chamber air. The method uses active sampling on samplers containing phosphoric acid impregnated filters. The standard specifies the sampling procedure and requirements for determining the mass concentration of amines in the air.

The standard outlines the measurements to be performed using samplers containing phosphoric acid-impregnated inert supporting material, operating at specified flow rates and sampling periods. It also defines the range of application for the concentrations of amines in indoor air, which depends on factors such as gas sample volume, eluate volume, injection volume, and sensitivity of the analytical equipment.

The document can be used for the measurement of amines listed in Annex A, but it can also be applied to the measurement of other amines in indoor air. It describes procedures for the fabrication and use of glass tubes containing impregnated filters made of phosphoric acid-impregnated glass wool as samplers. However, it does not exclude other samplers with equal or improved properties, and it provides procedures for demonstrating the equivalence of other sampler types or methods.

It is important to note that this standard does not cover the determination of amines in other media like water or soil, nor does it cover the determination of isocyanates in indoor air as corresponding amines. Quaternary amines are also not included in this standard.
