Scope

1.1 Subject content
This Standard specifies the acetylacetone spectrophotometric method to measure
formaldehyde in industrial emissions and ambient air.
1.2 Application scope
1.2.1 This Standard applies to emissions in those industries such as resin
manufacturing, coatings, rayon, plastics, rubber, dye, pharmaceutical, plaint, and
tanning. And it also applies to determination of formaldehyde vapor produced when
conducting pharmaceutical disinfection, corrosion, and fumigation.
1.2.2 When the sampling volume is 0.5~10.0 L, the measuring range is 0.5~800
mg/m3.
1.2.3 When formaldehyde concentration is 20 µg/10 ml, coexist 8g of phenol (400
times), 10mg of acetaldehyde (500 times), 600mg of ammonium ion (30000 times)
without interference; coexist SO2, less than 20 µg, NO2 is less than 50 µg, the
recovery of formaldehyde shall not be less than 95％.
