ASTM D2119 – Standard Test Method for Aldehydes in Styrene Monomer
Description:
Significance and Use
4.1 This test method is suitable for determining the quantity of aldehydes, both for quality control and quality assurance of the product.
Scope
1.1 This test method covers the wet chemical determination of aldehydes in styrene monomer. Aldehydes are calculated and reported as benzaldehyde.
1.2 This test method is applicable to samples with aldehyde concentrations to 0.030 mass%. The limit of detection (LOD) is 0.0006 mass% and the limit of quantitation (LOQ) is 0.002 mass% based on the data in 13.1.
1.3 In determining conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
