ASTM D2340 – Standard Test Method for Peroxides in Styrene Monomer
Description:
Significance and Use
4.1 This test method is suitable for determining the quantity of peroxides in styrene monomer both for quality control and quality assurance of the product.
Scope
1.1 This test method covers the determination of the peroxide content of styrene monomer reported as hydrogen peroxide.
1.2 This test method has been found applicable to the determination of peroxides in styrene monomer in the range of 1 mg/kg to 60 mg/kg. Based on the precision data in 12.1, LOD is 6 mg/kg and LOQ is 21 mg/kg.
1.3 In determining the 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 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
