ASTM D3160 – Standard Test Method for Phenol Content of Cumene (Isopropylbenzene) or AMS (α–Methylstyrene)
Description:
Significance and Use
4.1 This test method is useful in determining phenol in the range from 5 to 50 mg/kg in commercially available cumene or AMS.
4.2 Phenol will inhibit certain reactions involving cumene or AMS.
Scope
1.1 This test method covers the determination of phenol in refined cumene (isopropylbenzene) or AMS (α–methylstyrene).
1.2 This test method has been found applicable in the range from 5 to 50 mg/kg of phenol in refined cumene (isopropylbenzene) or AMS (α–methylstyrene). The limit of detection (LOD) is 0.9 mg/kg and the limit of quantitation (LOQ) is 2.9 mg/kg.
Note 1: LOD and LOQ were calculated using intermediate precision for the lowest level in the ILS.
1.3 The following applies for the purposes of determining the conformance of the test results using this test 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.
