This method is specified using ISO 3308 smoking parameters. This document provides an alternative
method to that specified in ISO 22634-1 with a different clean-up and a shorter total analytical run
allowing a potential increase of sample throughput in comparison with ISO 22634-1.
This method was validated using ISO 3308 smoking parameters and is technically compatible with other smoking regimes.
This document provides an alternative method to that specified in ISO 22634-1 with a different clean- up which is less time consuming and with a reduced analytical run allowing a potential increase of sample throughput in comparison with ISO 22634-1.
This method is for determining phenol at concentrations from 0.1 to 2.0 mass-ppm in light aromatic hydrocarbons such as benzene ethylbenzene cumene toluene and xylene as well as cyclohexane by visible spectrophotometry. Higher concentrations can be determined by diluting the sample. The presence of substituted phenols may cause a positive interference. Aldehydes ketones ethers alcohols amines and sulfur compounds will interfere if present.
1.1 This specification covers a grade of benzene known as Low Toluene Low Dioxane (LTLD) Benzene.
1.2 The following applies to all specified limits in this standard: for purposes of determining conformance with this standard an observed value or a calculated value shall be rounded off x201C;to the nearest unitx201D; in the last right-hand digit used in expressing the specification limit in accordance with the rounding-off method of Practice E29.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 Consult current OSHA regulations supplier''s Material Safety Data Sheets and local regulations for all materials used in this specification.

1.2 The following applies to all specified limits in this standard: for purposes of determining conformance with this standard an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit in accordance with the rounding-off method of Practice E29.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 Consult current OSHA regulations supplier’s Safety Data Sheets and local regulations for all materials used in this specification.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
1.1 This test method covers the determination of the purity of cyclohexane by gas chromatography.
1.2 This test method has been found applicable to the measurement of impurities such as those found in Table 1 which are impurities that may be found in cyclohexane. The impurities can be analyzed over a range of 1 to 400 mg/kg by this method but may be applicable to a wider range.
1.3 The limit of detection is 1 mg/kg.
1.4 In 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.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 This standard does not purport to address all of the safety concerns if any associated with its use. It is the responsibility of the user of this standard to establish appropriate safety health and environmental practices and determine the applicability of regulatory limitations prior to use.
