What is BS EN 16143 - Determination of content of Benzo(a)pyrene (BaP) and selected polycyclic aromatic hydrocarbons (PAH) in extender oils about?
BS EN 16143 specifies a procedure for the determination of the content of benzo[a]pyrene (BaP) in extender oils which are commonly used in the rubber industry for the production of tyres or parts of tyres. The method also yields the sum of the eight individual polycyclic aromatic hydrocarbons (PAHs) listed in Table 1.
The procedure has been tested and verified for the PAHs listed in Table 1 (those required by the European Commission [1]) and additional PAHs as listed in Table A.2.
Analysis of other PAHs is possible in principle, but sufficient quality assurance performed by the user is necessary to secure the analysis.
The application range for this method is from approximately 4 mg/kg to approximately 15 mg/kg for the eight individual PAHs and from approximately 0,5 mg/kg to approximately 2 mg/kg for BaP.
Note 1: The intended working range for this method is in the 0,1 mg/kg to 15 mg/kg range. For the lower levels precision has not yet been established.
Who is BS EN 16143 - Determination of content of Benzo(a)pyrene (BaP) and selected polycyclic aromatic hydrocarbons (PAH) in extender oils for?
BS EN 16143 on the determination of the content of Benzo(a)pyrene (BaP) and selected polycyclic aromatic hydrocarbons (PAH) in extender oils is useful for:
- Petroleum industry
- Testing laboratories
- Research institutes/ academia
- Manufacturers/ producers of tyres and extender oils
Why should you use BS EN 16143 - Determination of content of Benzo(a)pyrene (BaP) and selected polycyclic aromatic hydrocarbons (PAH) in extender oils?
BS EN 16143 has been prepared under a mandate given to CEN by the European Commission (EC) [1] and the European Free Trade Association (EFTA). EU Directive 2005/69/EC [2] sets restrictions on the marketing and use of polycyclic aromatic hydrocarbons (PAHs) in extender oils and tyres.
Tyres are produced using extender oils that may contain PAHs not added intentionally. Due to the fact that PAHs can be incorporated during the production process into the rubber matrix, they can be present in various amounts in the final products. The presence of PAHs can be detected qualitatively and quantitatively using benzo[a]pyrene (BaP) as marker. BaP and PAHs are dangerous substances classified according to the Directive 67/548/EEC [3] as carcinogenic, mutagenic and toxic for reproduction.
It has been recognised that this type of very complex trace analysis is very difficult. This is because of the fact that suitable samples are very rare and almost impossible to find.
BS EN 16143 helps you carry out procedures using double LC cleaning and GC/MS analysis for determination of PAHs in extender oils with accuracy and precision.
