3、 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard.The UK Committee believes that a more comprehensive approach to the qual-ification of thermoplastics under realist

4、ic conditions for the oil and gas sector is possible through using BS EN ISO 23936-1 in association with other codes for the following instances:When deciding on test methodology for large applications refer to API Technical Report 17TR:2003.

6、23 for wellhead applications and BS EN 13942 (ISO 14313 modified) for valve applications.The hydrocarbon mixture in the simulated production mixture can be found in Table B.1 in this standard. If a UK user should consider that the oil to be simulated for the area of interest is so different from the

7、 one in Table B.1 that incorrect liquid absorption characteristics would be measured when testing, then the latest revision of NORSOK standard M-710 referring to thermoplastics and elastomers contains a range of similarly-devised optional hydrocarbon mixtures.Guidance can also be found in BS EN ISO
