INSTRUCTIONS TO PARTICIPANTS

  • Please confirm sample receipt as soon as you have received and checked the contents of this package, preferably using the fax form that you receive together with this package. Please complete the form and fax it to i.i.s.(faxno. ++ 31 181 69 4543) or by email ().
  • This interlaboratory study concerns 2different samples of textile (#12162 and #12163) for determination of OPP/PCP in textiles. You receive approx. 5 grams of each sample.Please treat each sampleas if it is a routine sample.
  • Each laboratory is requested to analyse the samples in the way it would normally do in day-to-day circumstances. However, the test parameters should be determined with reference to OEKO-Tex standard 100/1000. Do not analyse separate colours! This may be different as your laboratory is used, but for good comparison we ask you to treat each sample as a monocoloured material.
  • Report the analytical results using the indicated units on the report form. Please report the results with one extra significant figure (if possible). Also do not report ‘less than’-results which are above your detection limit. Results reported as ‘less than’ cannot be used for meaningful statistical calculations.
  • Please complete the report formswith the requested details of the analysis performed.
  • Please return the completed report form to iis in Spijkenisse, The Netherlands, preferably one week after sample receipt, but in any case before the indicated closing date:December 14, 2012(preferably by email).
  • If you have any remarks/questions please contact:
