Résumé : |
In the scope of upholstery leather emission evaluation various test specifications on the basis of test chamber examinations are implemented requiring an ambient air concentration hygienic assessment after 3 and 28 days conditioning periods. The quantified VOC test chamber concentrations are compared with defined target values. With increasing frequency, tanneries and the leather processing industry force test institutes into the approach to generate valid ratings of potential contaminant loads by applying short-terra evaluations.
Both the arrangement of an expressive pool of measured data on upholstery leathers and proficiency of measuring time-point related VOC frequency scales and their reciprocal dependences (interdependency) should enable an estimation approach : On the basis of quantified TVOC (Total VOC) and single compound concentrations measured at time-point t1 = 3d a prediction on a derivable probability can be drawn to which extent leather samples may comply with the threshold limits defined for the prolonged evaluation reading point t2 = 28d. From the aspect of a statistical data arrangement, this article summarizes upholstery leather samples VOC test results including discussion of approaches for usage of VOC results extracted from short-term evaluations. |
