If VOC content is mentioned as per ISO EU standard, is it acceptable for LEED?

Nowfal – I presume you mean ISO 11890-2, as cited in EU Decopaint Directive 2004/42/CE.
Apparently, the EU Directive’s methodologies for measuring VOC content differ considerably from those used in the SCAQMD & CARB Standards referenced in LEED-2009. Therefore, measurements using the European standard may not be valid to show compliance with SCAQMD or CARB VOC limits. See Dwayne Fuhlhage's June 19 post on the LEED-2009 Core & Shell IEQc4.2 page:
http://www.leeduser.com/credit/CS-2009/IEQc4.2?page=0#comment-50943.
On the other hand, under LEEDv4, 2004/42/CE is listed as an alternative to SCAQMD-1113 outside the US. LEEDv4 provides additional guidance for evaluating VOC content internationally. However, the LEED-2009 Global Alternative Compliance Path Guide does not include these alternatives (see http://www.usgbc.org/resources/leed-reference-guide-green-building-desig...).
Global VOC requirements appear to be the hot topic of recent LEEDuser posts. Since USGBC has not addressed this issue under LEED-2009, it may be wise to submit a formal inquiry. We can hope that USGBC will soon issue LEED Interpretations or Addenda that clarify this issue.
