Almost 3 years have passed since the first Japanese CLT standard JAS 3079 was established in December 2013.  Most JAS standards are usually revised every 5 years, however MAFF* started its revision work in January of this year.  COFI sits as one of the 16 revision committee members.  Our goal includes to let them revise the standard so that Canadian lumber with species groups can be used as the planks in the JAS-certified CLT.  We also elaborate a plan to make the standard accept North American recipe of the polyurethane adhesive (also see this blog in October, 2015).  The revision work is scheduled to be completed by March 2019.
