SP INFO 2004:32 2004-09-30

SP Swedish National Testing and Research Institute is the first European organisation to be approved by the Japanese ministry of MLIT for carrying out tests of formaldehyde-emitting materials and for certifying these products in co-operation with a Japanese Institute, JTCCM. Companies that need an approval in accordance with the new Building Standard Law (BSL) for export to Japan can therefore turn to SP for handling the certification process.

The new Japanese building rule, ”Building Standard Law, 1 July 2003”, states for instance that all building materials used indoors must be low-emitting as regards formal-dehyde and that all products that contain glued com-ponents must be tested for formaldehyde. MLIT (Ministry of Land, Infrastructure and Transport) has developed regulations, rules and a number of product-adapted standards (JIS), according to which the products must be tested. A documentation demonstrating the Japanese ministry’s approval and certification of the product must be shown at the final inspection of the building.

Until recently, European exporting companies had to contact agencies or expensive sales companies in Japan in order to get an application for export and to send

material to Japan for test and certification. Today, the exporting companies can instead turn to SP that, in co-operation with the JTCCM Institute, will deal with the whole application process for getting an approval for export to the Japanese market.

The Japanese test methods that are applied are the traditional Japanese desiccator method and a new small-scale chamber method. The product standards show what method and what requirements will apply. For the desiccator method, a result of less than 0.3 mg formaldehyde per litre is required for free use of the product from July 1, 2003, and for the small-scale chamber method an emission rate of less than 5µg/(m2x

h) is required.

Climate chamber methods for determination of formal-dehyde are e.g carried out according to Japanese method JIS A 1901, European standard prEN 717-1 and Swedish standard SS 270236.

Determination of formaldehyde emission from wood-based panels is carried out according to Japanese methods JIS A 1460, JIS A 5905 and JIS A 5908.
