mark printed by the BSMI; the commodities with registration of product certification adopted

should use the commodity inspection mark printed by itself.

 

20. For the boards commodity that should have marked items provisioned by the Chinese National

standardized marks on each piece of product, except for the marked items that should have the

production country or region marked in traditional Chinese characters, with other items that may be

marked in either Chinese or English. The outer pack of the commodity should still be marked with

Chinese in compliance with clause 11 of the The Commodity Inspection Act.

 

21. For the Dressed rockwool boards for acoustic use or Rock wool sheathing boards with a density

below 160kg/m3, the application of exemption from inspection of bending strength or flexural

strength to the BSMI is possible by being in compliance with the international standards project. For

the ones with the exemption from inspection of bending strength or flexural strength and with

qualified examination, the inspection authority should add, "Exemption from inspection of bending

strength or flexural strength" in the remarks field of the monitoring inspection certificate or

registration of product certification certificate.

 

22. For the fire-retardant building materials with thickness larger than the minimum thickness

provisioned by the Chinese National Standards and with thickness levels not defined by the Chinese

National Standards, if no product related provisions are defined in the Chinese National Standards,

then various items examination provisions with respect to the approximately smaller thickness of

the Chinese National Standards are referenced for the examination.  If there is significant

unevenness on the surface, that portion should not be considered when measuring thickness, but if it

is not easy to disregard it while measuring thickness, the minimum value for the thickness

measurement shall used to determine the specified value as referenced.
