(1) The obligatory applicant of boards commodity should mark the commodity inspection mark on
each piece of body or the minimum pack; the obligatory applicant of wall papers commodity should
be marked on the body or the unit pack itself.
(2) The ones adopting monitoring inspection should be marked with the commodity inspection mark
on the outer pack or unit pack, where there should be the manufacturing date or lot number on the
body, and the obligatory applicant should fill and declare the manufacturing date or lot number of
said batch of commodities in the lot number field of the inspection application form in detail, the
inspection authority that accepts the application for inspection should list the manufacturing date or
lot number in the monitoring inspection certificate with detailed remarks .
(3) The commodities with monitoring inspection adopted should use the commodity inspection
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.
