(3) At Labelling The standards require that each container bear a label or marking with the following information: • • • • manufacturer's name and lot number; name of the contents; quantity in the container; expiry date after which the material should not be used when stored according to the manufacturer’s instructions; and • brief instructions as to the storage and care of the material prior to use. National Building Code of Canada (NBC) NBC References There is no direct reference to these standards in the National Building Code of Canada 2005, however the CSA O112 Series-M1977 (R2001) standard is referenced in CAN/CSA-O86-01, which is referenced in Table 4.1.8.9. and Sentence 4.3.1.1.(1) Division B of that Code. 10 of 10...
