Why CodeMark matters

CodeMark is a voluntary building product certification scheme administered for the Australian Building Codes Board. A CodeMark Certificate of Conformity confirms that a product meets the Building Code of Australia requirements it is certified against, giving builders, designers and building surveyors a clear basis for approval. Scheme rules are available at abcb.gov.au.
