Work with the latest criteria in the 2011 NFPA 262 for accurate assessments of smoke and fire spread. NFPA 262: Standard Method of Test for Flame Travel and Smoke of Wires and Cables for Use in Air-Handling Spaces presents a test procedure to evaluate the potential for fire spread along cables and wires housed in a plenum or other environmental space. The methodology measures both flame travel distance and optical density of smoke. Among the changes in the 2011 edition:     * Revisions to removable top cover protection     * Revisions to create consistency with ASTM E 84     * Added new methods to determine average airflow velocity     * Moved Reference Cable Test into an Annex Invest in fire safety by following the up-to-date testing guidelines in the 2011 NFPA 262.
