There are performance differences documented by third party testing agencies which can be used to demonstrate superior performance of Universal Plus and Universal Gold compared to the competition. To successfully extinguish a flammable liquid fire we must apply the correct amount of finished foam to the fuel surface in a designated amount of time for extinguishment. The rates are found in the NFPA 11 standards, UL listings and the manufacturer's data. Test criteria, developed by third party agencies such as UL provides the consumer with independent documentation on product performance characteristics. Approval agencies such as UL assure the products meet a minimum performance requirement.
Independent tests provide non-biased evaluation and information for product comparisons.
This information can be used as a pre-purchase comparison and can also be used to compose a purchasing specifications that will assure minimum performance and suitability for an intended use. The test consists of a 50 Sq. The test fuel is ignited and allowed to preburn for 1 minute before application of foam has begun. The fire must be completely extinguished during or by the end of the foam discharge. The foam blanket must remain undisturbed for a period of 15 minutes after discharge is terminated.
