Fire Codes - Common Test Procedures & Testing

How They Are Determined:

Established at all levels, fire codes government, building materials, stationary and decorative items have been developed. Depending on intended use; materials must pass specific tests in order to meet fire safety codes and regulations. Codes are written and implemented and accredited testing laboratories evaluate submitted specimens and according to the test criteria that has been requested the most appropriate testing is performed for that particular product or item. Generally, standard testing consists of measuring smoke and flame spread, developed both vertically and horizontally, under conditions simulating their actual use, For example, the Steiner Tunnel test (ASTM E-84/NFPA 255/UL 723) is used to measure flame spread in horizontal positions, such as carpeting, flooring, etc. The NFPA-701 Test measures flame spread vertically for such items as draperies, decorative hangings, etc.

What is Considered A Class "A" Fire retardant?

The American Society for Testing and Materials (ASTM) and the National Fire Protection Association (NFPA) are the two nationally recognized Organizations, which have developed tests setting standard of flammability. On a scale of 0-200 (least to most), only those materials with a flame spread of less than 25 feet qualify as a Class "A" Fire retardant by ASTM E-84 and NFPA rates the product or item as NFPA 2 Hour.

Test Method

The flame spread results of 25 foot tunnel test are frequently used by building code officials and regulatory agencies in the acceptance of interior finish material for various applications. The most widely accepted classification system is epitomized by the National Fire Protection Association Life Safety Code, NFPA No. 101:

A - NFPA 2 Hour                   I                                   0 through 25
B - NFPA 1 Hour II 26 through 75
C III 76 through 200
D IV 201 through 500
E V Over 500


Delta Pacific Technologies, Inc. believes that testing of a product, particularly a fire retardant product, is necessary in order to screen and eliminate those products that may find their way to the market-place with claims that do not support safety and performance, from the products that have been properly tested and have been approved. When acceptable testing is done through several larger laboratories and independent as well, throughout the United States, it allows government agencies, fire and building officials and regulatory agencies the assurance through this testing process and certification, that they can accept, and specify the approved product and know that it will meet their code requirements.

Listed below are some definitions and comparisons which will help you understand and become knowledgeable on testing, classification, and certification of various products and items.
