What is the methenamine pill test?
ASTM D2859 or the methenamine pill test, is also called the Standard Method for Ignition Characteristics of Finished Textile Floor Covering Materials. This pass/fail test measures the size of the burn to determine flame resistance of textile floor coverings.
What is doc FF 1 pill test?
The most common testing methods for small carpets/rugs are DOC FF1-70, commonly called the “pill test,” and DOC FF2-70. With DOC FF1-70, eight 9″ x 9″ specimens are tested. A hole is cut in each one and a tablet (often referred to as a pill) is placed on the mat and ignited.
What is the radiant panel test?
The flooring radiant panel test evaluates the propensity of a floor system to spread fire when exposed to intense radiant heat from a gas-fired radiant panel. Specifically, the method determines the minimum level of heat energy required to sustain the burning of a material.
What is ASTM e84?
ASTM E 84. Standard test method for surface burning characteristics of of building materials. The flame spread Index and Smoke Developed Index values obtained by the ASTM E 84. test are used by code officials and regulatory agencies in the acceptance of interior finish. materials for various applications.
What is the room corner test?
Room Corner Test to perform fire reaction tests simulates a fire in a well-ventilated conditions started in a corner of a small room with one door open according to the standard ISO 9705:1993. It is intended to evaluate the contribution to fire growth provided by a product surface using a specified ignition source.
What is the vertical flame test?
A test specimen is positioned vertically above a controlled flame and exposed for a specified period of time. Following exposure, the flame source is removed. Measurements are made on the length of time that the specimen continues to flame and the time afterglow continues after the flame source has been removed.
What does a flame spread of 25 mean?
A numerical reference that measures how fast and far a flame spreads during a 10-minute test. CLASS A = Flame Spread Index of 25 or less; the best possible rating, awarded to fire-retardant building products, like concrete.
What does ASTM E84 test?
The ASTM E-84 is the standard test method for assessing the surface burning characteristics of building products to explore how the material might contribute to flame spread in the event of a fire. The test reports the Flame Spread index and Smoke Developed index of the tested product.
What NFPA 253?
NFPA 253: Standard Method of Test for Critical Radiant Flux of Floor Covering Systems Using a Radiant Heat Energy Source.
Is a lower flame spread better?
Flame Spread results range on an index from Class A (the best) to lower classes.
What is a Class C flame spread?
A Class C or Class 3 fire rating has a flame spread rating between 76 and 200. This rating incorporates building materials like plywood, fiberboard, and hardboard siding panels. It also includes any of the faster burning whole woods.
What NFPA 255?
NFPA 255: Standard Method of Test of Surface Burning Characteristics of Building Materials.
