Horizontal Burn Test ASTM

The sample material is tested in air in the form of strips held with their longitudinal axis horizontal and their transverse axis at 45° to the horizontal. The sample is ignited at one end with a Tirrell burner and the rate and extent of burning is reported. [Pg.267]

This measures the susceptibility of a material to be ignited by an external flame and when exposed to a radiant heat source. The radiant energy is applied from a conical heater, thus giving a uniform heat flux over the sample. The severity of the test can be varied by varying the energy output from the radiant heater. [Pg.267]

The pyrolysis gases are allowed to build up in the cone heater and a small pilot flame is intermittently applied. The time to ignition is determined visually and quoted together with the heat output of the radiant heater. [Pg.267]


The UL 94 standard specihes bench-scale test methods to determine the acceptability of plastic materials for use in appliances or other devices with respect to flammability under controlled laboratory conditions. The test method that is used depends on the intended end-use of the material and its orientation in the device. The standard outlines two horizontal burning tests, three vertical burning tests, and a radiant panel flame spread test. The most commonly used test method described in the UL 94 standard is the 20-mm Vertical Burning Test V-0, V-l, or V-2. The method is also described in ASTM D 3801. A schematic of the test setup is shown in Figure 14.3. [Pg.355]

These two tests are similar to those defined in BS 2782, Part 1, Method 140A (20). This test is similar to the UL94 [21] Vertical burning (UL94, VO, VI. V2) and horizontal burn tests (UL94HB). The horizontal test is similar to ASTM D635 [22], while the vertical test is defined in ASTM D3801 [23]. [Pg.669]

ASTM D635, Test Methodfor Rate ofBurning and/ or Extent and Time of Burning of Sef-SupportingPlastics in a Horizontal Position, Vol. 8.01, ASTM, Philadelphia, Pa., 1991. [Pg.160]

The ASTM fire test procedure describes a small-scale laboratory determination of the relative linear rate of burning of plastics and plastic-based composites. Specimens can be in the form of bars, molded or cut from sheets, plates, or panels and tested in the horizontal position. The results of the test are intended to serve as a preliminary indication to their flammability. [Pg.478]

ASTM D635-91, "Test Method for Rate of Burning andlor Extent of Burning of self-supporting Plastics in a Horizontal Position," Philadelphia (1991). [Pg.931]

ASTM D 470-81 uses the same test chamber with a 254 mm long piece of wire mounted horizontally between two clamps at 203 mm from one another. The wire is ignited by a 102 to 127 mm long flame for 30 s. Cotton wool is placed 240 mm below the ignition point. The length and duration of burning is observed and it is recorded whether the cotton has flared up. [Pg.228]

ASTM D635 (2010) Standard Test Method for Rate of Burning and/or Extent and Times of Burning of Plastics in a Horizontal Position. [Pg.137]

ANSI/ASTM E 84-79a - method of test for surface burning characteristics of building materials (Steiner tunnel). A 24-foot-long specimen is held horizontally as the roof of a 25-foot-long chamber. The ignition source is two gas burners, applied to the underside of one end. Flame spread is measured visually and instruments are used to determine fuel contribution and smoke density. The test is identical with UL 723 and ULC-S 102 1978, used in Canadian Building Regulations. [Pg.290]
