90B- Log #2 NFPA 90B Arthur Londensky, Northeastern Regional Fire Code Development Committee Revise text to read as follows: This standard shall apply to all systems for the movement of environmental air in structures that serve the following: 1.3.1 This standard shall apply to all systems for the movement of environmental air in structures that serve the following: (1) One- or two-family dwellings (2) Spaces not exceeding 708 m 3 (25,000 ft 3 ) in volume in any occupancy (3) Buildings of combustible construction over three stories in height shall be in accordance with. 1.3.2 This standard shall not apply to systems for the movement of environmental air in buildings of combustible construction over three stories in height. Currently 1.3 (3) denotes a condition where the Standard does not apply in a paragraph that indicates where the Standard does apply. It seems clearer to create another paragraph that describes where the Standard does not apply. 90B- Log #9 Marcelo M. Hirschler, GBH International Update ASTM publications to read: ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750 C,2006 2011. ASTM E2652, Standard Test Method for Behavior of Materials in a Tube Furnace with a Cone-shaped Airflow Stabilizer, at 750 C,(2009a) This change puts NFPA 90B in line with what was done for NFPA 101 (and many other documents) in the 2012 cycle. NFPA requirements are that definitions cannot contain requirements and the definitions of noncombustible and limited combustible contain requirements. Therefore this public input proposes to put simply a place holder in chapter 3 (definitions) and place the requirements into Chapter 4, just as was done in NFPA 101 and 5000. The proposed language is identical to the language in NFPA 101. If the technical committee wishes it can simply extract the language from NFPA 101. The corresponding sections are: 3.3.8 would be extracted from 3.3.169.4 and 4.1 would be extracted from 4.6.13. 90B- Log #4 John F.

90B- Log #6 NFPA 90B Marcelo M. Hirschler, GBH International Revise text to read: See 4.1 A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release flammable vapors when subjected to fire or heat. Materials that are reported as passing ASTM E 136,, are considered noncombustible materials. This change puts NFPA 90B in line with what was done for NFPA 101 (and many other documents) in the 2012 cycle.

American Fire Safety Council Revise text to read as follows: A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release flammable vapors, when subjected to fire or heat. [101, 2012] Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750 Degrees C, shall be considered noncombustible materials.[220, 2009] A material that is reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750 Degrees C, is considered a noncombustible material. A material that is reported as complying with the pass/fail criteria of ASTM E 136 when tested in accordance with the test method and procedure in ASTM E 2652, Standard Test Method for Behavior of Materials in a Tube Furnace with a Cone-shaped Airflow Stabilizer, at 750 Degrees C, is considered a noncombustible material. The definition of noncombustible material has been amended in NFPA 101 and 5000 to eliminate the second sentence with the requirements. 2

90B- Log #7 NFPA 90B Marcelo M. Hirschler, GBH International Add a new section to read: A material that complies with any of the following shall be considered a noncombustible material: (1)* A material that, in the form in which it is used and under the conditions anticipated, will not ignite, burn, support combustion, or release flammable vapors when subjected to fire or heat (2) A material that is reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750 Degrees C (3) A material that is reported as complying with the pass/fail criteria of ASTM E 136 when tested in accordance with the test method and procedure in ASTM E 2652, Standard Test Method for Behavior of Materials in a Tube Furnace with a Cone-shaped Airflow Stabilizer, at 750 Degrees C This change puts NFPA 90B in line with what was done for NFPA 101 (and many other documents) in the 2012 cycle.

Hirschler, GBH International Renumber sections 4.1 through 4.3 as 4.2 through 4.4. This change puts NFPA 90B in line with what was done for NFPA 101 (and many other documents) in the 2012 cycle. NFPA requirements are that definitions cannot contain requirements and the definitions of noncombustible and limited combustible contain requirements. Therefore this public input proposes to put simply a place holder in chapter 3 (definitions) and place the requirements into Chapter 4, just as was done in NFPA 101 and 5000.

90B- Log #12 NFPA 90B Marcelo M. Hirschler, GBH International Revise text to read: 4.1.1.1.3.1 The connector shall be made of approved fabric meeting the flame propagation performance criteria contained in Test Method 1 or Test Method 2, as appropriate, of NFPA 701 and shall not exceed 254 mm (10 in.) in length in the direction of airflow. In 1989 the NFPA Technical Committee on Fire Tests eliminated the so-called small-scale test from NFPA 701 because the results had been shown not to represent a fire performance that corresponded to what happened in real scale. Instead of the small-scale test NFPA 701 now (and for over 20 years) contains two tests (Test 1 and Test 2), which apply to materials as indicated by the text of NFPA 701 (2010) that is shown at the bottom of this public input. However, a large number of manufacturers continue stating that the materials or products that they sell have been tested to NFPA 701, when they really mean the pre-1989 small-scale test in NFPA 701. That test no longer exists and materials or products meeting that test do not exhibit acceptable fire performance. Text of NFPA 701 (2010): 1.1.1.1 Test Method 1 shall apply to fabrics or other materials used in curtains, draperies, or other window treatments. Vinyl-coated fabric blackout linings shall be tested according to Test Method 2. 1.1.1.2 Test Method 1 shall apply to single-layer fabrics and to multilayer curtain and drapery assemblies in which the layers are fastened together by sewing or other means. Vinyl-coated fabric blackout linings shall be tested according to Test Method 2. 1.1.1.3 Test Method 1 shall apply to specimens having an areal density less than or equal to 700 g/m2 (21 oz/yd 2 ), except where Test Method 2 is required to be used by 1.1.2. 1.1.2.1 Test Method 2 (flat specimen configuration) shall be used for fabrics, including multilayered fabrics, films, and plastic blinds, with or without reinforcement or backing, with areal densities greater than 700 g/m2 (21 oz/yd 2 ). 1.1.2.2 Test Method 2 shall be used for testing vinyl-coated fabric blackout linings and lined draperies using a vinyl-coated fabric blackout lining. 1.1.2.3 Test Method 2 shall be used for testing plastic films, with or without reinforcement or backing, when used for decorative or other purposes inside a building or as temporary or permanent enclosures for buildings under construction. 1.1.2.4 Test Method 2 shall apply to fabrics used in the assembly of awnings, tents, tarps, and similar architectural fabric structures and banners. Note also the following from the text of NFPA 701 (2010): 1.2* Purpose. 1.2.1 The purpose of Test Methods 1 and 2 shall be to assess the propagation of flame beyond the area exposed to the ignition source. A.1.1 A small-scale test method appeared in NFPA 701 until the 1989 edition. It was eliminated from the test method because it has been shown that materials that pass the test do not necessarily exhibit a fire performance that is acceptable. The test was not reproducible for many types of fabrics and could not predict actual full-scale performance. It should not, therefore, be used. A.1.1.1 For the purposes of Test Method 1, the terms curtains, draperies, or other types of window treatments, where used, should include, but not be limited to, the following items: (1) Window curtains (2) Stage or theater curtains (3) Vertical folding shades (4) Roll-type window shades (5) Hospital privacy curtains (6) Window draperies ) Fabric shades or blinds (8) Polyvinyl chloride blinds (9) Horizontal folding shades (10) Swags Examples of textile items other than window treatments to which Test Method 1 applies include: (1) Table skirts 4

NFPA 90B (2) Table linens (3) Display booth separators (4) Textile wall hangings (5) Decorative event tent linings not used in the assembly of a tent Note that this change was already approved by NFPA FUR for NFPA 101 and NFPA 5000 and was also approved for the IBC. 5

90B- Log #11 NFPA 90B Marcelo M. Hirschler, GBH International Revise text to read: 4.3.2.4.1 Tape, where exposed to the air in the system, shall not be more combustible than fabric complying with the flame propagation performance criteria contained in Test Method 1 or Test Method 2, as appropriate, of NFPA 701. In 1989 the NFPA Technical Committee on Fire Tests eliminated the so-called small-scale test from NFPA 701 because the results had been shown not to represent a fire performance that corresponded to what happened in real scale. Instead of the small-scale test NFPA 701 now (and for over 20 years) contains two tests (Test 1 and Test 2), which apply to materials as indicated by the text of NFPA 701 (2010) that is shown at the bottom of this public input. However, a large number of manufacturers continue stating that the materials or products that they sell have been tested to NFPA 701, when they really mean the pre-1989 small-scale test in NFPA 701. That test no longer exists and materials or products meeting that test do not exhibit acceptable fire performance. Text of NFPA 701 (2010): 1.1.1.1 Test Method 1 shall apply to fabrics or other materials used in curtains, draperies, or other window treatments. Vinyl-coated fabric blackout linings shall be tested according to Test Method 2. 1.1.1.2 Test Method 1 shall apply to single-layer fabrics and to multilayer curtain and drapery assemblies in which the layers are fastened together by sewing or other means. Vinyl-coated fabric blackout linings shall be tested according to Test Method 2. 1.1.1.3 Test Method 1 shall apply to specimens having an areal density less than or equal to 700 g/m2 (21 oz/yd 2 ), except where Test Method 2 is required to be used by 1.1.2. 1.1.2.1 Test Method 2 (flat specimen configuration) shall be used for fabrics, including multilayered fabrics, films, and plastic blinds, with or without reinforcement or backing, with areal densities greater than 700 g/m2 (21 oz/yd 2 ). 1.1.2.2 Test Method 2 shall be used for testing vinyl-coated fabric blackout linings and lined draperies using a vinyl-coated fabric blackout lining. 1.1.2.3 Test Method 2 shall be used for testing plastic films, with or without reinforcement or backing, when used for decorative or other purposes inside a building or as temporary or permanent enclosures for buildings under construction. 1.1.2.4 Test Method 2 shall apply to fabrics used in the assembly of awnings, tents, tarps, and similar architectural fabric structures and banners. Note also the following from the text of NFPA 701 (2010): 1.2* Purpose. 1.2.1 The purpose of Test Methods 1 and 2 shall be to assess the propagation of flame beyond the area exposed to the ignition source. A.1.1 A small-scale test method appeared in NFPA 701 until the 1989 edition. It was eliminated from the test method because it has been shown that materials that pass the test do not necessarily exhibit a fire performance that is acceptable. The test was not reproducible for many types of fabrics and could not predict actual full-scale performance. It should not, therefore, be used. A.1.1.1 For the purposes of Test Method 1, the terms curtains, draperies, or other types of window treatments, where used, should include, but not be limited to, the following items: (1) Window curtains (2) Stage or theater curtains (3) Vertical folding shades (4) Roll-type window shades (5) Hospital privacy curtains (6) Window draperies ) Fabric shades or blinds (8) Polyvinyl chloride blinds (9) Horizontal folding shades (10) Swags Examples of textile items other than window treatments to which Test Method 1 applies include: (1) Table skirts (2) Table linens 6

Since cable routing assemblies, unlike raceways, are not required to be enclosed, the cables in a cable routing assembly may be exposed to the airflow and therefore must be listed for use in a plenum. The recommended additional last sentence therefore requires plenum grade cables in signaling, optical fiber and communications raceways and in cable routing assemblies installed in ceiling cavity plenums.
