1 Proposed revision of BHMA A AMERICAN NATIONAL STANDARD FOR DOOR GASKETING and EDGE SEAL SYSTEMS SPONSOR BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. Revision C June 2, 2016 Revision D June 29, 2016 Revision E August 24, 2016 Received August 24, 2016 for review at the next meeting: Just a note on something for clarification at the next meeting. We ran out of time at the last meeting for me to bring it up. We have a Rating chart in paragraph 10.6 that refers back to paragraphs 5.3 and 5.4 for Smoke or Energy performance. The chart utilizes Ratings 0 thru 7. The Heat and Cold tests in paragraphs 6.2 and 6.3 also reference a Rating of 4 or 5 or 6. Although it makes sense that there is a relationship between temperature and smoke/energy ratings (smoke test per UL1784 requires the elevated temperature test which is run at 400 F), I think there might be a disconnect now. In short, because of the added ratings in the chart in paragraph 10.6, should we add a clarification note in the heat/cold testing to include something about Ratings 0,1,2,3, and 7? The Heat test requires the gasket to withstand the 400 F temp for 168 hours. The elevated Smoke test from UL1784 only requires the gasket to withstand the 400 F temp for minutes. So, is the standard requiring any gasket that is to be Smoke rated to also HAVE to pass the full Heat test? If not, we should use a different Rating for the Heat and Cold tests. Regards, Mark A. McRae Director of Engineering 1

3 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.22) The general classification of builders hardware includes a wide variety of items which are divided into several categories. To recognize this diversity, a sectional classification system has been established. Door Gasketing Systems is one such sub section and this Standard is a result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc. who manufacture this product. The total Product Standards effort is, therefore, a collection of sections, each covering a specific category of items. Performance tests have been established to ensure safety and stability to which the public is entitled. There are no restrictions on design. This Standard is not intended to obstruct but rather to encourage the development of improved products, methods and materials. The BHMA recognizes that errors will be found, items will become obsolete, and new products, methods and materials will be developed. With this in mind, the Association plans to update, correct and revise these Standards on a regular basis. It shall also be the responsibility of manufacturers to request such appropriate revisions. The BHMA numbers which indicate functions of gasketing do not identify size or design and are not intended to be used without necessary supplementary information. Individual manufacturer's catalogs are to be consulted. 3

This isn t a covered by the BHMA standard and is touched on in the appendix. Some of the parts in these paragraphs state some with and others state it as a blanket statement, which may or may not be correct. A-10 Suggest removing this paragraph. What is the intent? A-11 Suggest removing this paragraph as it is no longer relevant. A-14 Remove first sentence. Suggest moving second sentence in this paragraph into 4.1 as it is part of the test set up for pairs.

22 APPENDIX A USERS GUIDE (Not part of ANSI/BHMA A152.22) A-1 Because of environmental conditions, doors and frames are not completely stable in all uses. For this reason, gasketing frequently has adjustable attributes. This adjustability is accomplished with slotted installation holes or other compensating means. A-1.1 These features in A-1 permit the opportunity to seriously inhibit the closing and latching of doors by over compression. The field installer therefore weighs the relative merits of sealing vs. proper door function and adjusts the system in accordance with Section 5 of this Standard. A-1.2 Clearances between the door and frame especially on the hinge side vary with different door manufacturers. When clearances of 1/16 in (1.6 mm) or less are encountered, care is taken as to the type of gasketing to use as some products exceed this dimension even after compression and the force to close the door in such installations is in excess of a 50 lbf (447 N). A-2 When the meeting edges of a pair of doors are gasketed, requirements in the ANSI/NFPA 101 Life Safety Code and the model building codes are observed. For pairs of doors within a means of egress, codes frequently prohibit the use of devices which depend upon the opening of one door before the other is able to be opened. This often requires the use of astragals other than overlapping astragals. Such astragals are commonly supplied in flat, tee, split and adjustable styles with or without gasketing elements. Care must be taken when specifying astragals as many factors must be considered. Standards such as NFPA 80, Fire Doors and Windows, NFPA 101, Life Safety Code, NFPA 105, Smoke Control Doors and Local Building Code should be consulted. Local authorities having jurisdiction should be consulted if there is any question. Fire Doors having labels that state: When used in pairs an astragal is required can only be satisfied with the one approved in the limitations of the door listing. Fire Doors not specifying this requirement may use approved astragal(s) that satisfy the need to prevent the transfer of air, smoke, sound, light, moisture, etc. Their removal, omission, or substitution may violate the listing. A-3 The force to close a door can be measured in a variety of ways. The method described in 5.1 is the same method used in other ANSI/BHMA Standards. It does not take into account the velocity of a closing door under the control of a door closer. The value of a 10 lbf (44 N) was selected to recognize this factor. A-4 Users of this Standard note that thresholds with integral gasketing are included in ANSI/BHMA A for Thresholds and are not included in this Standard. A-5 Conformance Criteria. Certification that products offered meet the requirements of this Standard and conform to individual manufacturer's specifications, standards, and quality assurance practices are available and in some circumstances are required. Buyer requirements determine the need for proof of conformance such as first article inspection, test laboratory reports or listings. Specifiers requiring assertions of conformance utilize statements of conformance furnished by individual manufacturers, or test reports acceptable to the buyer. You can also go to the BHMA website at to view the Certified Products Directory on-line. 22

23 A-6 Preservation, Packaging, and Packing. Unless other arrangements between buyer and seller are made, preservation, packaging, and packing shall be sufficient to protect containers and their contents under normal shipping and handling conditions from the source of supply to the destination point. A-7 Marking. Unless other arrangements between buyer and seller are made, marking shall be in accordance with the individual manufacturer's standard practice. A-8 Kerf Gasket Installation. Kerf gasketing is provided with a range of compressibility determined and specified by the manufacturer. It is important to ensure the installation including the gasketing maintains the door/latchbolt/strike/stop relationships specified by the door and hardware manufacturers. Altering of latchbolts is never permitted. Malfunctions may result including trapping the deadlocking latchbolt in the strike. A-9 Meeting the leakage requirement is generally more difficult on smaller doors than larger doors of similar design due to the area to perimeter ratio. For example, the area of a 3x7 ft door is 21 sq.ft. with a perimeter of 20 ft., compared to a 4x8 ft. door having an area of 32 sq. ft. and a perimeter of 24 ft. A-10 Where required by Building Codes, gasketing shall be marked as specified by a nationally recognized testing laboratory. A-11 Refer to ANSI/SDI A250.6 Hardware on Standard Steel Doors or NAAMM/HMMA Guide Specification for Installation and Storage of Hollow Metal Doors and Frames for installation information. A-12 Ref 5.3 Smoke Infiltration Test. Although the standard literally states tested for inhibition of the passage of smoke, the approved test method of UL 1784 uses air, not smoke, for the smoke rating. 23
