ANSI/BHMA A156.4-2000 pdf free download.Door Controls – Closers.
1. SCOPE
1.1 ANSI/BHMA A156.4-2000 contains requirements for door closers surface mounted, concealed in the door, overhead concealed and concealed in the floor. Also included are pivots for floor closers. Criteria for conformance include cycle, operational, closing force and finish tests. Optional tests which shall be specified separately are also included.
1.2 Tests in this Standard are performed under laboratory conditions. In actual usage results vary because of installation, maintenance, and environmental conditions.
1.3 Use on Fire Doors. A door closer used on labeled fire door assemblies shall be listed or labeled by a nationally recognized independent testing laboratory, and be subject to a periodic in-plant follow-up service. Consult the authority having jurisdiction for the appropriate fire test requirements.
2. GENERAL
2.1 Reference to other Standards. ANSi Standards referenced in this Standard are available from the American National Standards Institute, 11 West 42nd Street, New York, NY 10036.
2.2 Type Numbers. This Standard has been prepared to standardize door closers and controls by type requirements and performance levels. Only those type numbers shown in this Standard shall be used. For explanation of identifying numbers, see 11.13.
2.3 Manufacturer’s Catalogs. Consult manufacturer’s catalogs for construction details and special conditions relating to accessories.
2.4 Tolerances. All values which do not carry specific tolerances or are not marked maximum or minimum shall have the following tolerances: Number of cycles shall be minimum. Linear dimensions shall be ± 1/16 in. (1.6 mm). Pounds or pound force shall be ± 2%. The scribed lines for degree of opening shall be ±2 degrees.
2.5 SI Units. All dimensions are expressed first in US units with SI unit (metric) equivalents given in parentheses. SI units are approximate.
3. PERFORMANCE TEST REQUIREMENTS (For a Summary of Test Requirements See Table A2)
3.1 All Closers. Door closers shall be categorized as listed in the following groupings by their performance requirements.
3.2 Fluid. Fluid used in door closers intended for exterior or vestibule door application shall have a pour point of minus 38 degrees F (-39 degrees C) or lower when tested in accordance with ASTM D-97.
3.3 Templating. Test templating shall be in accordance with paragraph 4.2.4.
3.4 Types to Test. Non-hold open type closers shall be used for all testing.
3.5 PT 1 – Test for Grade 1 Surface or Concealed in Door Closers
3.5.1 Door shall be under control from 115 degrees of door opening to the closed position (6.1).
4.2 The Door Closer
4.2.1 A manufacturer’s stock door closer shall be used for testing. For surface mounted and concealed in door closets, a size IV closer shall be used for qualification purposes. For floor and overhead concealed closets, a size III or IV closer shall be used for qualification purposes. The manufacturer shall certify that the balance of the line also meets the performance requirements.
4.2.2 If door closer bodies of the same type are of substantially the same construction, the cycle test (6.6) shall be required only for one arm application (i.e. hinge side, parallel arm, track arm, bracket mounting or top jamb mounting) under tests PT 1, PT 2, and PT 3. All other tests (6.1 through 6.7) as applicable, shall be required for all arm applications.
4.2.3 Only one door closer shall be used for all three phases of the test series, and shall be run consecutively. (5.1, 5.2, and 5.3).
4.2.4 The door closer shall be installed in accordance with the manufacturer’s instructions for 90 degrees of door opening. (Except in the case of 3.5.1, after the control test, closer shall be remounted for 90 degrees of door opening.)
