General Notes

Materials: For doors and frames – commercial quality, level, cold-rolledsteel conforming to ASTM A 1008/A 1008M or hot-rolled, pickled andoiled steel conforming to ASTM A 1011/A 1011M or stainless steelconforming to ASTM A 666, Type 304 or 316. Material thicknesseslisted in chart are minimums. Where recommended in the guide speci-fications, use zinc-coated steel conforming to ASTM A 653 / A 653M.

Testing and Performance: HMMA 861 requires the following test:Performance Test for Steel Doors and Hardware Reinforcings (ANSIA250.4). HMMA 862 incorporates testing procedures and perfor-mance requirements promulgated by NILECJ for class IV doors (ASTMF 476) including Jamb/Wall Stiffness Performance, Door Impact Test,Door and Glazing Panel Impact Resistance Performance, (new test)and SD-STD-01.01 (Rev G) or LPS 1175: Issue 5 standards for ForcedEntry and Ballistic Resistance Testing. HMMA 863 requires thefollowing tests: Static Load test; Rack test; Impact test; Edge Crush test;Side-light frame test; and multiple light frame test under ASTM F 1450and F 1592. Bullet Resistance testing, where applicable, is performedin accordance with UL-752. Manufacturers must submit independentlaboratory reports certifying performance required by these tests onsample doors and frames as specified in the standards. HMMA 867requires the following test: Performance Test for Steel Doors and Hard-ware Reinforcings (ANSI A250.4).

(10) Frames for installation in masonry walls provided with adjustablejamb anchors of T-strap or wire type. Straps not less than 2"X10"in size.

(11) Frames for installation in masonry walls provided with adjustablejamb anchors of strap and stirrup type. Straps not less than2"X10" in size.

(12) Provided at all hardware mortises on frames that are specified tobe grouted.

(13) Interior frames may be provided with snap-on glazing stops.

(14) Where shown in non-security locations, 0.067 in. (1.7mm, 14ga.) pressed steel channel provided.

The Hollow Metal ManualThe Hollow Metal Manual is presented in 14 separate, saddle-stitchedsections in an attractive three-ring binder. The Manual provides designprofessionals the most current information on manufacturing, door andframe designs and details, hardware preparation and location, instal-lation and storage, fire-rated applications, common terms, plus theguide specifications.

The Hollow Metal Manufacturers Association (HMMA) Division ofNAAMM, the National Association of Architectural Metal Manufac-turers, publishes the Hollow Metal Manual to aid building designprofessionals in specifying hollow metal.

The HMMA guide specifications cover a broad range of door andframe applications. HMMA 860 addresses doors and frames for lighttraffic areas.
