UL 199:2020 pdf download.STANDARD FOR SAFETY--Automatic Sprinklers for Fire-Protection Service
1.1 These requirements cover automatic sprinklers including conventional, spray, sidewall, extended coverage, residential, certain specific application sprinklers and storage sprinklers including early suppression fast response (ES FR) intended for installation on sprinkler systems for fire-protection service. Requirements for the installation and use of sprinklers are included in the Standards for the Installation of Sprinkler Systems, NFPA 13; Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, NFPA 13D; and Installation of Sprinkler Systems in Low-Rise Residential Occupancies, NFPA 1 3R; as well as other applicable NFPA Standards.
1.2 The requirements in this standard are not intended to restrict the application of representative fire and other tests for special sprinklers, as referenced in Standard for the Installation of Sprinkler Systems, NFPA 13, that are intended to provide protection for specific fire hazards.
2 Components
2.1 Except as indicated in 2.2, a component of a product covered by this standard shall comply with the
requirements for that component.
2.2 A component is not required to comply with a specific requirement that:
a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or
b) Is superseded by a requirement in this standard.
2.3 A component shall be used in accordance with its rating established for the intended conditions of use.
2.4 Specific components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions.
3 Units of Measurements
3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or
approximate information.
4 Undated References
4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard.
5 Glossary
5.1 For the purpose of this standard the following definitions apply:
5.2 ACTUAL DELIVERED DENSITY (ADD) — The rate at which water, discharged from a sprinkler, is actually deposited onto the top of the protected horizontal surface under a fire condition.
5.3 ASSEMBLY LOAD — The extension force applied to the sprinkler frame by the assembly of its operating mechanism.
5.4 AUTOMATIC SPRINKLER — A sprinkler intended to open automatically by operation of a heat- responsive element that maintains the discharge orifice closed by means such as the exertion of pressure on a cap (button or disc). A sprinkler is installed on piping so that a spray of water is discharged in a specific pattern for suppression or control of fires.
5.5 CEILING SPRINKLER — See Concealed Ceiling Sprinkler (5.7), Flush Ceiling Sprinkler (5.18) and Recessed Ceiling Sprinkler (5.28).
5.6 COATED, PAINTED, OR PLATED SPRINKLER — A sprinkler that has factory applied coatings, paint, or platings for corrosion protection or decorative purposes.
5.7 CONCEALED CEILING SPRINKLER — A sprinkler assembly having a cover plate.
5.8 CONTROL MODE DENSITY AREA (CMDA) STORAGE SPRINKLER FOR STANDARD COVERAGE AREAS — A sprinkler intended to be installed using standard coverage areas and density/area criteria referenced in NFPA 13.UL 199 pdf download.
