۲۰۱۶ Edition
Chapter 1 Administration
۱-۱ Scope.
۱-۱-۱ This standard covers the minimum requirements for the installation of standpipes and hose systems.
۱-۱-۲* This standard does not cover requirements for periodic inspection, testing, and maintenance of these systems.
۱-۲ Purpose.
۱-۲-۱ The purpose of this standard is to provide a reasonable degree of protection for life and property from fire through installation requirements for standpipes and hose systems based on sound engineering principles, test data, and field experience.
۱-۲-۲ Nothing in this standard is intended to restrict new technologies or alternate arrangements, provided that the level of safety prescribed by the standard is not lowered.
۱-۳ Retroactivity. The provisions of this standard reflect a consensus of what is necessary to provide an acceptable degree of protection from the hazards addressed in this standard at the time the standard was issued.
۱-۳-۱ Unless otherwise specified, the provisions of this standard shall not apply to facilities, equipment, structures, or installations that existed or were approved for construction or installation prior to the effective date of the standard. Where specified, the provisions of this standard shall be retroactive.
۱-۳-۲ In those cases where the authority having jurisdiction determines that the existing situation presents an unacceptable degree of risk, the authority having jurisdiction shall be permitted to apply retroactively any portions of this standard deemed appropriate.
۱-۳-۳ The retroactive requirements of this standard shall be permitted to be modified if their application clearly would be impractical in the judgment of the authority having jurisdiction, and only where it is clearly evident that a reasonable degree of safety is provided.
۱-۴* Equivalency. Nothing in this standard is intended to prevent the use of systems, methods, or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety over those prescribed by this standard.
۱-۴-۱ Technical documentation shall be submitted to the authority having jurisdiction to demonstrate equivalency.
۱-۴-۲ The system, method, or device shall be approved for the intended purpose by the authority having jurisdiction.
۱-۵ Units.
۱-۵-۱ Metric units of measurement in this standard are in accordance with the modernized metric system known as the International System of Units (SI). Liter and bar units, which are outside of but recognized by SI, are commonly used in international fire protection. These units and their conversion factors are provided in Table 1.5.1.
۱-۵-۲ If a value for measurement provided in this standard is followed by an equivalent value in other units, the first value stated shall be regarded as the requirement. An equivalent value could be approximate.
