ASME A17.1-2010 pdf download.Safety Code for Elevators and Escalators.
1.2.1 Purpose The requirement was introduced in ASME A17.1-2007/CSA B44-07. It is a major departure from past code requirements that only recognized compliance with the requirement stated in the ASME A17.1/ CSA B44 Code. If you did not comply an exception (variance) from an AHJ was required. Now the code formally recognizes compliance with the Performance Based Safety Code for Elevators and Escalators, ASME A17.7/CSA B44.7 as being equivalent to meeting the requirements in the ASME A17.1/ CSA B44 Code. In other words a new or innovative product that cannot comply with a requirement(s) in ASME A17.1/CSA B44 but does satisfy ASME A17.7/ CSA B44.7 is considered compliant with ASME A17.1/ CSA B44. Alternatively the AHJ could be asked to grant an exemption from the requirement(s) in ASME A17.1/ CSAB44utilizingthe procedures in1.2.2. The ASME A17 and CSA B44 Committee still envision the use of Excep- tion (1.2.2) for one of a kind and unique applications. However, for innovative new technology the A17.7/ B44.7 Code should be utilized. The ASME A17.7/CSA B44.7 Code provides a struc- tured approach for introducing new technology prod- ucts to the marketplace. The approachis based on Global Essential Safety Requirements (GESRs) that have to be satisfied and a risk assessment process to ensure GESRs are met. An Accredited Elevator/Escalator Certification Organization(AECO),inconjunctionwithanequipment designer, will examine the process and provide docu- mentation. The AECO is responsible for certifying design compliance with ASME A17.7/CSA B44.7.
This Section defines the terms used in the Code. These may be words with unique meanings when used in the context of elevators. For example, the word “safety” is used as a noun to identify a device for stopping and holding the elevator in the event of overspeed. The user of the Code should become familiar with all terms con- tained in Section 1.3. Where terms are not defined, they have ordinarily accepted meanings or application as the context may imply. Words used in the present tense may also include the future. Words in the masculine gender include the feminine and neuter. Words in the feminine and neuter gender include the masculine. The singular number may also include the plural and the plural number includes the singular. Many interpretation requests can be avoided if time is taken to become familiar with the definitions in this Section. Performance terminology: Industry standards for dimensional, performance, application, electrical, and evaluation of building transportation equipment are published in NEII-1, Building Transportation Standards and Guidelines. Performance terms are defined and mea- surement standards specified. NEII-1 incorporates the Code requirements in ASME A17.1/CSA B44, NFPA 70, etc. It is an invaluable reference for architects, engineers, consultants, building owners and managers, elevator manufacturers, contrac- tors,andsuppliers. NEII-1 canbefoundatwww.neii.org. Access to NEII-1 is available at no cost.
The Uniform Building Code (UBC) began publishing in the late 1920s. It was developed and published by the International Conference of Building Officials (ICBO) and was widely adopted west of the Mississippi River. In the spring of 2000, the three U.S. model building codes collaborated to publish the International Building Code (IBC), whichwaspromulgatedbythe International Code Council (ICC). The IBC has replaced the model codes previously mentioned in the last few years. In 2003, the National Fire Protection Association published the Building Construction and Safety Code, NFPA 5000. To date, no major United States or Canadian jurisdiction has adopted NFPA 5000. The model building code used in Canada is the NBCC, which is promulgated by National Research Council of Canada. Building codes regulate the properties of materials and the methods of construction as they pertain to the hazards presented by various occupancies. They are based on the findings of previous experiences such as fires, earthquakes, and structural collapses. Require- ments found in building codes that have an impact on fire protection include enclosures of vertical openings such as stair shafts, elevator hoistways (shafts), pipe chases, exit requirements, flame spread requirements for interior finishes, fire alarm requirements, and sprinkler requirements. The evaluation of the risk to a building with respect to fire resistance has been a goal of building codes, fire codes, and insurance underwriters for years. For this reason, buildingcodes have classified constructiontypes and controlled the size of buildings based on the poten- tial fire hazard. Each building code identifies various construction types, and although each code may classify the various types of construction differently, the classifi- cation system is essentially the same for all. Originally, there were only two classifications, “fireproof” and “nonfireproof.”
