Establishing Levels of Selective Coordination for Low Voltage Circuit Breakers

National Electrical Manufacturers Association / 12-Dec-2011 / 20 pages

Addresses achieving selective coordination at high levels of short circuit fault current in the instantaneous region of the circuit breaker time-current curve by use of selective coordination tools. This requires taking into consideration more information than is typically found on conventional Time-Current Curves TCCs only. This includes molded case circuit breakers and insulated case circuit breakers. It specifically addresses instantaneous selective coordination as achieving selective coordination at high levels of fault current, and may require taking into consideration more information than is typically found on conventional Time-Current Curves TCCs only.

Information Technology – Biometric Performance Testing and Reporting – Part 5: Framework for Testing and Evaluation of Biometric System(s) for Access Control

InterNational Committee for Information Technology Standards (formerly NCITS) / 05-Dec-2011 / 43 pages

This standard specifies a framework for testing and reporting of biometric system(s) used in applications
supporting access control. It specifies the environment that testing will be performed
in, the evaluation metrics, demographic controls, and the means by which testing will be performed
and how the graded results will be reported. The intent of this testing framework is to provide
a ?one size fits many? approach to re-usable test results, centered on typical access control
requirements

Standard for Competency of Third-Party Field Evaluation Bodies, 2012 Edition

National Fire Protection Association / 2012 / 24 pages

Installed electrical products or assemblies that are not previously certified, listed, recognized, or classified undergo a "field evaluation" to ensure electrical safety. Newly created to meet industry needs, the 2012 edition of NFPA 790: Standard for Competency of Third-Party Field Evaluation Bodies provides qualifications and competencies for third parties performing field evaluations and specifies how they are to be completed.

Used in tandem with the new NFPA 791: Recommended Practice and Procedures for Unlabeled Electrical Equipment Evaluation, this Standard is essential for personnel involved with evaluating:

? Electrical products not pre-certified, listed, recognized, or classified to an applicable product safety standard

? Electrical products and assemblies that are unique or modified after the manufacturing process

Users of this first-time Standard include fire marshals and AHJs.

Comprehensive guide to steam sterilization and sterility assurance in health care facilities, Amendment 2

Association for the Advancement of Medical Instrumentation / 19-Sep-2011 / 134 pages

This recommended practice covers steam sterilization in health care facilities. The
recommendations are intended to promote sterility assurance and to guide health care
personnel in the proper use of processing equipment. Included within the scope of the
recommended practice are functional and physical design criteria for sterilization processing
areas (decontamination, preparation, sterilization, and sterile storage areas); staff
qualifications, education, and other personnel considerations; processing procedures;
installation, care, and maintenance of steam sterilizers; quality control; and quality process
improvement.

Safety Standard for Platform Lifts and Stairway Chairlifts

American Society of Mechanical Engineers / 31-Oct-2011 / 80 pages

The ASME A18.1 Safety Standard for Platform Lifts and Stairway Chairlifts presents certain guides for the design, construction, installation, operation, inspection, testing, maintenance, and repair of inclined stairway chairlifts, and inclined and vertical platform lifts. It covers devices intended for transportation of a mobility-impaired person only ? typically for applications within buildings and residences.

The ultimate goal of this Standard is to help protect public safety, while reflecting best-practices of industry.

A18.1 offers essential guidance for safety to both public and private sectors:

  • For public sectors, it serves as the basis for state, municipal, and other jurisdictional authorities in drafting regulations governing the installation, testing, inspection, maintenance, alteration, and repair of stairway chairlifts and platform lifts.
  • For private sectors, A18.1 provides a standard reference of safety requirements for architects, engineers, insurance companies, manufacturers, and contractors, while delivering safety practices for owners and managers of structures where equipment covered in the Scope of this Standard is used.
