CISPR 32 Ed. 1.0 b:2012

Electromagnetic compatibility of multimedia equipment – Emission requirements

Edition: 1.0
International Special Committee on Radio Interference / 30-Jan-2012 / 166 pages

CISPR 32:2012 International Standard applies to multimedia equipment (MME) having a rated r.m.s. AC or DC supply voltage not exceeding 600 V. Equipment within the scope of CISPR 13 or CISPR 22 is within the scope of this publication. MME intended primarily for professional use is within the scope of this publication. The radiated emission requirements in this standard are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions. Equipment, for which emission requirements in the frequency range covered by this publication are explicitly formulated in other CISPR publications (except CISPR 13 and CISPR 22), are excluded from the scope of this publication. This document does not contain requirements for in-situ assessment. Such testing is outside the scope of this publication and may not be used to demonstrate compliance with it. This publication covers two classes of MME (Class A and Class B). The objectives of this publication are to establish requirements which provide an adequate level of protection of the radio spectrum, allowing radio services to operate as intended in the frequency range 9 kHz to 400 GHz and to specify procedures to ensure the reproducibility of measurement and the repeatability of results.

CSA Z259.2.3-12

Descent Devices (Adopted ISO 22159:2007, first edition, 2007-05-15, with Canadian deviations)

Canadian Standards Association / 01-Feb-2012 / 70 pages

Preface

This is the second edition of CAN/CSA-Z259.2.3, Descent devices, which is an adoption, with Canadian deviations, of ISO (International Organization for Standardization) Standard 22159 (first edition, 2007-05-15), entitled Personal equipment for protection against falls – Descending devices. The title has been changed for the CSA Standard to reflect the modification of the scope of the adopted ISO Standard.

Scope

This International Standard specifies requirements, test methods, marking and information to be supplied by the manufacturer for descending devices. It also specifies some basic requirements for the descent lines to be used with the descending devices.

This International Standard is applicable to automatic and manually operated descending devices intended for use in the workplace in access, egress, work positioning and rescue systems. Various types and classes of descending devices are defined according to function and performance. These descending devices can be used in situations other than the workplace if adequate training and/or supervision are provided.

This International Standard is not intended to apply to descending devices used in leisure activities such as recreational climbing and caving, although its requirements can be useful in specifying such equipment.

NOTE Descending devices conforming to this International Standard can be designed for use by one or two persons simultaneously.

AMCA 205-10

Energy Efficiency Classification for Fans

Air Movement and Control Association / 17-Jan-2012 / 17 pages

This standard defines the energy efficiency classification for
fans. The scope includes fans having an impeller diameter
of 125 mm (5 in.) or greater, operating with a shaft power
750 W (1 hp) and above, and having a total efficiency calculated
according to one of the following fan test standards:
ANSI/AMCA 210, ANSI/AMCA 230, AMCA 260, or ISO 5801.
All other fans are excluded. The standard only applies to the
fan, not the fan drive or the fan system.

This standard can be used by legislative or regulatory bodies
to define the energy efficiency requirements of fans used
in specific applications.

ANSI/ASME B18.12-2012

Glossary of Terms for Mechanical Fasteners

American Society of Mechanical Engineers / 23-Feb-2012 / 72 pages

This Standard is a summary of nomenclature and terminology currently used to define and/or describe mechanical fasteners, related characteristics, and the manufacturing processes that produce these products. Utilization of these terms by manufacturers and consumers is intended to reduce or eliminate confusion and serve as a sound basis for communication.

(a) Primary Operations. Mechanical fasteners are produced by forming or screw machine operations. Forming is generally scrapless and, depending upon size, may produce fasteners at rates exceeding 500 pieces per minute. Screw machining, although more tightly toleranced, is significantly slower and generates scrap because it involves the removal of material.

(b) Secondary Operations. Fasteners generally undergo several secondary operations or processes such as thread rolling, heat treating, or plating.

(c) Fastener. A fastener is a mechanical device designed specifically to hold, join, couple, assemble, or maintain equilibrium of single or multiple components. The resulting assembly may function dynamically or statically as a primary or secondary component of a mechanism or structure. Based on the intended application, a fastener is produced with varying degrees of built in precision and engineering capability, ensuring adequate, sound service under planned, preestablished environmental conditions.
(d) Bolts, Studs, Screws, Nuts, Washers, Rivets, Pins, and Custom Formed Parts. These items are the general product families in which mechanical fasteners are best classified. Within each product family are numerous types that may have a name conforming to the technical language of a national standard or alternately may have a name that has its origins in commercial or marketing nomenclature often taken from its intended application. Such names, for example, include the "stove bolt" and "carriage bolt."

Because mechanical fasteners are used in just about every mechanical assembly, they necessarily have been designed to meet a broad range of applications from watch and computer assembly to space shuttle design. The names given to fasteners appear to be as limitless as the designer's imagination. While many fasteners may look alike, they generally have defined engineered capabilities based upon their intended application.
