IEC 60335-2-7:2008+A1:2011 deals with the safety of electric washing machines for household and similar use, that are intended for washing clothes and textiles, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. This standard also deals with the safety of electric washing machines for household and similar use employing an electrolyte instead of detergent. Additional requirements for these appliances are given in Annex CC.

This publication is to be read in conjunction with IEC 60335-1:2010.

This consolidated version consists of the seventh edition (2008) and its amendment 1 (2011). Therefore, no need to order amendment in addition to this publication.

IEC 62149-7:2012 covers the performance specification for 1 310-nm discrete vertical cavity surface emitting laser (VCSEL) devices of transverse single-mode and multimode types used for the fibre optic telecommunication and optical data transmission application in a form of the VCSEL chips mounted on a substrate with wire bonding to their chips' anode and cathode terminals without any fibre pigtails. The performance standard contains a definition of the product performance requirements together with a series of sets of tests and measurements with clearly defined conditions, severities, and pass/fail criteria. Keyword: vertical cavity surface emitting laser (VCSEL).

This document specifies the use of relevant functions for delivery of an IPTV Content on Demand (CoD) Service. An instance of an IPTV CoD Service may be configured to provide a consumer experience similar to that of traditional Video on Demand (VoD) television services. Additionally, the service supports protocols (e.g., HTTP) for direct access to consumer electronic devices. Content may be sourced from within the service provider or across the Internet directly from the content provider. Content can also be delivered to subscriber devices attached to either the service provider?s managed network or a third party unmanaged network (e.g., Content Delivery Network). These CoD service capabilities allow for nomadic service across multiple networks and devices.

Published: Will ship as published throughout the year.

ISO/IEC TR 24748-3:2011 is adopted by this standard. ISO/IEC TR 24748-3:2011 is a guide for the application of ISO/IEC 12207:2008. It addresses system, life cycle, process, organizational, project, and adaptation concepts, principally through reference to ISO/IEC TR 24748-1 and ISO/IEC 12207:2008. It gives guidance on applying ISO/IEC 12207:2008 from the aspects of strategy, planning, application in organizations, and application on projects. ISO/IEC TR 24748-3:2011 is intentionally aligned with both ISO/IEC TR 24748-1 and ISO/IEC TR 24748-2 (Guide to the application of ISO/IEC 15288) in its terminology, structure and content.

The purpose of this document is to provide guidance on the application of pulsation and vibration control requirements found in the API purchasing specifications for positive displacement machinery. The fundamentals of pulsation and piping system analysis are presented in this Part.

The text begins with an overview of the fundamentals of pulsation and mechanical theory in Section 3. The intent of Section 3 is to introduce terminology and define the elements of the analysis process. Section 4 begins with a discussion of the acoustic and mechanical modeling techniques associated with the different design philosophies, which emphasize either pulsation or mechanical control, and concludes with a discussion on the appropriate selection of a Design Approach and Philosophy. Section 5 discusses the effects of pulsation on the accuracy of various types of flow measurement devices. Section 6 summarizes the requirements for documenting study results. Section 7 offers guidance on the performance of field testing to validate the results of the design process and to troubleshoot pulsation or vibration problems. Finally, methodologies for conducting a dynamic analysis of the compressor or pump valve performance are described in Section 8. The material in this Part is generally applicable to all types of positive displacement machinery.

Part 2 deals specifically with reciprocating compressors and provides commentary regarding each paragraph of Clause 7.9 of API 618, 5th Edition. It is the intent of the API Subcommittee on Mechanical Equipment that similar material be provided on reciprocating pumps and screw compressors in future editions.

The Unified Ordering Model (UOM) describes a complete set of system documentation using an end-to-end structured methodology. The scope of UOM encompasses business requirements, analysis, design and implementation. Logically, these components are defined within the UOM in four volumes.

Volume I provides an explanation of the business requirements and a high-level conceptual overview of the solution. It also includes the Business Process Definition, Business Validation Rules, Scenarios and Activity Diagrams.

This standard provides network-to-customer installation (CI) interface requirements for the connection of a Public Safety Answering Point (PSAP) CI to a network providing access to an Enhanced 911 switching system. The inter-face uses loop reverse-battery signaling with a CI-provided battery source. The inter-face allows users of the En-hanced 911 system to communicate with the PSAP CI and allows the Enhanced 911 system to transmit the caller's emergency service identification (CESID) information to the PSAP CI.
