Voluntary Standards Cover the Spectrum: from Molding Machines to Fiber Optics

New York, Aug 15, 2014

In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:

Molding Machines
Molding machines use metals, glass, elastomers, thermoplastics, and polymers to create molds of wire, packaging, bottle caps, automotive and mechanical parts, combs, musical instruments, plastic products, and innumerable other industrial and household items. To protect personnel working on or adjacent to vertical clamp injection molding machines (VCIMMs), a revised American National Standard (ANS) has been published by SPI – The Plastics Industry Trade Association.

ANSI/SPI B151.29-2014, Safety Requirements for Vertical Clamp Injection Molding Machines, applies to VCIMMs that process plastic materials and inject the materials into molds held closed by a vertically acting clamp. Revisions to the new edition of ANSI/SPI B151.29-2014 include advances in safety-related controls, mechanisms, and practices and expanded definitions and references for recommended safety procedures and circuit. Safety requirements for the use of ancillary equipment or molds for VCIMM are not covered by ANSI/SPI B151.29-2014.

SPI, an ANSI organizational member and accredited standards developer, is a non-profit organization that promotes the growth of the plastics industry through legislative and regulatory advocacy, market research, industry promotion, and standardization while pursuing zero waste strategies for the U.S. plastics industry.

Fiber Optics
Fiber optics are used by telecommunications companies to inexpensively transfer telephone, internet, and cable data between home and business workstations, mainframes, supercomputers, desktop computers, storage devices, and more. The technology uses the open system interconnection (OSI) model, which defines a networking framework to implement protocols in seven layers. To ensure the seven layers “stack” accurately and operate as intended, the Consumer Electronic Association (CEA) recently released ANSI/CEA 709.4-2013, Fiber-Optic Channel Specification.

This ANS, in conjunction with ANSI/CEA 709.1, Control Network Protocol Specification, specifies the physical layer (OSI Layer 1) requirements for the fiber optic channel that encompasses the interface to the media access control (MAC) layer and the interface to the medium. The single-fiber channel specified in ANSI/CEA 709.4-2013 allows two nodes to communicate bi-directionally across a single piece of fiber cable, minimizing complexity of the fiber interconnect.

CEA, an ANSI organizational member and accredited standards developer, is a non-profit organization dedicated to the consumer technology industry. CEA serves its membership and stakeholders through market research, advocacy, educational programs, technical training, standardization, and certification programs.
