Voluntary Standards Cover the Spectrum: from Power Presses to Electrical Nerve Stimulators

New York, Oct 30, 2013

In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes a series of 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:

Power Presses
Hydraulic and pneumatic power presses are used throughout the manufacturing industry, to form, cut, join, pierce, bend, and trim metal for use in the construction of ships, bridges, engine parts, and numerous other applications. Hydraulic presses utilize forced water while pneumatic presses rely on pressurized air. Use of these machines can cause injury due to the risk of accidental misdirection of the released energy during production, maintenance, commissioning, and de-commissioning.

To protect individuals working with hydraulic and pneumatic power presses, B11 Standards, Inc. recently released ANSI B11.2-2013, Safety Requirements for Hydraulic and Pneumatic Presses. The requirements of this American National Standard (ANS) apply to hydraulically or pneumatically powered machines that transmit force to cut, form, or assemble metal or other materials by means of tools or dies attached to or operated by plungers or slides. ANSI B11.2-2013 covers manually fed presses; automatically fed presses; presses utilized for hydroforming, spotting, or tryout; transfer presses; tandem line presses; and presses used in production cells. ANSI B11.2-2013 should be used in tandem with ANSI B11.0-2010, Safety of Machinery: General Requirements and Risk Assessment, and ANSI B11.19-2010, Performance Requirements for Safeguarding.

B11 Standards, Inc., an ANSI organizational member and accredited standards developer, administers and develops the B11 series of ANS and technical reports on machines and machinery safety. B11 standards cover requirements applicable to the design, construction, installation, maintenance, and use of power-driven machines used to shape or form metal or other materials by cutting, impact, pressure, electrical techniques, or a combination of these processes.

Electrical Nerve Stimulators
Transcutaneous electrical nerve stimulation (TENS) is the use of electrical current to stimulate nerves for the therapeutic treatment of various types of acute and chronic pain conditions such as lower back pain, arthritis, and neurogenic, visceral, and post-surgical pain. TENS is commonly administered via portable stimulators connected to the skin using two or more electrodes.

To ensure the safety and effectiveness of TENS, the Association for the Advancement of Medical Instrumentation (AAMI) recently published ANSI/AAMI NS4-2013, Transcutaneous electrical stimulators. This new ANS establishes labeling, safety, and performance requirements, as well as referee tests, for portable, battery-powered TENS devices used in the treatment of pain syndromes. The non-invasive, low-risk treatment is intended for use on intact skin and mucous membranes that do not require surgical intervention or violation of the skin surface.

AAMI, an ANSI member and accredited standards developer, is dedicated to enhancing the ability of healthcare technology professions, healthcare institutions, and industry to understand, develop, manage, and use medical instrumentation and related technologies safely and effectively.
