为了向公众宣传标准在日常生活中的重要作用,美国国家标准协会(ANSI)经常发布在全球和本国标准领域开展的各种标准活动的快报,其中许多活动是由ANSI会员及ANSI认可的标准制定组织开展的。以下是两项最新的标准:

一、有关梯子标准

据美国劳工部职业安全和健康管理局(OSHA)报告,从便携梯子上摔倒(台阶、直梯、组合梯、伸缩梯)是造成工作死亡和受伤的主要原因之一。

由美国梯子研究所(ALI)制定的ANSI ASC A14 梯子标准,是美国国家标准的梯子标准汇编,为不同类型梯子的制造、设计、测试、保养、使用、贴标签、评价提供标准要求。梯子包括固定梯、便携式增强塑料梯、便携式金属锑、木梯等等。

ALI是ANSI成员并得到ANSI认可的标准制定组织,它是一家非盈利性会员组织,通过制定及宣传有关梯子设计、制造、测试、保养和使用的标准,为整个北美地区的梯子及部件制造商服务。ALI还致力于普及安全使用梯子的知识,指导公众如何选择、保养以及安全地使用梯子。

二、饮用水蒸馏

蒸馏利用热源让水蒸发,在此过程中水中几乎所有杂质都能被去除,包括大部分矿物质、大部分细菌和病毒,以及任何比水沸点高的化学物质。

NSF/ANSI 62-2017——饮用水蒸馏系统为末端和入口饮用水蒸馏系统及其部件制定最少的材料使用量、设计和制造规格以及性能要求。

美国国家标准(ANS)由国家科学基金会(NSF)饮用水处理装置联合委员会制定。该标准所涉及的系统旨在减少水中影响审美品质的物质或/和添加用于防垢的化学物质,或两者兼而有之。。

作为ANSI会员和被其认可的标准制定组织——NSF国际负责制定公共健康标准、协议和测试,为水、食品以及消费品工业开展产品认证。

 

Voluntary Standards Cover the Spectrum: from Ladders to Drinking Water Distillation Systems

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:

Ladder Standards

According to the U.S. Department of Labor's Occupational Safety & Health Administration (OSHA), falls from portable ladders (step, straight, combination, and extension) are one of the leading causes of occupational fatalities and injuries.

The ANSI ASC A14 Ladder Standards Package, developed by the American Ladder Institute(ALI), is a comprehensive collection of American National Standards that provides the requirements for the construction, design, testing, care, use, labeling, and marking of various types of ladders. The ladders include fixed, portable reinforced plastic, portable metal, wood, and more.

ALI, an ANSI organizational member and accredited standards developer, is a not-for-profit membership association serving ladder and components manufacturers throughout North America through the development and disseminate of standards for design, construction, testing, care, and use of ladders. ALI is also dedicated to promoting ladder safety and works to educate the public on the selection, care, and safe use of ladders.

Drinking Water Distillation

The distillation process, which utilizes a heat source to vaporize water, removes nearly all impurities from drinking water, including most minerals, most bacteria and viruses, and any chemicals that have a higher boiling point than water.

NSF/ANSI 62-2017, Drinking Water Distillation Systems, establishes minimum materials, design and construction, and performance requirements for point-of-use and point-of-entry drinking water distillation systems and the components used in these systems.

The American National Standard (ANS) was developed by the NSF Joint Committee on Drinking Water Treatment Units. Systems covered under the standard are intended to reduce substances affecting the aesthetic quality of the water or to add chemicals for scale control, or both.

An ANSI member and accredited standards developer,NSF International writes public health standards and protocols and tests, and certifies products for the water, food, and consumer goods industries.
