为了证明标准在日常生活中的重要作用,美国国家标准协会(ANSI)发布了报告,对全球各类标准和国家标准进行了报道,其中大部分标准是由ANSI成员和由ANSI认可的标准制定组织完成,以下是两个最新的实例
1 关于磁线
磁线,也称漆包线,是一种绝缘筒,通常用于各式电磁设备的制造,例如发动机和变压器。国家电气制造商协会(NEMA)近期修订了“ANSI/NEMA MW 1000-2016磁线”标准。此项标准涵盖圆形、矩形、正方形薄膜和/或纤维包磁线,以及用于制造电气设备的铝磁线。标准内容包括广泛用于电气设备内部线圈缠绕的磁线的使用范围、型号命名、尺寸、制造、性能和测试方法。
NEMA表示,对此项标准的修订包括新规格的确定,这将明确120级聚乙烯醇缩薄膜绝缘磁线的制造要求。同时,还能利用圆筒法测试各类规格电线的电介质击穿特性,这种方法比双绞线检验试片更加方便。
NEMA是ANSI的成员之一,也是经其认可的标准制定组织,制定了这项美国国家标准(ANS)。NEMA代表着将近400家位于电气安全、可靠性、复原力、效能和能源安全等领域前沿的电气、医疗成像和放射治疗设备制造商。该行业在美国全境有超过7000家工厂,为全美增加40万个就业岗位。
2 关于信息技术设备的火灾防控
由于世界越来越依赖信息技术,从数据系统到各类设备和通信服务,因此对于企业经营来说,IT设备的火灾防控至关重要。美国消防协会(NFPA’s)的“NFPA 75-2017信息技术设备火灾防控”标准–2017版规定了防止IT设备因火灾及其相关影响受到损害(包括烟雾、腐蚀、高温和水)的最低要求。
NFPA是ANSI的成员之一,也是其认可的标准制定组织。NFPA一直致力于制定和提高协商一致的规范和标准,推动消防相关的研究、培训和教育。同时它还通过制定相关程序来预防火灾发生、降低已发生的火灾的影响以及保证消防员的安全和健康。
Voluntary Standards Cover the Spectrum: from Magnet Wire to Fire Protection of Information Technology Equipment
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:
Magnet Wire
Magnet wire, also called enameled wire, is insulated copper used in the construction of various electromagnetic equipment, including motors and transformers. The National Electrical Manufacturers Association (NEMA) recently revised the standard ANSI/NEMA MW 1000-2016 Magnet Wire, which contains standards for round, rectangular, and square film-insulated and/or fibrous-covered copper and aluminum magnet wire for use in electrical apparatus. Included are the definitions, type designations, dimensions, constructions, performance, and test methods for magnet wire generally used in the winding of coils for electrical apparatus.
According to NEMA, revisions to MW 1000 include new specifications that define the requirements for Class 120 polyvinyl acetal film insulated wire constructions. Also, a larger range of wire sizes can now be tested for dielectric breakdown using the cylinder method, which is a more convenient way of testing than making twisted pair test specimens.
NEMA, an ANSI member and accredited standards developer, developed this American National Standard (ANS). NEMA represents nearly 400 electrical, medical imaging, and radiation therapy manufacturers at the forefront of electrical safety, reliability, resilience, efficiency, and energy security. Its combined industries account for more than 400,000 American jobs and more than 7,000 facilities across the U.S.
Fire Protection of Information Technology Equipment
As the world increasingly depends on information technology for everything from data systems to devices and telecom services, protection of the IT equipment essential to business operations is imperative. The National Fire Protection Association’s (NFPA’s) NFPA 75-2017 Standard for the Fire Protection of Information Technology Equipment, 2017 edition sets forth the minimum requirements for the protection of IT equipment from damage by fire or its associated effects – namely, smoke, corrosion, heat, and water.
NFPA, an ANSI member and accredited standards developer, is committed to producing and promoting consensus codes and standards, research, and training and education, and works to prevent fires as well as to lessen the impact of fires when they do occur, which includes developing procedures that will keep firefighters safe and healthy.
