本眼部和面部保护装置标准是以性能为导向的。 我们尽了一切努力来制定要求，确保佩戴者得到保护 符合或优于ANSI Z87 1-1979。新标准承认 美国劳工统计局（Bureau of Labor Statistics）的一项研究显示，英国需要角保护 除了正面保护。美国焊接学会的一项研究结果 已用于更新和改进设备的透射率要求 用于防止光辐射。 （23位数字、选择图表、测试） 仪器，五个附录。）

This standard for eye and face protective devices is performance-oriented in intent. Every effort was made to develop requirements that assure the wearer of protection consistent with or better than ANSI Z87 1-1979. The new standard recognizes the Bureau of Labor Statistics study that revealed the need for angular protection in addition to frontal protection. Results of a study by the American Welding Society have been used to update and improve requirements for transmittance of devices intended for protection against optical radiation.
