ITU-R P.845-3-1997 高频场强测量

Measurements of sky-wave signal intensities, if undertaken in a carefully controlled manner, are of value in assessing the accuracy of methods for estimating field strength and transmission loss.

HF Field-Strength Measurement

UL 586-1996 高效微粒子空气滤波器元件

1.1 These requirements cover high-efficiency, particulate, air-filter units intended for the removal of very fine particulate matter (not less than 99.97 percent of 0.3 micron diameter particles) from the air of industrial and laboratory exhaust and ventilating systems. 1.2 These requirements cover single air filter units. 1.3 These requirements do not cover multiple assembly air filter units. 1.4 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.

IEC 60368-2-2:1996 压电滤波器 第2部分:压电滤波器使用指南 第2节:压电陶瓷滤波器

This section of IEC 368-2 describes passive band-pass filters operating over the frequency range of a few kHz to more than 10 MHz which are commercially available as separate and independent units. It is not the aim of this standard to explain theory, nor to attempt to cover all the eventualities which may arise in practical circumstances. This standard draws attention to some of the fundamental questions which should be considered by the user before he places an order for a filter for a new application. Such a procedure will be the user's insurance against unsatisfactory performance.
