Particulate air filters for general ventilation. Standardised dimensions1 Scope This European Standard specifies the header frame dimensions of air filters for general ventilation to be used in air handling units, air intake system filters for rotary machinery and other applications. This includes pocket filters, rigid (V type) filters and filters to which header frame dimensions are applicable.

This Technical Specification is applicable to a wide variety of measurements

will ensure proper and consistent identification for substances conveyed through the valves and eliminates accidents and injuries arising from improper valve identification

Annex F (informative) Existing requirements for aerosol filters

– watt-hour meters where the voltage across the connection terminals exceeds 600 V (line-to-line voltage for meters for polyphase systems)

After the incubation

you can standardize skeletal pins and wires used in orthopaedic surgery

It follows that the sterility of any one product in a population subjected to sterilization cannot be guaranteed and the sterility of a processed population is defined in terms of the probability of there being a viable micro-organism present on a product item

and requirements of geotextiles and geotextile-related products which make ease earthworks

The direct method can be applied in the frequency range from 1 Hz up to a frequency that is usually determined by the lowest resonance frequency of the test arrangement frame (typically 300 Hz for test rigs with dimensions of the order of 1 m)
