GOST R ISO 14644-1-2017

ГОСТ Р ИСО 14644-1-2017

Cleanrooms and associated controlled environments. Part 1. Classification of air cleanliness by particle concentration

Чистые помещения и связанные с ними контролируемые среды. Часть 1. Классификация чистоты воздуха по концентрации ч��стиц

Status: Effective - Introduced for the first time. IUS 2-2018

This standard establishes the classification of clean air in clean rooms according to the concentration of aerosol particles in clean rooms and clean zones, as well as in insulating devices according to ISO 14644-7. For classification purposes, only a cumulative distribution is applicable, based on threshold particle sizes (lower limit) in the range of 0.1 to 5 microns. The concentration of aerosol particles with dimensions equal to or greater than the specified value should be determined at the required sampling points using discrete laser particle counters operating on the principle of light scattering. This standard does not establish a classification for particles with threshold sizes outside the range of values from 0.1 to 5 microns. Classification for ultrafine particles (with sizes less than 0.1 microns) is set in a separate standard for the classification of air cleanliness for particles with sizes in the nano-range. For the quantitative description of particulates (with dimensions greater than 5 microns) M descriptor can be used. The classification of surface cleanliness by particle concentration (SCP) is limited to particle sizes from 0.05 μm to 500 μm. This standard cannot be used to describe the physical, chemical, radiation, biological and other properties of aerosol particles.

Настоящий стандарт устанавливает классификацию чистоты воздуха в чистых помещениях по концентрации аэрозольных частиц в чистых помещениях и чистых зонах, а также в изолирующих устройствах по ИСО 14644-7. Для целей классификации применимо только кумулятивное распределение, основанное на пороговых размерах частиц (нижний предел) в диапазоне от 0,1 до 5 мкм. Концентрацию аэрозольных частиц с размерами равными или большими заданного значения следует определять в требуемых точках отбора проб с помощью дискретных лазерных счетчиков частиц, работающих по принципу рассеяния света. Настоящий стандарт не устанавливает классификацию для частиц с пороговыми размерами, выходящими за пределы значений от 0,1 до 5 мкм. Классификация для ультрамелких частиц (с размерами менее 0,1 мкм) устанавливается в отдельном стандарте по классификации чистоты воздуха для частиц с размерами в нанодиапазоне. Для количественного описания макрочастиц (с размерами более 5 мкм) может использоваться М дескриптор. Классификация чистоты поверхностей по концентрации частиц (SCP) ограничена размерами частиц от 0,05 мкм до 500 мкм. Настоящий стандарт не может использоваться для описания физических, химических, радиационных, биологических и других свойств аэрозольных частиц
