Standard Practice for Determining the Maintenance Factor (m) and Yield Factor (y) Loading Constants Applicable to Gasket Materials and Designs
N F3149
Annotation
This practice will establish criteria for determining loading constants that are referenced in the American Society of Mechanical Engineers (ASME) pressure vessel design (Boiler and Pressure Vessel Code, Section VIII, Divs. 1 and 2). These constants are specific to this design criterion for metallic, semi-metallic, and nonmetallic gaskets.
Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Общепринятая практика для определения фактора обслуживания (m) и коэффициент запаса (y) погрузка констант, применимых к материалам прокладки и проектам
Эта практика установит критерии определения загружающихся констант, на которые ссылаются в Американском обществе инженеров-механиков (ASME) дизайн камеры высокого давления (Бойлер и Код Камеры высокого давления, Раздел VIII, Отделения 1 и 2). Эти константы являются определенными для этого критерия разработки для металлических, полуметаллических, и неметаллических прокладок.
