Standard Test Method for Water Vapor Transmission Rate Through Plastic Film and Sheeting Using a Modulated Infrared Sensor
N F1249
Annotation
This test method covers a procedure for determining the rate of water vapor transmission through flexible barrier materials. The method is applicable to sheets and films up to 3 mm (0.1 in.) in thickness, consisting of single or multilayer synthetic or natural polymers and foils, including coated materials. It provides for the determination of (1) water vapor transmission rate (WVTR), (2) the permeance of the film to water vapor, and (3) for homogeneous materials, water vapor permeability coefficient.
NOTE 1—Values for water vapor permeance and water vapor permeability must be used with caution. The inverse relationship of WVTR to thickness and the direct relationship of WVTR to the partial pressure differential of water vapor may not always apply.
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.

Метод стандартной пробы для темпа паропроницаемости через термопластическую пленку и покрывающий Используя смодулированный инфракрасный датчик
Этот метод испытаний покрывает процедуру для определения темпа паропроницаемости через гибкие материалы барьера. Метод применим к листам и фильмам до 3 мм (0.1 дюйма.) в толщине, состоя из единственных или многоуровневых синтетических или природных полимеров и фольги, включая покрытые материалы. Это предусматривает определение (1) темп паропроницаемости (WVTR), (2) permeance фильма к водяному пару, и (3) для гомогенных материалов, коэффициента проницаемости для водяных паров.
