Air quality. Sampling conventions for airborne particle deposition in the human respiratory system Ingestion-build-67170 BS EN IEC 60749‑17 on

BS EN IEC 60749‑17 on Semiconductor devices is applicable to:

Specifying round tube sizes and tolerances

The testing guidelines provided in BS EN 3842 could aid towards the efficiency and durability of the tubes

horizontal European release/emission test methods are the reference methods

Air quality. Sampling conventions for airborne particle deposition in the human respiratory system Ingestion-build-67170 BS EN IEC 60749‑17 on1 Scope This International Standard specifies sampling conventions to define idealized samplers for estimating the deposition of non volatile, non hygroscopic, non fibrous aerosols in five specific loci of the respiratory tract. The five loci consist of the anterior and posterior areas of the nasal passages, the ciliated and non ciliated parts of the tracheobronchial area, and the alveolar (gas exchange) region. The conventions are separated into
