Acoustics — Noise from shooting ranges — Part 3: Sound propagation calculations
This document specifies methods of predicting the sound exposure level of shooting sound for a single shot at a given reception point. Guidelines are given to calculate other acoustic indices from the sound exposure level. The prediction is based on the angular source energy distribution of the muzzle blast as defined in ISO 17201-1 or calculated using values from ISO 17201-2.

Semiconductor devices - Non-destructive recognition criteria of defects in silicon carbide homoepita...
IEC 63068-1:2019(E) gives a classification of defects in as-grown 4H-SiC (Silicon Carbide) epitaxial layers. The defects are classified on the basis of their crystallographic structures and recognized by non-destructive detection methods including bright-field OM (optical microscopy), PL (photoluminescence), and XRT (X-ray topography) images.
Semiconductor devices - Non-destructive recognition criteria of defects in silicon carbide homoepita...
IEC 63068-2:2019(E) provides definitions and guidance in use of optical inspection for detecting as-grown defects in commercially available 4H-SiC (Silicon Carbide) epitaxial wafers. Additionally, this document exemplifies optical images to enable the detection and categorization of the defects for SiC homoepitaxial wafers. This document deals with a non-destructive test method for the defects so…
