BS EN 13087-6 on protective helmets’ field of vision is useful for:

This International Standard specifies a method to provide a relative measure for evaluating the resistance of direct reduced iron to size degradation by impact and abrasion

These interactions are assumed to occur at various scales of propinquity and at various intensities across the "personal privacy sphere"

Hydrometry. Suspended sediment in streams and canals. Determination of concentration by surrogate techniques Ingestion-build-264231 BS EN 13087-6 on protective1 Scope This International Standard specifies methods for determination of the concentrations and particle size distributions of suspended sediment in streams and canals by surrogate techniques. Methods based on bulk optical principle of water such as transmission and nephelometry are the most commonly used surrogates for determining suspended sediment concentrations (SSC). Instruments and techniques based on acoustic attenuation and or acoustic
