Description (English):

ISO 4365:2005 specifies methods for determining the concentration, particle-size distribution and relative density of sediment in streams and canals. The detailed methods of analysis are given for the following: determination of the suspended sediment concentration by evaporation and filtration; particle-size analysis of suspended sediment; determination of the bed-load and bed material sediment; determination of the relative density of sediment; determination of particle-size distribution characteristics.

Abstract

Overview

ISO 4365:2005 - "Liquid flow in open channels - Sediment in streams and canals - Determination of concentration, particle size distribution and relative density" specifies standardized laboratory and analytical methods for characterizing sediment in streams and canals. The standard defines procedures to determine suspended sediment concentration, particle‑size distribution (for suspended sediment, bed-load and bed material) and relative density of sediment. Detailed methods and laboratory procedures are provided in normative annexes (A–G).

Key Topics and Requirements

Scope and definitions: Terms such as suspended load, bed-load, nominal/sieve/settlement diameters and relative density are defined in accordance with ISO vocabulary conventions.
Sampling linkage: Suspended sediment sampling is referenced to ISO 4363; correct sampling is a prerequisite for analysis.
Concentration methods:
- Evaporation method (Annex A) - mass determination after drying (suitable for coarser particles).
- Filtration methods (Annex B, C) - filter paper or glass‑fibre/Gooch/Coors/Alundum crucibles with vacuum filtration; annexes note advantages/limitations (e.g., potential loss of very fine particles).
- Hydrometer method - referenced for some sizing/concentration tasks (noted as temperature‑sensitive).
Particle‑size analysis:
- Classification by size ranges: coarse (>0.25 mm), medium (0.062–0.25 mm), fine (
