ISO 1920-5:2018 PDF

Overview

ISO 1920-5:2018 - Testing of concrete - Part 5: Density and water penetration depth specifies internationally recognized methods to measure the density of hardened concrete and the depth of water penetration under pressure. The standard applies to lightweight, normal‑weight and heavy‑weight concrete and covers specimens in three conditions: as‑received, water‑saturated, and oven‑dried.

Key topics and technical requirements

• Scope: Methods for determining mass, volume and density of hardened concrete and for measuring water penetration depth under pressure.
• Specimen requirements: Minimum specimen volume of 1 L (larger minimums apply for mixes with big aggregate sizes - see the standard). Whole specimens or sawn specimens conforming to size rules may be used.
• Mass determination: Measurements permitted for as‑received, saturated and oven‑dried conditions. Oven drying at 105 °C ± 5 °C until mass change
