Title:
BS EN ISO 22282-2:2012 – Geotechnical investigation and testing. Determination of permeability of soil and rock using field testing
Air Permeability Tests
- Hardness scale: Vickers or Rockwell scales specified; conversion tables may be used with caution.
- Report must include: steel designation and chemical composition, specimen dimensions and surface condition, austenitizing temperature and time, quench medium and flow conditions, nozzle geometry, hardness measurement method and values (tabulated), graph of hardness vs. distance (Jominy curve), and any deviations from standard procedure.
- Where applicable, report effect of tempering or other heat treatments applied after quenching.
groundwater conditions
Establish above and below the water table.
