ADOPTED_FROM:EN ISO 10414-1:2008 This part of ISO 10414 provides standard procedures for determining the following characteristics of water-based drilling fluids: a) drilling fluid density (mud weight); b) viscosity and gel strength; c) filtration; d) water, oil and solids contents; e) sand content; f) methylene blue capacity; g) pH; h) alkalinity and lime content; i) chloride content; j) total hardness as calcium. Annexes A through K provide additional test methods which may be used for chemical analysis for calcium, magnesium, calcium sulfate, sulfide, carbonate and potassium; determination of shear strength; determination of resistivity; removal of air; drill-pipe corrosion monitoring; sampling, inspection and rejection;
