The ISO standards for sand casting mainly include the following:
Foundry Sand Testing Standards
ISO 10070: Foundry sand particle size analysis method (sieve method)
ISO 7979: Foundry sand – Determination of loss on ignition (LOI)
Casting Quality Standards
ISO 11971: Visual inspection method for surface quality of cast steel parts (corresponding to GB/T 39428)
Other Related Standards
ISO 679: Chemical composition requirements for standard sand (silica content > 96%, loss on ignition ≤ 0.4%)
These standards cover the physical and chemical property testing of foundry sand and the surface quality acceptance requirements for castings, and are applicable to different process scenarios.
Generally speaking, most engineering companies that provide casting services have ISO certification, as this is a prerequisite for starting a business, so there’s no need to worry.
