Sets out the methodology for the acceptance testing of refractory products based on minimum quality levels associated with an agreed specification.

This Standard sets out the methodology for the acceptance testing of refractory products based on minimum quality levels associated with an agreed specification.The Standard is suitable for shaped or unshaped products, raw materials or for a product in an intermediary phase. This Standard is applicable to all situations where a minimum quality level, as opposed to a mean quality level, is required for harm minimization.This Standard does not cover the varied quality control methods used to meet performance requirements.
