Abstract
Overview
ISO 8656-1:1988 - "Refractory products - Sampling of raw materials and unshaped products - Part 1: Sampling scheme" specifies standardized methods and conditions for taking representative samples of raw refractory materials and prepared unshaped refractory products. It defines sampling principles (increments, bulk sample, laboratory/test samples), rules for sample protection and preparation, and how to choose sampling intensity to achieve a required sampling precision. The part is intended to provide a reproducible for quality control and specification verification; it excludes very large static quantities or cargoes from which reliable samples cannot be taken.
