This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

RAW MATERIALS
clay, n—an earthy or stony mineral aggregate consisting essentially of hydrous silicates of alumina, plastic when sufficiently
pulverized and wetted, rigid when dry, and vitreous when fired to a sufficiently high temperature.
fire clay, n—a sedimentary clay of low flux content.
reactive particulates, n—a particle or particles present in a clay body, which when near the surface may flake off or cause an
eruption (pop-outs) of the surface when exposed to the weather.
shale, n—a thinly stratified, consolidated, sedimentary clay with well-marked cleavage parallel to the bedding.

MANUFACTURE
body color—the range of color obtained when materials used to form the brick react to the effects of firing temperature and
atmosphere.
DISCUSSION—There may be additives in the body to produce a desired color. When no materials are added to the surface of the brick and the unit
is not flashed when fired, the body color is also the through-body color, a surface feature.
cells/core holes, n—continuous openings or perforations within extruded clay products.
DISCUSSION—The extent of permissible openings is specified for each product as the percentage of gross area in the normal bedding surface plane
that must be net (solid) area. Core hole is generally used for brick while cell is used for structural tile. Cells are distinguished from core holes by being
