Standard Test Method for Measuring Warpage of Ceramic Tile

SIGNIFICANCE AND USE
5.1 This test method provides a means for determining whether or not a lot of ceramic tile meets the warpage requirements that may appear in specifications to assure satisfactory tile installations. In accordance with this test method, warpage is calculated as a percentage of the length of the edge or diagonal being tested. It is realized that the percentage values based on the overall edge length, or on the overall diagonal length of a tile will be slightly lower than those based on the distance between reference points. However, the ratio of the overall lengths to the distance between reference points will be practically constant for any particular size of tile and, therefore, the percentage values will be comparable and equally indicative of warpage.
SCOPE
1.1 This test method covers procedures for measuring the corner, diagonal, and edge warpages of ceramic tile.  
1.1.1 Tile Requirements for Corner, Diagonal, and Edge Warpage Measurement
Tile should be nominally flat, uniform in overall thickness, smooth faced, and rectangular in shape, including square.  
1.1.2 Tile Requirements for Corner Warpage Measurement
All facial edge dimensions equal to or greater than 2.36 in. (60 mm) in length.  
1.1.3 Tile Requirements for Edge and Diagonal Warpage Measurement
All facial edge dimensions equal to or greater than 2 in. (51 mm) in length.  
1.1.4 Trim Tile meeting the descriptions in 1.1.1 – 1.1.3 except that only a part of the tile surface is flat. (Surface trim tile should be treated as flat tile whenever possible.)  
1.2 This test method is not applicable to tile having embossed surfaces that are not flat, or that have a combination of variable body thickness and an irregular face.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM C609-23(Test Method)
Standard Test Method for Measurement of Light Reflectance Value and Small Color Differences Between Pieces of Ceramic Tile

SIGNIFICANCE AND USE
5.1 This test method describes the means of determining the LRV of a tile specimen. Certain building codes require the use of materials rated by LRV. Application of this test method provides the means for rating ceramic tile. LRVs reported for ceramic tile should include reference to the observer and illuminant for which the rating is valid.  
5.2 LRV is a property dependent on the overall color of a tile specimen. Control of LRV is achieved through control of color and adherence to color specifications will govern the acceptability of a product with respect to LRV. Therefore, a product cannot be judged as having an unacceptable LRV unless the color of the product is found to be unacceptable.  
5.3 Mixtures of several tile products are commonly installed on a surface, requiring a means to calculate LRV for a product mix. The rating obtained for an individual tile product can be used to calculate the LRV for a product mix using the following equation:
   where:  
  n  =  number of products included in the mix,    p1 to n  =  the proportion of the surface area taken up by each product; the sum of p1 to pn must equal one), and   LRV1 to n  =  the LRV for each product used.    For example, a mixture of two products is used on a surface. Two thirds of the surface area is covered by product A with a LRV of 75 %, and one third of the surface is covered by product B with an LRV of 60 % (see Fig. 2). Using the equation, the product mix is found to have an LRV of 70 %.  
FIG. 2 Example of Product Mix Used on Surface
5.4 The test method described herein provides instrumental means as the basis for judging color difference. Magnitude of color difference between pairs of ceramic tile can be determined and expressed in numerical terms.  
5.5 Based on interlaboratory investigation,3 color difference ΔE  of plain-colored tile, if determined in accordance with this test method, should give excellent reproducibility with a standard deviation of not more than σ = ±...
SCOPE
1.1 This test method covers the measurement of Light Reflectance Value (LRV) and visually small color difference between pieces of glazed or unglazed ceramic tile, using any spectrophotometer that meets the requirements specified in the test method. LRV and the magnitude and direction of the color difference are expressed numerically, with sufficient accuracy for use in product specification.  
1.2 LRV may be measured for either solid-colored tile or tile having a multicolored, speckled, or textured surface. For tile that are not solid-colored, an average reading should be obtained from multiple measurements taken in a pattern representative of the overall sample as described in 9.2 of this test method. Small color difference between tiles should only be measured for solid-color tiles. Small color difference between tile that have a multicolored, speckled, or textured surface are not valid.  
1.3 For solid colored tile, a comparison of the test specimen and reference specimen should be made under incandescent, fluorescent and daylight illuminant conditions. The use of multiple illuminants allows the color difference measurement to be made without the risk of wrongly accepting a match when the tiles being compared are metamers (see 3.1.4).  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standard...

Standard Practice for Location of Test Specimens from Magnesia-Carbon and Impregnated Burned Basic Brick

SIGNIFICANCE AND USE
4.1 This practice defines a procedure that ensures reasonably consistent preparation of specimens for product testing and evaluation.  
4.2 This practice can be used in the laboratories of producers, users, and general interest parties for research and development or quality control work. It is particularly useful for interlaboratory comparisons on products, for repetitive evaluations or comparisons of products or product quality, and in specifying a uniform preparation practice for specimens for acceptance testing.  
4.3 If pitch-impregnated samples are prepared by wet cutting or drilling, care should be taken in drying them. If the samples are heated to facilitate drying, the temperature to which they are heated should not be so high that it causes drainage of pitch from the samples.  
4.4 Porosities of metal-containing brick must be measured using kerosene or mineral spirits, because using water will result in an artificially low result.
SCOPE
1.1 This practice covers a procedure for preparing test specimens from magnesia-carbon and impregnated burned basic brick. This practice generally concerns preparation of test specimens from brick greater than 13 in. (33 cm) in length. These brick are mainly manufactured for use in electric arc furnaces and basic oxygen furnaces.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Specification for Clay Roof Tiles

ABSTRACT
This specification covers clay roof tiles with such durability and appearance that can provide a weather-resistant surface of a specified design. Each tile should be manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to high-temperature firing. The heat treatment should develop a fired bond between material particles that provides the required strength and durability. The tiles should be shaped by molding, pressing, or extrusion during manufacture. Generally, the tiles are planar or undulating rectangular and are classified into three grades according to the degree of resistance to weathering. Materials are also grouped into three types according to profile and rise-to-width ratio. Colors and textures produced by application of inorganic coatings are allowed except when the coloring is done by flashing or the texturing by sanding where the sand does not form a continuous coating. Each tile should conform to the specified values of durability, freezing and thawing, transverse breaking strength, efflorescence, reactive particulates, and permeability.
SCOPE
1.1 This specification covers clay tiles intended for use as roof covering where durability and appearance are required to provide a weather-resistant surface of specified design.  
1.2 Tiles are manufactured from clay, shale, or similar naturally occurring earthy substances and subjected to heat treatment at elevated temperatures (firing). The heat treatment must develop a fired bond between the particulate constituents to provide the strength and durability requirements of this specification (see firing and fired bond in Terminology C1232).  
1.3 Tiles are shaped during manufacture by molding, pressing, or extrusion and it is permitted to use the shaping method to describe the tiles.  
1.4 Tiles are generally planar or undulating rectangular shapes available in a variety of cross-sectional profiles, shapes, sizes, surface textures, and colors.  
1.5 Three grades of tile having various degrees of resistance to weathering are covered in this specification. Three types of tile are defined to cover the features that influence appearance.  
1.6 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
