Specular Gloss of Nonmetallic Specimens: ASTM D523-89 Standard Test Method in PDF Format



<h1>What You Need to Know About ASTM D523-89 PDF Download</h1>


<p>If you are looking for a reliable and accurate method to measure the specular gloss of nonmetallic specimens, you may want to consider downloading the ASTM D523-89 PDF document. This document is a standard test method issued by the ASTM International, a global organization that develops and publishes voluntary consensus standards for various materials, products, systems, and services.</p>

<p>Specular gloss is a property of a surface that reflects more light in some directions than in others. The directions associated with mirror-like reflection usually have the highest reflectances. Specular gloss is important for evaluating the appearance and quality of many products, such as paints, coatings, plastics, ceramics, paper, textiles, and metals.</p>


<p>The ASTM D523-89 PDF document covers the measurement of the specular gloss of nonmetallic specimens for three different glossmeter geometries: 60, 20, and 85 degrees. These angles correspond to different levels of glossiness: the 60-degree geometry is used for most specimens and for determining when the 20-degree geometry may be more suitable; the 20-degree geometry is used for comparing specimens with high gloss values (above 70); and the 85-degree geometry is used for comparing specimens with low gloss values (below 10).</p>

<ol>


<li>What is the difference between specular gloss and reflection haze?</li>


<p>Specular gloss is a measure of how much light is reflected in the mirror direction from a surface, while reflection haze is a measure of how much light is scattered in other directions from a surface. Specular gloss and reflection haze are related but not equivalent properties. A surface can have high specular gloss but also high reflection haze, or low specular gloss but also low reflection haze, or any combination of these.</p>


<li>How can I check the validity and authenticity of the ASTM D523-89 PDF document that I downloaded?</li>


<p>You can check the validity and authenticity of the ASTM D523-89 PDF document by verifying its source, date, and content.
