1.1 本试验方法旨在通过破坏性灰化程序测定塑料中的无机物含量。灰分水平0.01 % 本测试方法涵盖了以上内容。 1.2 这些灰化程序仅用于定量聚合物中的残余固体，不能用于定性鉴定灰分的单个化学成分。 1.3 本试验方法仅限于在900°C下稳定的材料（包括玻璃）。试验方法 2584美元 建议用于未知样品，以及可能需要考虑无机部分熔合的情况。 1.4 氟化聚合物和含卤化组分的聚合物未包括在这些程序中。 1.5 测定塑料中无机残留物的两个步骤如下: 1.5.1 程序A， 马弗炉技术 -对于5–50克样品。样品在马弗炉中灰化之前在燃烧器上燃烧。 1.5.2 程序B， 快速灰渣马弗炉技术 -2–10克样品。样品在马弗炉中点燃并灰化。 注1: 为了更有效地灰化，塑料样品应该是粉末或颗粒的形式。 注2: 该测试方法提供了特定树脂中特定填料的填料含量的一致结果。然而，该方法可能不能在所有情况下提供绝对填料含量。这包括填充CaCO的聚合物 3. 纳米粘土和炭黑。 注3: 程序B等同于ISO 3451/1-（E）方法A。 1.6 以国际单位表示的数值应视为标准。 1.7 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 参见第节 9 具体的预防说明。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 塑料灰化产生的无机残留物可能是抗粘连剂、填料、增强剂、催化剂残留物、着色剂等。每种残留物的定量是制造过程的重要变量。

1.1 This test method was developed to determine the inorganic content of plastics by destructive ashing procedures. Ash levels of 0.01 % or above are covered by this test method. 1.2 These ashing procedures are used only to quantify the residual solids in the polymer and can not be used to identify the individual chemical components of the ash, qualitatively. 1.3 This test method is limited to those materials (including glass) that are stable to 900°C. Test Method D2584 is recommended for unknown samples, and in instances where fusion of the inorganic portions may be of concern. 1.4 Fluorinated polymers and polymers containing halogenated components have not been included in these procedures. 1.5 Two procedures for determining the inorganic residue in plastics are listed as follows: 1.5.1 Procedure A, Muffle-Furnace Technique — For 5 – 50 gram samples. Samples are flamed over a burner prior to being ashed in a muffle furnace. 1.5.2 Procedure B, Rapid-Ash Muffle-Furnace Technique — For 2–10 gram samples. Samples are ignited and ashed in a muffle furnace. Note 1: For more efficient ashing, the plastic sample should be in the form of powder or pellet. Note 2: This test method provides consistent results of filler content for a specific filler in a specific resin. However, this method may not provide the absolute filler content in all cases. This includes polymers filled with CaCO 3 , nano clays, and Carbon Black. Note 3: Procedure B is equivalent to ISO 3451/1-(E), Method A. 1.6 The values stated in SI units are to be regarded as the standard. 1.7 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. See Section 9 for specific precautionary statements. 1.8 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. ====== Significance And Use ====== 5.1 Inorganic residues from plastics ashing may be antiblock, fillers, reinforcements, catalyst residues, colorants, etc. The quantitative amounts of each are important variables of the manufacturing process.
