GB/T 4617-1984 酚醛模塑制品丙酮可溶物的测定

本标准规定了用丙酮在其沸点附近从磨细的酚醛模塑制品试样中，测定可抽提物数量的重量法。丙酮可溶物试验是一种测定由酚醛模塑料制成酚醛模塑制品相对固化度的方法。抽提过程应在指定条件下，于规定时间内进行。虽然测定了可溶物的大部分，但抽提作用不一定完全，其结果仅是一个比较的结果，因为抽提物常常含有未固化树脂以外的物质（如润滑剂、着色剂和增塑剂）。

GB/T 4616-1984 酚醛模塑料丙酮可溶物(未模塑态材料的表观树脂含量)的测定

本标准规定了能用丙酮在其沸点附近从颗粒的酚醛模塑料中，测定抽提物数量的重量法。 本方法仅适用于以线型酚醛树脂为基材的模塑料，而不适用于以甲阶酚醛树脂为基材的模塑料， 因为后一类的树脂不能完全溶于丙酮。

BS ISO 14897:2023 塑料 用于生产聚氨酯的多元醇 水分含量的测定

1   Scope This document specifies methods used to measure the water content of polyols employed as polyurethane raw materials. Method A is a manual amperometric method which has been included to better define the principles of the Karl Fischer measurement. Amperometric methods are applicable to a wide range of polyols , including those which have enough colour to obscure a visual end-point. Method B includes an automated amperometric procedure and an automated coulometric procedure. The coulometric procedure is an absolute method that does not require calibration and gives improved sensitivity compared with amperometric methods.

ASTM D4895-18(2023) 分散生产的聚四氟乙烯（PTFE）树脂的标准规范

1.1 This specification2 covers polytetrafluoroethylene (PTFE) prepared by coagulation of a dispersion. These PTFE resins are homopolymers of tetrafluoroethylene or modified homopolymers containing not more than 1 % by weight of other fluoromonomers. The materials covered herein do not include mixtures of PTFE with additives such as colors, fillers, or plasticizers; nor do they include reprocessed or reground resin or any fabricated articles because the properties of such materials have been irreversibly changed when they were fibrillated or sintered. 1.2 The values stated in SI units as detailed in IEEE/ASTM SI-10 are to be regarded as standard. The values given in parentheses are for information only. 1.3 The following safety hazards caveat pertains only to the Specimen Preparation Section, Section 9, and the Test Methods Section, Section 10, of this specification: 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 Warning note in 9.1.1 for a specific hazards statement. NOTE 1—Information in this specification is technically equivalent to related information in ISO 20568-1 and ISO 20568-2. 1.4 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 D7750-23 用封装样品流变仪通过动态机械程序测定热固性树脂固化性能的标准试验方法

1.1 This method covers the use of dynamic mechanical instrumentation for determination and reporting of the thermal advancement of cure behavior of thermosetting resin on an inert filler or fiber in a laboratory. It may also be used for determining the cure properties of resins without fillers or fibers. These encapsulated specimens are deformed in torsional shear using dynamic mechanical methods. 1.2 This method is intended to provide means for determining the cure behavior of thermosetting resins on fibers over a range of temperatures from room temperature to 250 °C by forced-constant amplitude techniques (in accordance with Practice D4065). Plots of complex modulus, complex viscosity, and damping ratio or tan delta as a function of time or temperature, or both, quantify the thermal advancement or cure characteristics of a resin or a resin on filler or fiber. 1.3 Test data obtained by this method is relevant and appropriate for optimizing cure cycles. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4.1 Exception—The Fahrenheit temperature measurement in 10.1 is provided for information only and is 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 Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5629-23 聚氨酯原料的标准试验方法:低酸度芳香异氰酸酯和聚氨酯预聚物中酸度的测定

1.1 This test method measures the acidity, expressed as ppm of hydrochloric acid (HCl), in aromatic isocyanate or polyurethane prepolymer samples of below 100 ppm acidity. The test method is applicable to products derived from toluene diisocyanate and methylene di(phenylisocyanate) (see Note 1). Refer to Test Method D6099 for determination of acidity in moderateto high-acidity aromatic isocyanates. 1.2 The values stated in SI units are to be regarded as the 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. NOTE 1—This standard is equivalent to ISO 14898, Method B. 1.4 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 D4661-23 聚氨酯原料的标准试验方法:异氰酸酯中总氯的测定

1.1 These test methods determine the total chlorine content of aromatic isocyanates used as polyurethane raw materials. The difference between the total chlorine content and the hydrolyzable chlorine content (see Test Method D4663) is a measure of the amount of chlorobenzene, o-dichlorobenzene, and other ring-substituted chlorinated products that are present. Both procedures are applicable to a variety of organic compounds but the amount of sample used is varied. (See Note 1.) 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. NOTE 1—This standard is identical to ISO 26603. 1.4 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.
