These test methods are suitable for quality control, as specification tests, and for research. Side reactions that form unsaturated compounds in polypropylene oxides produce small amounts of polymers with only one hydroxyl group per chain. These unsaturated polymers lower functionality and molecular weight, while broadening the overall molecular-weight distribution.1.1 These test methods measure unsaturation in polyether polyols. (See Note 0.)1.1.1 Test Method A, High-Volume Reagent MethodUses about 50 mL of 0.1 M mercuric acetate reagent in methanol and 15 g or more of sample. These test methods use an indicator for colorimetric determination of an end point. It is recommended for polyols with low values (below 0.01 millequivalents per gram (meq/g)) of unsaturation where large sample sizes are required.1.1.2 Test Method B, Low-Volume Reagent MethodUses 2 mL of ca. 0.05 M mercuric acetate reagent in methanol and about 1 g of sample or less. These test methods use a potentiometric determination of an end point.This standard does not purport to address all of the safety concerns, if any, associated with its use.

ASTM D6267-05 高温条件下烃类树脂的表观粘度的试验方法

This test method is used to measure the apparent viscosity of hydrocarbon resins at elevated temperatures. Elevated temperature viscosity values of a hydrocarbon resin may be related to the properties of coatings, adhesives and the like, containing such a resin. For hydrocarbon resins, values of apparent viscosity will usually be a function of shear rate under the conditions of test. Although the viscometer described in this test method operates under conditions of relatively low shear rate, shear rate depends on the spindle and rotational speed selected for a determination; therefore, comparisons between apparent viscosity values should be made only for measurements made with similar viscometers under conditions of equivalent shear rate. Approximate shear rates using various spindles are shown in Table A1.1 in Annex A1 to this procedure.1.1 This test method covers the determination of the apparent viscosity of hydrocarbon resins having apparent viscosities up to 2 000 000 millipascal seconds (mPas) (Note 0) at temperatures up to 300C (572F).Note 0The SI unit of (dynamic) viscosity is the pascal second. The centipoise (cP) is one millipascal second (mPas) and is frequently used as a viscosity unit.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D5296-05 用高效粒度排除色谱法测定聚苯乙烯平均分子量和分子量分布的标准试验方法

General Utility8212;The molecular weight (MW) and molecular weight distribution (MWD) are fundamental characteristics of a polymer sample. They may be used for a wide variety of correlations for fundamental studies, processing, or product applications. For example, the observed MWD may be compared to one predicted from assumed kinetics or mechanisms for a polymerization reaction. Differences between the values will allow alteration of theory or experimental design. Similarly, the strength, melt flow, and other properties of a polymer sample may be dependent on MW and MWD. Determinations of MW and MWD are used for quality control of polymers. Limitations8212;Because of the need for specific calibration of the polymer type under study, and because of the specific nature of polymer/solvent/column-packing interactions, this test method is valid only for polystyrene and non-exclusion effects are to be avoided. However, many of the principles of the method may be applied in generating HPSEC methods for other polymer systems, for example, using the principles of universal calibration. (see Practice D 3016).1.1 This test method covers the determination of molecular weight (MW) averages and the distribution of molecular weights for linear, soluble polystyrene by liquid high-performance size-exclusion chromatography (HPSEC). This test method is not absolute and requires the use of commercially available narrow molecular weight distribution (MWD) polystyrene standards for calibration. This test method is applicable for samples containing molecular weight components that have elution volumes falling within the elution volume range defined by polystyrene standards (that is, molecular weights generally from 2000 to 2 000 000 gmol1).1.2 The HPSEC is differentiated from traditional size-exclusion chromatography SEC (also referred to as gel permeation chromatography (GPC)) in that the number of theoretical plates per metre with an HPSEC system is about ten times greater than that for traditional SEC (see Terminology D 883 and Practice D 3016). The HPSEC systems employ low-volume liquid chromatography components and columns packed with relatively small (generally 3 to 20 m) microporous particles. High-performance liquid chromatography instrumentation and automated data handling systems for data acquisition and processing are required.1.3 The values stated in SI units are to be regarded as the standard.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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D4226-05 硬质聚氯乙烯(PVC)建筑产品耐冲击性的标准试验方法

The impact strength values obtained on the flat sections of a building product profile are relevant only to the flat section that has been tested and these values do not necessarily indicate the impact resistance of the whole product, which is affected by the configuration of the profile (that is, corners, ribs, etc). Constant weight and variable height, employed in these test methods, allow the velocity of impact to vary and, therefore, by Procedure B, can determine the energy of ductile-to-brittle transition, which cannot be determined if a variable weight is dropped from a constant height. These test procedures have been found to be useful elements in rigid poly(vinyl chloride) (PVC) building product characterization. Compound qualification, finished product quality control, environmental and weatherability research and development studies, and fabrication tolerance prediction constitute useful applications. Choice of the specific impactor head configuration used is related to a variety of product attributes, such as specimen thickness and product toughness as well as abstract factors, such as the anticipated mode of failure in a specific application. The geometric uniqueness of the impactor head configurations prevents any comparison or correlation of testing results on samples tested with differing impactor head configurations. In general, the conical impactor, C.125, is useful to ensure failure of thicker specimens where the H.25 impactor caused no failure. Note 28212;Equivalent surface conditions are more likely to occur when specimens are prepared by compression molding or extrusion than by injection molding. When comparing different samples tested with the same impactor head configuration, impact resistance shall be permitted to be normalized for average specimen thickness over a reasonably broad range (for example, 1 to 3 mm).3 However, this should only be done when the surface conditions listed in 6.1 are essentially equivalent. FIG. 2 Impact Tester1.1 These test methods cover the determination of the energy required to crack or break rigid poly(vinyl chloride) (PVC) plastic sheeting and profile flat sections used in building products, as well as extruded or molded test samples, under specified conditions of impact from a freefalling standard weight striking an impactor with either of two configurations in contact with the specimen.1.2 Two test procedures are included:1.2.1 Procedure A, used to determine minimum impact energy required to cause failure (hole, crack, split, shatter, or tear).1.2.2 Procedure B, used to determine minimum impact energy required to cause brittle failure.1.3 The values in inch-pound units are to be regarded as the standard.Note 18212;There is no similar or equivalent ISO standard.1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding, those in tables in figures) shall not be considered as requirements of this standard.1.5This 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 and health practices and determine the applicability of regulatory limitations prior to use.
