ASTM D3643-15 某些碱溶性树脂的酸值的标准测试方法

4.1 This test method is not appropriate for alkali-soluble resins whose acid functionality is due to incorporated anhydrides. Variations in manufacture, storage, and possible contamination of anhydride functional resins may cause partial hydrolysis, or esterification, which will invalidate data from this test method. Anhydride functional resins should be characterized by Test Method D3644. 4.2 This test method is used to measure a property of acid functionalized resins. Acid number determines the utility of resins as well as being a significant quality control measure. 1.1 This test method covers the measurement of the free acidity present in certain alkali-soluble resins. 1.2 This test method is not suitable for styrene-maleic anhydride resins. 1.3 The resin manufacturer should specify whether or not this test method may be used for his product(s). 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.

GSO ISO 295:2015 塑料 热固性材料试样的压缩成型

This International Standard — establishes the general principles and lays down the procedure to prepare test specimens of heat- and pressure-moulded thermosetting material from different moulding compounds; — specifies the details for test specimen preparation to be included with the test reports on properties; — gives the general principles for the design of the mould intended for the preparation of the test specimens. The conditions required for preparing, in a reproducible manner, test specimens which will give comparable results are discussed relative to the substance under consideration. The method applies to phenolic resin, aminoplastic, melamine/phenol, epoxy and unsaturated-polyester based thermosetting powder moulding compounds (PMCs). Due to the nature of certain moulding compounds, their flow properties or other variable factors, it may be necessary to prepare the test specimens according to special methods. The latter are normally in an agreement between the interested parties and noted in the moulding report.

GSO ISO 60:2015 塑料 可以从指定漏斗中倒入的材料的表观密度的估计

This International Standard specifies a method of determining the apparent density, i.e. the mass per unit of volume, of loose material (powder or granular material) that can be poured from a funnel of specified design. NOTE — For a method of determining the apparent density of loose moulding material that cannot be poured from a specified funnel, see ISO 61. When the method is applied to relatively coarse materials, rather variable results may be obtained, owing to the error introduced when a straightedge blade is drawn across the top of the cylinder. A knowledge of apparent density is of limited value in estimating the relative fluffiness or bulk of moulding materials, unless their densities in the moulded condition are approximately the same.

GSO ISO 172:2015 塑料 模制品 苯酚甲醛 游离氨的检测

This International Standard specifies a qualitative method of detecting the presence of free ammonia or other volatile bases in phenol-formaldehyde mouldings by the exposure of an indicator paper to the vapour from a powdered sample. It may be used when the absence of free ammonia is a requirement.

GSO ISO 75-2:2015 塑料 负载变形温度的测定 第2部分：塑料和硬橡胶

This part of ISO 75 specifies three methods, using different values of constant flexural stress, which can be used for the determination of the temperature of deflection under load of plastics (including filled plastics and fibre-reinforced plastics in which the fibre length, prior to processing, is up to 7,5 mm) and ebonite: • — method A, using a flexural stress of 1,80 MPa; • — method B, using a flexural stress of 0,45 MPa; • — method C, using a flexural stress of 8,00 MPa. The standard deflection, Δs, used to determine the temperature of deflection under load corresponds to a flexural-strain increase, Δεf, defined in this part of ISO 75. The initial flexural strain due to the loading of the specimen at room temperature is neither specified nor measured in this part of ISO 75. The ratio of this flexural-strain increase to the initial flexural strain depends on the modulus of elasticity, at room temperature, of the material under test. This method is, therefore, only suitable for comparing the temperatures of deflection of materials with similar room-temperature elastic properties. NOTE 1 The methods give better reproducibility with amorphous plastics than with semi-crystalline ones. With some materials, it can be necessary to anneal the test specimens to obtain reliable results. Annealing procedures, if used, generally result in an increase in the temperature of deflection under load (see 6.6). NOTE 2 For additional information, see ISO 75-1:2013, Clause 1.

GSO ISO 120:2015 塑料 苯酚甲醛模具 游离氨和氨化合物的测定 比色比较法

This International Standard specifies a colorimetric comparison method for the semi-quantitative determination of the amount of ammonia in phenol-formaldehyde mouldings. NOTE — This International Standard does not provide an absolute measure of the ammonia present. The amount of ammonia in a moulded article is of importance when corrosion of metal inserts or contamination of foodstuffs in contact with the article has to be considered.

GSO ISO 2554:2015 塑料 不饱和聚酯树脂 羟值的测定

This International Standard specifies a method for determining the hydroxyl value of unsaturated polyester resins. In fact, this method determines the difference between the hydroxyl value and the acid value; it is therefore necessary to determine the total acid value separately, in order to calculate the hydroxyl value. NOTE 1 The hydroxyl value of saturated polyester resins (for example, polyester resin used for the manufacture of polyurethanes and polymeric plasticizers) and of certain types of alkyd resins may also be determined by this method.

GSO ISO 3001:2015 塑料 环氧化合物 环氧当量的测定

This International Standard specifies a method for the determination of the epoxy equivalent and is applicable to all epoxy compounds. In the case of epoxyamines, it is necessary to apply the modification specified in annex A.

Plastics -- Epoxy compounds -- Determination of epoxy equivalent

GSO ISO 308:2015 塑料 模压酚醛材料 丙酮可溶物的测定（未模压状态下材料的表观树脂含量）

This International Standard specifies a gravimetric method for the determination of the amount of matter that can be extracted by acetone, at a temperature near its boiling point, from a sample of finely divided phenolic moulding material. The method applies only to moulding materials based upon novolak resins and not to those based upon resols, as the latter type of resin may not be completely soluble in acetone. In this International Standard, the amount of acetone-soluble matter is reported as the apparent resin content because, although the extract consists mainly of phenolic resin and hexamine, other acetone-soluble components such as lubricants and colorants or natural resins from the filler are normally also present and will therefore be reported as resin.

GSO ISO 15028:2015 塑料 用于生产聚氨酯的芳香族异氰酸酯 分解氯的测定

This International Standard specifies a method for the determination of the hydrolysable-chlorine content of toluene-2,4-diisocyanate, toluene-2,6-diisocyanate or mixtures of the two. This test method may also be applied to other isocyanates of suitable solubility, such as crude or refined polymeric isocyanates.

GSO ISO 119:2015 塑料 苯酚甲醛模制品 游离酚的测定 碘量法

This International Standard specifies an iodometric method for the semi-quantitative determination of the amount of free phenols in phenol-formaldehyde mouldings. NOTE — This International Standard does not provide an absolute measure of the free phenols present. The amount of free phenols in a moulded article is influenced to a major extent by the degree of cure. Its evaluation is also of interest where the possibility of contamination of foodstuffs or other materials in contact with the article has to be considered.

GSO ISO 15063:2015 塑料 用于生产聚氨酯的多元醇 使用近红外光谱法测定羟值

This International Standard specifies a method for the determination of hydroxyl numbers of polyols using NIR (near-infrared) spectroscopy. Definitions and calibration techniques are given. Procedures for selecting calibration materials and for collecting and processing data to develop NIR calibrations are outlined. Criteria for building, evaluating and validating the NIR calibration model are also described. Procedures for sample handling, data gathering and evaluation are included. It is necessary to know the hydroxyl number of polyols in order to properly formulate polyurethane systems. This International Standard is suitable for use in research, quality control, specification testing and process control.

GSO ISO 14896:2015 塑料 聚氨酯原料 异氰酸酯含量的测定

This lnternational Standard specifies two methods for the measurement of the isocyanate content of aromatic isocyanates used as polyurethane raw materials. Method A is primarily applicable to refined toluene diisocyanate (TDI), methylene-bis-(4-phenylisocyanate) (MDI) and their prepolymers. Method B is applicable to refined, crude or modified isocyanates derived from toluene diisocyanate, methylene-bis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate. It can also be used for isomer mixtures of toluene diisocyanate, methylene-bis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate. Other aromatic isocyanates may be analysed by this method if precautions are taken to verify suitability. It is not applicable to blocked isocyanates.

GSO ISO 14897:2015 塑料 聚氨酯生产用多元醇 水含量的测定

This International Standard 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.

GSO ISO 75-3:2015 塑料 载荷变形温度的测定 第3部分：高强度热固性层压材料和长纤维增强塑料

This part of ISO 75 specifies a method for the determination of the temperature of deflection under load of high-strength thermosetting laminates and compression-moulded long-fibre-reinforced plastics in which the fibre length is greater than 7,5 mm. The flexural stress used is not fixed, as in ISO 75-2, but is a fraction (1/1 000) of the initial (room-temperature) flexural modulus of the material under test. This allows the method to be applied to materials with a wide range of flexural moduli. For additional information, see ISO 75-1:2004, clause 1.

GSO ISO 14848:2015 塑料 不饱和聚酯树脂 130°C反应性的测定

This International Standard specifies a method of measuring — the time required for the temperature of a solution of unsaturated-polyester resin and a catalyst, heated in a thermostatically controlled bath at 130 °C, to rise • from 80 °C to 140 °C, • from 80 °C to the maximum temperature reached; — the maximum temperature reached; — the speed of the reaction, determined by drawing a tangent at the point of inflection of the temperature/time curve. It applies in particular to unsaturated-polyester resins processed at a temperature higher than 100 °C. NOTE — The results are closely linked to the conditions. The aim of this International Standard is to define them as exactly as possible, particularly the following: a) The quantity and form of the resin sample being examined (test tube diameter, height of resin in the tube). b) The rate at which the sample is heated in the bath. For example, the use of a liquid having a relatively low heat capacity (ethylene glycol, silicone oil) leads to slower heating. c) The type of thermometer used. Thermometers having a response slower than that of a thermocouple, and resistance probes having too large a heat-sensitive element, are unsuitable. d) The position of the heat-sensitive element in the resin, both heightwise and relative to the axis of the test tube containing the resin. e) The nature of the catalyst.
