5.1 These test methods can be used for research or for quality control to determine the total chlorine content of aromatic isocyanates. In some instances total chlorine content may correlate with performance in polyurethane systems. 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 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 may have to be 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 and health practices and determine the applicability of regulatory limitations prior to use.Note 1—There is no known ISO equivalent to this standard.

NOTE 1 A variant of this method, applicable to solid phenolic resins, is described in annex A. With liquid resins having a viscosity greater than 2 Pas, it may be necessary to use this variant, which calls for a magnetic stirrer.

This International Standard specifies three methods for the determination of the hexamethylenetetramine (“hexa”) content of phenolic resins. The three methods are equivalent. The Kjeldahl method described in Clause 3 is not applicable if there are other components containing nitrogen in the phenolic resin. The perchloric acid method and the hydrochloric acid method described in Clause 4 and Clause 5, respectively, are only applicable if there are no other basic or acidic additives in the resin. If the resin contains additives which can be oxidized by perchloric acid, only the hydrochloric acid method (Clause 5) is applicable.

This part of ISO 15252 specifies the requirements for the physical and chemical properties of epoxy powder moulding compounds (EP-PMCs) and compression- or injection-moulded test specimens produced from them. It is limited to those powder moulding compounds whose composition and properties are significantly different. It is further limited to those moulding compounds which are of general technical and/or economic importance. The properties which are used to characterize the moulding compounds, the test methods and the test conditions are selected from those given in ISO 15252-2. The moulding compounds are divided into types according to their composition and properties. The various types are designated using the designation system defined in ISO 15252-1.

This International Standard specifies a method for the determination of the flow distance of powdered heat-setting phenolic resins for production and control. With reference to tablet formation, test temperature and angle of inclination of the glass plate, measurement of the flow distance involves arbitrarily defined conditions. 1.2 The flow distance is dependent on the reactivity and melt viscosity of the resins. Rapid solidification and high melt viscosity shorten the flow distance

This International Standard specifies a microtitration method to measure the degree of unsaturation in polyether polyols used in the production of polyurethanes. It is based on the reaction of mercuric acetate with double bonds in the polyol. It does not apply to compounds in which the unsaturation is conjugated with carbonyl, carboxyl or nitrile groups. The product being measured must be essentially dry and free of inorganic salts, especially halides.

This International Standard specifies a method for determining the gel time of phenolic resins at a given temperature, using automatic apparatus under specified conditions. The test temperatures are 100 “C, 130 “C and 150 “C. The method specified employs a plunger driven to carry out a reciprocating vertical motion. , This method applies to the following types of phenolic resin: - liquid resols - solid resols with low melting points Powdered resins with a short gel time, such as mixtures of novolak and hexamethylenetetramine, do not lend themselves to this type of determination. Such resins crosslink as soon as fusion starts and become too viscous in the test tube to give meaningful results. Resins containing large amounts of a solvent with a low boiling point are especially unsuitable for this type of determination. With such resins, a boiling and distillation process takes place as the resin hardens. It might be of interest to determine the time taken for the resin to gel in the presence of a catalyst. The catalyst shall be added in well defined proportions. The type of catalyst used and its treatment shall be stated in the test report.

This International Standard specifies a method for the determination of the mechanical, electrical, thermal and other properties of thermosetting moulding materials when tested under defined conditions at elevated temperatures. The method is used for the determination of the relative Performance temperature (RPT) of thermosetting moulding materials. This RPT is necessary in describing the short-term Performance of these materials at elevated temperatures. Coupled with the long-term property evaluations of polymeric materials, the RPT provides designers and engineers with a more complete picture of the expected Performance of materials in use at elevated temperatures.

This part of ISO 15252 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of epoxy powder moulding compounds (EP-PMCs). Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given here. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PMCs are listed. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, PMCs are also included in this part of ISO 15252, as are the designatory properties found in ISO 15252-1. In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

This International Standard is used to determine the total chlorine content of aromatic isocyanates used in the preparation of polyurethanes. The difference between the total chlorine content and the hydrolyzable chlorine content (see ISO 15028) is a measure of the process solvents left in the product. Both test methods are applicable to a variety of organic compounds, including aliphatic isocyanates, but the amount of sample used might need to be adjusted. These test methods can be used for research or for quality control. NOTE This International Standard is technically equivalent to ASTM D 4661-03.

1.1 The method specified in this International Standard measures the basic constituents in polyols that are soluble in glacial acetic acid and reactive with perchloric acid. Samples containing 0,3 % to 10 % of nitrogen have been evaluated by this method. The method is applicable to polyether polyols and polyether polyol blends that are used in polyurethane reactions. The results are measures of batch-to-batch uniformity and may be used to estimate reactivity in polyurethane reactions. 1.2 It is also permissible to express the results in equivalents of base per gram of sample. 1.3 This method is technically equivalent to that in ASTM D 6979-03.
