22、 each other by a classification system based on appropriate levels of the designatory properties a) temperature of deflection under load b) melt volume-flow rate c) Charpy notched impact strength d) flammability and on information about basic polymer parameters, intended application and/or method of
23、 processing, important properties, additives, colorants, fillers and reinforcing materials. 1.3 This part of ISO 28941 is applicable to all PPE materials, including those modified with polystyrene or polyamide or other materials. It applies to materials ready for normal use in the form of powder, gr
24、anules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. 1.4 It is not intended to imply that materials having the same designation necessarily have the same performance. This part of ISO 28941 does not provide engineering data, performance data or data on pro
25、cessing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified in ISO 15103-2, if suitable. 1.5 In order to specify a thermopla
26、stic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1).

33、doubling the separation sign, i.e. by two commas (,). 3.2 Data block 1 In this data block, after the hyphen, poly(phenylene ether) materials are identified by the symbol PPE, in accordance with ISO 1043-1, followed by a hyphen and a code-number giving additional information on the polymer, as specif

40、ct strength by a two-figure code-number (see 3.4.4) and the flammability by a combination of code-letters and code-numbers indicating the flammability category (see 3.4.5). The code-numbers are separated from each other by hyphens. If a property value falls on or near a range limit, the manufacturer
41、 shall state which range will designate the material. If subsequent individual test values lie on, or on either side of, the limit because of manufacturing tolerances, the designation is not affected. NOTE Not all combinations of the values of the designatory properties may be possible for currently
42、 available polymers. 3.4.2 Temperature of deflection under load The temperature of deflection under load shall be determined in accordance with ISO 15103-2. The possible values of the temperature of deflection under load at 1,8 MPa and 0,45 MPa are divided into 17 ranges, each represented by a lette
43、r followed by a three-figure code-number as specified in Table 3 and Table 4, respectively.

46、nce with ISO 15103-2. The measured value shall be rounded off to the nearest whole number and this whole number taken as the code-number. It will usually be a two-figure number. In cases when it is a single-figure number, the code-number shall be zero followed by the single-figure number. EXAMPLE If
47、 the measured melt volume-flow rate is 5,1 cm3/10 min, the code-number will be 05. 3.4.4 Charpy notched impact strength The Charpy notched impact strength shall be determined in accordance with ISO 15103-2. The possible values of the Charpy notched impact strength are divided into eight ranges, each
