20、ization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establish
21、ed has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
22、 International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pu
23、blication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such paten
24、t rights. ISO 10352 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. This third edition cancels and replaces the second edition (ISO 10352:1997), which has been technically revised to make a distinction between materials which have bee
25、n manufactured using a solvent and those which have been manufactured without using a solvent, a different variant of the procedure being specified for each.

27、ional sheet, tape, fabric and mats. Unless stated to the contrary in the relevant material specification, this International Standard is applicable to prepregs in which any type of reinforcement (aramid, carbon, glass, etc.) and any type of matrix (thermosetting or thermoplastic) has been used. 2 No

30、are usually supplied in rolls or in packs of sheets. In this context, an individual roll or pack of sheets is an elementary unit. 3.2 laboratory sample sample taken from an elementary unit 3.3 test specimen specimen cut from a laboratory sample 4 Principle The mass of a test specimen of known area i
31、s determined. Two different specimen sizes are specified, depending on the type of material. If the material has been manufactured using a solvent or if the volatile-matter content of the material is not negligible, the sample is conditioned in a specified atmosphere before test specimens are taken.
32、 The result is expressed as the mass per unit area.

33、ype Ia and type Ib specimens, or graduated in milligrams and accurate to 5 mg for type IIa and type IIb specimens. 5.2 Square template, with the dimensions given in Table 1 for the material being tested, with a tolerance of 0,1 mm on the length of each side. 5.3 Ancillary items, such as a sharp cutt
34、ing tool and tweezers. 6 Conditioning and testing 6.1 Conditioning 6.1.1 Materials for which no conditioning is required Conditioning is not required for the following materials: those which are known to have been manufactured without using a solvent and to have been stored under conditions close to
35、 standard atmospheric conditions; those for which the volatile-matter content is known, from test data, to be negligible and which are known to have been stored under conditions close to standard atmospheric conditions; those for which the material specification states that no conditioning is requir
36、ed. After the laboratory sample has been cut from an elementary unit, the sample shall be covered with a plastic film. 6.1.2 Conditioning of material stored at ambient temperature With material which has been stored at ambient temperature, the laboratory sample cut from an elementary unit shall be c
37、onditioned in the same standard atmosphere as that which will be used for testing (see 6.2.1) for a minimum of 2 h, unless otherwise specified. The laboratory sample shall be kept covered with its protective films in a solvent-resistant bag. 6.1.3 Conditioning of material stored at below ambient tem
38、perature With material which has been stored at temperatures lower than ambient temperature, the material (generally an elementary unit), suitably packed in an airtight, solvent-resistant bag to prevent moisture pick-up, shall be allowed to reach ambient temperature over a period of time determined
39、by the mass of the package. This time shall not be less than 8 h, and the actual time shall be recorded in the test report. When the material has reached ambient temperature, the laboratory sample cut from the elementary unit shall be conditioned in the same standard atmosphere as that which will be
40、 used for testing (see 6.2.1) for a minimum of 2 h, unless otherwise specified. The laboratory sample shall be kept covered with its protective films in a solvent-resistant bag. 6.2 Testing 6.2.1 Test atmosphere The test shall be carried out in a standard atmosphere as specified in ISO 291.

42、he three categories of material described in 6.1.1. 6.2.2.2 Materials requiring conditioning After conditioning, the test shall be carried out within 6 h unless otherwise specified, the laboratory sample being kept in the same standard atmosphere as that which will be used for testing until the test
43、 is carried out (see 6.1.2 or 6.1.3). 7 Test specimens 7.1 Shape and dimensions The preferred test specimen shape is a square with the dimensions given in Table 1, which depend on the type of material. The various types of material given in Table 1 are defined as follows: Type Ia materials: relative
44、ly heavy materials, such as sheet moulding compounds, preimpregnated mats and woven prepregs, made without using a solvent. Type Ib materials: relatively heavy materials, such as sheet moulding compounds, preimpregnated mats and woven prepregs, made using a solvent. Type IIa materials: relatively li
45、ght materials, such as unidirectional prepregs (e.g. for aerospace use), made without using a solvent. Type IIb materials: relatively light materials, such as unidirectional prepregs (e.g. for aerospace use), made using a solvent. NOTE 1 A production method which uses a solvent is usually called a “
46、wet” method and a production method which does not use a solvent is usually called a “dry” method or “hot melt” method. NOTE 2 The designations type IIa and type IIb are usually used for relatively lightweight materials that require a more accurate determination. For special applications, rectangula
47、r specimens, round specimens or square specimens of dimensions different from those given in Table 1 may be used by agreement between the interested parties. The surface area of these specimens should preferably be between 0,04 m2and 0,10 m2for type Ia and type Ib materials and between 0,01 m2and 0,
48、04 m2for type IIa and type IIb materials.
