Endorsement notice The text of ISO 10352:2010 has been approved by CEN as a EN ISO 10352:2010 without any modification. EN ISO 10352:2010 (E) DIN EN ISO 10352:2011-04 31 Scope This International St
22、andard specifies a method for the determination of the mass per unit area of sheet moulding compound and preimpregnated unidirectional sheet, tape, fabric and mats. Unless stated to the contrary in the relevant material specification, this International Standard is applicable to prepregs in which an
23、y type of reinforcement (aramid, carbon, glass, etc.) and any type of matrix (thermosetting or thermoplastic) has been used. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For und
24、ated references, the latest edition of the referenced document (including any amendments) applies. ISO 291, Plastics Standard atmospheres for conditioning and testing 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 elementary unit individual
25、sample roll or sheet which is intended for the measurement of mass per unit area using this International Standard NOTE Prepregs 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 a
26、n elementary unit 3.3 test specimen specimen cut from a laboratory sample 4 Principle The mass of a test specimen of known area is 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-matte
27、r content of the material is not negligible, the sample is conditioned in a specified atmosphere before test specimens are taken. The result is expressed as the mass per unit area. EN ISO 10352:2010 (E) DIN EN ISO 10352:2011-04 45 Apparatus 5.1 Balance, graduated in tenths of grams and accurate to 0
28、,5 g for type 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
29、sharp cutting 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 condition
30、s close to 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
31、 is required. 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
32、shall be conditioned 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 a
33、mbient temperature 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 d
34、etermined 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 whi
35、ch 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. 6.2 Testing 6.2.1 Test atmosphere The test shall be carried out in a standard atmosphere as specified in ISO 291
36、. EN ISO 10352:2010 (E) DIN EN ISO 10352:2011-04 56.2.2 Time interval between conditioning and testing 6.2.2.1 Materials not requiring conditioning There is no time-interval requirement for the three categories of material described in 6.1.1. 6.2.2.2 Materials requiring conditioning After conditioni
37、ng, 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 is carried out (see 6.1.2 or 6.1.3). 7 Test specimens 7.1 Shape and dimensions The preferred test specimen s
38、hape 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: relatively heavy materials, such as sheet moulding compounds, preimpregnated mats and woven prepregs, made without us
39、ing 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 light materials, such as unidirectional prepregs (e.g. for aerospace use), made without using a solvent. Type I
40、Ib 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 “wet” method and a production method which does not use a solvent is usually called a “dry” method or “hot mel
41、t” 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, rectangular specimens, round specimens or square specimens of dimensions different from those given in Table 1 may be u
42、sed 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 0,04 m2for type IIa and type IIb materials. Table 1 Preferred specimen sizes Type of material Description of ma

44、erial specification or agreed between the interested parties, three test specimens shall be taken. 7.3 Preparation Test specimens will usually be taken from the laboratory sample cut from an elementary unit comprising a roll or a pack of sheets. If necessary, taking into account the roll dimensions
45、and the number of sheets per pack, an agreement between the interested parties shall define either the size of the laboratory sample to be taken from each elementary unit or other information such as the number of specimens and their location within the laboratory sample. The specimens shall be take
46、n uniformly across the roll or sheet and cut perpendicularly to the edges of the sheet. The specimens shall be taken at least 50 mm away from the edges of the roll or sheet and from any folds or creases in the roll or sheet. In the case of an edge-trimmed roll or sheet without folds or creases, the
47、specimens may be taken from the edge of roll or sheet (see Figure 3). Typical cutting plans are shown in Figures 1, 2 and 3. NOTE In practice, the locations from which the specimens are taken will usually be specified by the material specification or be agreed between the interested parties. 8 Proce
48、dure 8.1 Materials made without using a solvent Cut the test specimens from each laboratory sample using the template (5.2) and a suitable cutting tool (see 5.3). To ensure consistency in the specimen dimensions, it is important that precise instructions concerning the cutting operation be given to the operator. After removing the protective film(s), weigh each specimen and record the mass (m0) to the nearest 0,1 g for type Ia materials or to the nearest 1 mg for type IIa materials. 8.2 Materials
