CEN/TC 249/SC 2 - Composites, reinforcements, prepregs

2010-09-27 EMA: Track changed according to ISO database: MINOR AMENDMENT!!!

ISO 1899:2009 specifies a method for the determination of the linear density of glass-fibre, carbon-fibre, aramid-fibre and any other reinforcement-fibre yarns.
It is applicable to all types of yarn, including single yarns, double and cabled yarns, textured yarns, rovings and staple-fibre yarns.

ISO 1890:2009 specifies a method for the determination of twist in yarns made from textile glass, carbon, aramid or any other reinforcement fibres.
The method applies to single yarns (one twist) and to folded or cabled yarns (two or more twists). For folded and cabled yarns, the method is generally applied only to the final twist step.
The International Standard is applicable to package-wound yarns. If the measurement is carried out on yarns taken from a beam (or warp) or from a fabric, the result is of an indicative nature only.
The method is not applicable to products made from staple fibres.

CMC - Modification to references in Table 3

This European Standard specifies a method for the preparation of specimens of compression moulding composites for determining the anisotropy induced by material flow.
It is applicable to all SMC/BMC and GMT/LFT composites, which are being moulded under defined moulding conditions as described in EN ISO 12115 and ISO 1268-9.

This part of EN 14598 specifies the methods of preparation of test specimens and the test methods to be used in
determining the properties of Sheet Moulding Compound (SMC) and Bulk Moulding Compound (BMC).
Requirements for handling test material and for conditioning both of the test material before moulding and of the
specimens before testing are found 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 SMCs and BMCs are listed.
The properties have been selected from the general test methods in EN ISO 10350-2, Plastics - Acquisition and
presentation of comparable single-point data - Part 2 Long-fibre-reinforced plastics. Other test methods in wide
use for or of particular significance to these compression and injection moulding materials are also included in this
part of EN 14598, as are the designatory properties found in Part 1: Designation.
In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and
conditioning, test-specimens with the dimensions and the test procedures specified herein. Values determined will
not necessarily be identical to those obtained using test-specimens of different dimensions or prepared using
different procedures.

This part of prEN 14598 specifies the requirements for physical and chemical properties of Sheet moulding Compounds (SMC) and Bulk Moulding Compound (BMC) and compression or injection moulded specimens. The selection in this part is limited to those materials the composition and properties of which are significantly different.
Furthermore the selection is limited to those materials which are of more general technical and / or economical importance.
The properties which are used for the characterization of the moulding compounds, the test methods and the test conditions are based on part 2 of this standard. The list of properties is selected, initially, from those general test methods found in ISO 10350-1, Plastics - Acquisition and presentation of comparable single-point data - Part 1 : Moulding materials.
The moulding compounds are divided into types corresponding to their composition and properties. The designation of the types of moulding compounds is based on part 1 "Designation" of this standard.

1.1   This part of prEN 14598 establishes a data block system for the designation of Sheet Moulding Compounds (SMC) and Bulk Moulding Compounds (BMC)

1.5   Whenever general requirement data in the part 3 of this International Standard need to be indicated, this data block system is also the basis for it.
1.6   To ensure that the meanings of codes remain unambiguous and to avoid conflicts within the system codes and abbreviations have to be coordinated with ISO/TC 61/SC 1.

ISO 9163:2005 specifies two methods for the determination of the tensile stress at break of an impregnated roving:
a reference method using test specimens produced with moulded epoxy tabs;a short method using test specimens with no tabs or simple cardboard or composite tabs.
The methods are applicable to both assembled (multistrand) and direct (multifilament) rovings; nevertheless the reference method may be used for various linear densities, but the short method is described for 1200 tex rovings only, which is the linear density that allows the roving to spread out most easily to give a flat tape.

This document defines a method for the determination of data suited to the assessment of the flowability and solidification of polypropylene based glass fibre mat reinforced thermoplastic moulding compounds (GMT) carried out with commonly applied moulding parameters.
The influence on moulding behaviour of both the individual components of the material and the moulding parameters may be determined by this method. It is suitable for quality control purposes as well as for the development of material formulations.
Depending on the objectives of the analysis, different elements of the procedure described in this document may be chosen.
This test method may be used for the production of a test plate suitable for the preparation of test specimens for the determination of materials properties.

This european standard specifies the general principles and procedures for the preparation of compression moulded test plates from fibre reinforced thermo- setting moulding compounds such as Sheet Moulding Compound (SMC), Bulk Moulding Compound (BMC) and Dough Moulding Compound (DMC). The purpose of this European Standard is to specify the preparation of flat test plates from which test specimens can be machined (for applicable test purposes see informative Annex A). Test plates are being manufactured to give representative results by the different test procedures using specimens machined out of these test plates.

This European Standard describes the designation system for yarns based on continuous filament textile glass (single yarns, folded yarns) and excludes textures yarns and yarns based on staple fibre, rovings and pre-impregnated yarns.

This International Standard specifies a method for determining the flexural properties of fibre-reinforced plastic composites under three-point (Method A) and four-point (Method B) loading. Standard test specimens are defined but parameters are included for alternative specimen sizes for use where appropriate. A range of testing speeds is included.

This International Standard specifies a procedure for determining the in-plane shear stress-shear strain, shear modulus and shear strength of fibre-reinforced plastic composites by the +/- 45° tension test method. The method is suitable f for use with the following materials: - thermoset and thermoplastic matrix laminates made from unidirectional layers and/or fabrics including unidirectional fabrics, with the fibres oriented at +/- 45° to the specimen axis. the lay-up shall be symmetrical and balanced about the specimen mid-plane.

This international standard specifies a procedure for determining the apparent interlaminar shear strength (ILSS) of fibre-reinforced plastic composites by the beam method.

This European Standard specifies a method to determine the moulding shrinkage of compression moulded test specimens of thermosetting materials. It applies only to materials which exhibit no post-shrinkage after moulding such as polyester SMC and BMC. Knowledge of the shrinkage of these thermosetting materials is necessary for the construction of moulds and for establishing the suitability of the moulding material to produce parts with accurate dimensions.

This European Standard specifies a method for the determination of the moisture content of reinfrocements products, such as continuous filament yarn, staple fibre yarn, rovings, chopped strands, mats, fabrics and other forms of reinforcements made form textile glass, carbon or aramid fibres.

1.1 This International Standard specifies two methods for determining compressive properties, in directions parallel
to the plane of lamination, of fibre-reinforced plastic composites.
1.2 The compressive properties are of interest for specifications and quality-control purposes.
1.3 Two loading methods and two types of specimen are described. They are:
  Method 1: provides shear loading of the specimen (gauge length unsupported).
  Method 2: provides end loading, or mixed loading, of the specimen (gauge length unsupported).
NOTE For tabbed specimens end-loaded using method 2, some load is transferred into the specimen gauge length by
shear through the tabs.
  Type A specimen: rectangular cross-section, fixed thickness, end-tabbed.
  Type B specimen: rectangular cross-section, range of thicknesses, untabbed or end-tabbed (two sizes
available).
Any combination of test method and specimen may be used, provided that the requirements of subclause 9.8 are
satisfied and that the specimen is representative of the material under test. These alternative test conditions will not
necessarily give the same result.
The type A specimen is the preferred specimen for unidirectionally reinforced materials tested in the fibre direction.
For other materials, the type A or B specimen may be used. The type B2 specimen is preferred for mat, fabric and
other multidirectionally reinforced materials.
1.4 The methods are suitable for fibre-reinforced thermoplastic and thermosetting plastic composites.
Unreinforced and particle-filled plastics, as well as those reinforced with short fibres (less than 1 mm in length), are
covered by ISO 604 (see bibliography).
1.5 The methods are performed using specimens which may be machined from a test panel made in accordance
with ISO 1268 or equivalent methods, or from finished or semi-finished products.
1.6 The methods specify required dimensions for the specimen. Tests which are carried out on specimens of other
dimensions, or on specimens which are prepared under different conditions, may produce results which are not
comparable. Other factors, such as the speed of testing, the support fixture used and the condition of the
specimens, can influence the results. Consequently, when comparative data are required, these factors must be
carefully controlled and recorded.
1.7 Fibre-reinforced plastics are usually anisotropic. It is therefore often useful to cut test specimens in at least the
two main directions of anisotropy, or in directions previously specified (for example a lengthwise direction
associated with the production process).

Gives two calcination methods for the determination of the textile-glass and mineral-filler content of glass-reinforced plastics. Method A is used for the determination of the textile-glass content when no mineral fillers are present; method B is used when both components are present. Replaces the first edition.
