SIST EN 13473-2:2002

SIST EN 13473-2:2002 is the Slovenian national standard that adopts EN 13473-2:2001 from the European Committee for Standardization (CEN). It specifies the test methods and general requirements for multi-axial multi-ply fabrics used as reinforcement, so producers, laboratories, specifiers and buyers can check the same properties on the same basis.

What does SIST EN 13473-2:2002 specify?

SIST EN 13473-2:2002 covers two things: the test methods used to determine the properties named in Parts 1 and 3 of EN 13473, and the general product requirements for all multi-axial multi-ply fabrics within the Part 1 scope. In practice, it is the part you use when you need to measure, inspect and label these reinforcement fabrics consistently.

What are the key requirements of SIST EN 13473-2:2002?

SIST EN 13473-2:2002 turns the series into a practical checking document. It links each relevant property to a named test method, and it sets visual acceptance rules, packaging expectations and package marking needs.

Test methods and property selection

• Clause 4 and Table 1 link each property to a test method, including loss on ignition, size content, moisture content, filament diameter, mass per unit area, length and width, thickness, and mechanical properties of laminate.
• The document treats the list of physical properties as guidance for choosing which properties and limits belong in a technical specification. That matters because the fabric user can select only the properties that are relevant to the application.
• For laminate mechanical properties, EN ISO 527-4 is used, but comparisons between reinforcement textiles are only meaningful when the composite samples are made with the same reinforcement layout, the same resin type and the same processing. This prevents misleading comparisons between unlike test pieces.

Appearance and defect acceptance

• Clause 5.1 requires the fabric to be substantially free from contamination such as oil or dirt and to avoid unacceptable faults.
• The defect system uses major and minor defects with point scoring, and the overall acceptance level is limited. In practice, that gives suppliers and inspectors a common way to judge visual quality during receiving inspection or final release.
• The product specification may set alternative acceptance levels. That is important when a customer has stricter or different quality needs.

Packaging and labelling

• Clause 5.2 requires packaging that protects the product during handling, storage and transportation.
• Clause 5.3 lists the package information that has to be shown: designation code, total mass per unit area including ply construction and binding system, width, length, net package weight, defect designation, handling or storage instructions, and the manufacturer’s production and traceability reference.
• For users, this supports traceability, incoming checks and correct warehouse handling.

What terms does SIST EN 13473-2:2002 define?

SIST EN 13473-2:2002 uses terms from ISO 472 and EN 13473-1, and it relies on a few control terms in its requirements.

• Designation code - the identifying code used to name the fabric in EN 13473-1.
• Mass per unit area - the fabric weight related to its area, used for specification and receiving checks.
• Binding system - the construction element that holds the fabric plies together.
• Ply construction - the arrangement of the fabric plies and their yarn or thread directions.
• Major defect - a serious visual fault that counts more heavily in the defect scoring system.
• Minor defect - a smaller visual fault that still counts in the defect scoring system.
• Defect points - the scoring method used to total appearance defects for acceptance.

Who uses SIST EN 13473-2:2002?

SIST EN 13473-2:2002 is used by makers of reinforcement fabrics, test laboratories, composite processors, quality managers and buyers. It is also relevant to anyone specifying or checking materials for reinforced plastics and other composite reinforcement products, because it ties product definition to test methods and visual acceptance rules.

What changed in SIST EN 13473-2:2002 from the previous edition?

SIST EN 13473-2:2002 is the Slovenian adoption of EN 13473-2:2001. The document itself presents that European Standard as the referenced edition.

Which standards are used with SIST EN 13473-2:2002?

SIST EN 13473-2:2002 relies on EN 13473-1 for designation and on several ISO and EN ISO standards for measurement and vocabulary.

• EN 13473-1 - designation of multi-axial multi-ply fabrics.
• EN ISO 527-4 - tensile test conditions for fibre-reinforced plastic composites.
• EN ISO 3344 - moisture content of reinforcement products.
• EN ISO 10548 - size content of carbon fibre.
• ISO 472 - plastics vocabulary used for terms and definitions.
• ISO 1887 - loss on ignition for textile glass.
• ISO 1888 - average diameter of textile glass staple fibres or filaments.
• ISO 3374 - mass per unit area of mats and fabrics.
• ISO 4603 - thickness of woven fabrics.
• ISO 5025 - width and length of woven fabrics.
• ISO 11567 - filament diameter and cross-sectional area for carbon fibre.

What does the SIST EN 13473-2:2002 document contain?

SIST EN 13473-2:2002 contains the scope, referenced standards, terms and definitions, a list of physical properties with their test methods, and general requirements for appearance, packaging and labelling. Table 1 is the core reference for test methods, and Table 2 gives the defect classes and acceptance rules used for visual inspection. The bibliography points readers to related standards for tensile testing, sampling and material symbols.
