EN ISO 1346 Fibre Ropes - Polypropylene Split Film, Monofilament and Multifilament (PP2) and Polypropylene High Tensile Multifilament (PP3)

The standard "EN ISO 1346 Fibre ropes - Polypropylene split film, monofilament and multifilament (PP2) and polypropylene high tenacity multifilament (PP3) - 3, 4, 8 and 12-wire ropes", which has its basis in a European standard and was subsequently published by the International Organization for Standardization (ISO), specifies the requirements for 3-wire laid rope and 4-wire shroud laid ropes, 8-wire braided ropes and 12-wire braided ropes for general service made of polypropylene and gives the rules for their identification.

This standard does not cover all variations in strength or product performance. The rope manufacturer should be consulted to ensure that the intended design meets the requirements of the application.

For the purposes of this standard, the terms and definitions given in ISO 1968 apply. Minimum breaking strength is also the minimum strength that a fiber rope will exhibit when tested using a recognized procedure or test method. This strength is determined by each manufacturer using its own internal statistical methods based on breaking tests. The appendix to ISO 9554 provides two statistical methods for determining minimum breaking strength (Annex D).

Polypropylene ropes must be produced in one of the following constructions:

• Type A: 3-strand rope laid rope
• Type B: 4-strand shroud laid rope
• Type L: 8-strand braided rope
• Type T: 12-strand braided rope

Construction, manufacturing, installation, labeling, packaging, invoicing and delivery times must comply with the ISO 9554 standard.

In the EN ISO 1346 standard, the physical properties are specified as follows: The linear density and minimum breaking strength must comply with the tables titled "Linear density and minimum breaking strength of 3-wire rope-laid polypropylene ropes, type A" and "Linear density and minimum breaking strength of 4-wire shroud-laid polypropylene ropes, type B." The following applies to these tables.

• The reference number corresponds to the approximate diameter in millimetres.
• Linear density in kilotex corresponds to the net mass per length of rope expressed in grams per metre or kilograms per thousand metres.
• Linear density is under reference voltage and is measured as specified in the ISO 2307 standard.
• The breaking strengths stated in these tables relate to new dry and wet ropes.
• The strength determined by the test methods specified in ISO 2307 may not be an accurate indicator of the strength at which a rope would break under other conditions and circumstances. The type and quality of the termination ratio, the previous conditioning applied to the rope, and the application of force can significantly impact breaking strength. A rope twisted around a mast, winch, pulley, or sheave can break at a significantly lower force. A knot or other defect in a rope can significantly reduce breaking strength.

In short, the EN ISO 1346 standard is essential because it provides a standardized framework for plywood specifications, ensuring consistency, quality, and interoperability in plywood production, testing, and use across different regions and industries. The key reasons for considering this standard are:

• Quality assurance: This standard defines technical requirements for plywood, such as dimensions, binding quality and mechanical properties, and ensures that products meet consistent quality criteria for safety and performance.
• Cooperation and trade: By aligning with international standards and European norms, it facilitates trade and reduces disputes and compliance issues by ensuring that plywood produced in one country meets the expectations of buyers in another.
• Safety and reliability: Specifies test methods and performance criteria, ensuring the plywood is suitable for intended applications (e.g. construction, furniture or packaging) and reducing the risk of failure in structural or load-bearing uses.
• Compliance with environmental regulations and legislation: This standard often includes provisions for sustainable sourcing and production, helping manufacturers comply with environmental regulations and meet market demands for environmentally friendly materials.
• Consumer confidence: Standardization builds trust among consumers and industries by ensuring that plywood meets predefined criteria, making it easier to select appropriate materials for specific purposes.

Without this standard, variations in plywood quality, terminology, and performance can lead to confusion, inefficiency, and potential safety hazards in plywood-based industries. EN ISO 1346 provides a common language and reliable benchmarks for manufacturers, suppliers, and end users globally.

Fiber ropes are used in a wide variety of industries and applications because of their flexibility, strength-to-weight ratio, corrosion resistance and ease of use.

Our organization, which has been supporting businesses across all sectors for years through a wide range of testing, measurement, analysis, and evaluation activities, has a strong team of employees who closely follow global developments in science and technology and are constantly improving themselves. In this context, we also provide testing services in accordance with the EN ISO 1346 Fiber ropes - Polypropylene split film, monofilament, and multifilament (PP2) and polypropylene high-tenacity multifilament (PP3) - 3, 4, 8, and 12-strand ropes.
