Steel cord conveyor belts - Determination of the lateral and vertical displacement of steel cords

This European Standard specifies methods for the determination of the mean lateral displacement between cords, and for the determination of the vertical displacement of cords relative to a mean level of steel cords within a conveyor belt as described in prEN ISO 15236-1.

Overview

EN 13827:2003 (CEN) defines standardized measurement methods for the lateral and vertical displacement of steel cords within steel-cord conveyor belts. The standard aligns with prEN ISO 15236-1 and provides practical procedures, required apparatus and reporting items to support consistent measurement, tolerance verification and quality control across manufacturing and inspection activities.

This standard is intended for conveyor belt manufacturers, testing laboratories, quality engineers and design teams who require repeatable methods for assessing cord pitch, supported belt width and cord height variations.

Key Topics

• Scope and purpose: Methods for determination of mean lateral displacement between cords and vertical displacement relative to a mean cord level.
• Apparatus: Typical tools specified include a measuring tape (graduated 1.0 mm), hand-held optical magnifier with 0.1 mm scale (≥ x8), and a dial gauge micrometer (0.1 mm divisions). A flat horizontal support surface is required to lay out full-width test pieces.
• Test piece requirements: Full belt width sample, not less than 50 mm long, with clean cut edges exposing cords for measurement.
• Method A (lateral measurements): Determination of mean cord pitch (tm) by measuring distance across cords, measuring cord diameter (d) and counting number of cords (n). Calculation of supported belt width (bt) and percentage deviation of actual supported width are included. Control sections of consecutive pitches (e.g., 21 cords or multiples of 20 pitches) are measured to assess pitch uniformity.
• Method B (vertical measurements): Measurement of mean cord height (hm) using a flat datum (uniform cover down). At evenly spaced intervals a number of cords equal to 10% of the total are measured to compute hm. Displaced cords are identified and grouped by severity levels (Dh1, Dh2, Dh3) based on deviations (categories use ±1.0 mm and ±1.5 mm thresholds as reporting bands).
• Test report contents: The standard specifies required report items including reference to EN 13827, belt identification, mean cord pitch, supported width deviation, individual pitch deviations, Dh percentages and test date.

Applications

• Quality control: Routine checks on production belts for cord alignment and uniformity.
• Incoming inspection: Acceptance testing of supplied belts against manufacturer tolerances.
• Design verification: Confirming cord geometry and pitch for proper performance in conveyor systems.
• Failure analysis: Identifying cord displacement patterns that may contribute to belt tracking or mechanical issues.

Related Standards

• prEN ISO 15236-1: referenced for design, dimensions and mechanical requirements of steel cord conveyor belts.
• Relevant CEN/TC 188 publications on conveyor belt testing and specification.

For practical implementation, use the specified apparatus and test-piece preparation methods in EN 13827:2003 to ensure repeatable, traceable measurements for production control and diagnostic testing of steel cord conveyor belts.
