AS 1334.7-1982 (2016) PDF

Full title and description

AS 1334.7-1982 — Methods of testing conveyor and elevator belting, Part 7: Determination of ply adhesion of conveyor belting. This document specifies a laboratory test method for measuring the ply adhesion (inter‑ply bond strength) of textile-reinforced conveyor belting and references related full‑thickness tensile test methods (AS 1334.3).

Abstract

This standard gives the principle, apparatus, specimen preparation, conditioning, test procedure, expression of results and reporting requirements for determining ply adhesion of conveyor belting. It is a short procedural standard intended to ensure repeatable measurement of interlaminar bond strength for quality control and comparative testing.

• Edition / version: 2nd edition (AS 1334.7-1982) — reconfirmed in 2016 (R2016).
• Number of pages: 1 (short procedural standard; some distributors list it as 1–2 pages).

Scope

This standard sets out a laboratory method for determining the ply adhesion (the bond between the plies) of textile‑reinforced conveyor belting. It is intended for use in testing belts for manufacture, acceptance testing and comparative evaluation. The method requires reference to AS 1334.3 for related tensile/elongation determinations.

Key topics and requirements

• Definition of ply adhesion and test principle (peel/separation type measurement).
• Apparatus and fixtures appropriate for thin, flexible belt specimens.
• Specimen preparation and size, including conditioning periods and atmospheres before testing.
• Step‑by‑step test procedure, including test speed and measurement method for bond strength.
• Expression of results (bond strength units, reporting of averages and individual values).
• Reporting requirements and references to related tests (notably AS 1334.3 — full thickness tensile strength and elongation).

Typical use and users

Used by conveyor belt manufacturers, test laboratories, materials quality control personnel, mining and bulk‑handling equipment purchasers, and engineering specifications groups. Typical applications are production quality control, vendor acceptance testing, and forensic or failure analysis where ply delamination is a concern.

Related standards

Commonly referenced or companion documents include other parts of AS 1334 (e.g., AS 1334.3 — Determination of full thickness tensile strength and elongation) and AS 1332/AS 1333 series for conveyor belting specifications. Internationally, related ISO test methods for conveyor belts (e.g., ISO test methods for ply/laminate adhesion and tensile testing) are relevant for comparison.

FAQ

Q: What is this standard?

A: AS 1334.7-1982 (Part 7 of the AS 1334 series) is an Australian Standards procedure that specifies how to measure the ply (inter‑ply) adhesion of textile‑reinforced conveyor belting in the laboratory.

Q: What does it cover?

A: It covers the principle, apparatus, specimen preparation and conditioning, test procedure, expression of results and reporting for ply adhesion testing; it is intended for use alongside related belt tests such as full‑thickness tensile testing (AS 1334.3).

Q: Who typically uses it?

A: Manufacturers, independent test laboratories, procurement/specification engineers in mining and bulk handling, and maintenance/quality teams concerned with belt integrity and delamination issues.

Q: Is it current or superseded?

A: The 1982 second edition remains current and was formally reconfirmed in 2016 (R2016). The reconfirmation was approved in January 2016 and published as reconfirmation notice in May 2016. Users should check referenced documents for more recent amendments.

Q: Is it part of a series?

A: Yes — it is Part 7 of the AS 1334 series (Methods of testing conveyor and elevator belting) and is normally used together with other parts (for example AS 1334.2, AS 1334.3, AS 1334.4, AS 1334.8, etc.) that specify other physical tests for conveyor belts.

Q: What are the key keywords?

A: Ply adhesion, conveyor belting, interply bond, AS 1334, belt testing, specimen conditioning, peel test, quality control.
