ISO 3368-1975 PDF

Full title and description

Coated abrasives — Cloth rolls up to and including 40 mm width — Designation and dimensions. ISO 3368:1975 specifies the designation system and the nominal dimensional requirements for cloth‑backed coated abrasive rolls whose widths do not exceed 40 mm, to ensure consistent identification and interchangeability in production and procurement.

Abstract

This 1975 International Standard defines the names, designation elements and the principal dimensions (widths, core diameters, lengths and tolerances) applicable to cloth‑backed coated abrasive rolls up to 40 mm wide. It was prepared to harmonize product description and ordering across manufacturers and users of narrow abrasive rolls. The standard has since been withdrawn and its subject matter incorporated into later, consolidated standards for abrasive rolls.

Scope

ISO 3368:1975 applies to cloth‑backed coated abrasive rolls of nominal widths up to and including 40 mm. It covers the recommended designation (naming convention) and the dimensional parameters required for manufacture, supply and identification (e.g., nominal width groups, core diameters and nominal lengths with tolerances). It does not cover rolls wider than 40 mm, nor does it specify abrasive grain types, backing grades beyond “cloth”, or performance test methods. The subject was later consolidated into broader abrasive‑roll standards.

Key topics and requirements

• Designation system for cloth abrasive rolls (how to indicate width, length and core size in product identification).
• Nominal width categories and the limit “up to and including 40 mm”.
• Core (mandrel) diameter recommendations for small‑width rolls.
• Nominal roll lengths and acceptable manufacturing tolerances.
• Labelling and marking information to be provided with supply (identification and packaging).
• Notes indicating that wider rolls and other backings are covered by related standards (see Related standards).

Typical use and users

Primary users include manufacturers of coated abrasives, converters who slit wider rolls into narrow rolls, distributors and purchasers specifying small‑width abrasive rolls for hand or machine sanding, and quality/inspection personnel ensuring deliveries meet dimensional designation and ordering descriptions. Standards committees and technical libraries also reference the standard for historical/product classification purposes.

Related standards

ISO 3368:1975 was later withdrawn and the topic of abrasive rolls was consolidated into ISO 3366 (Coated abrasives — Abrasive rolls) and other related ISO documents covering rolls of different widths and backing types. Other adjacent standards address roll widths greater than 40 mm and test/performance methods for coated abrasives.

FAQ

Q: What is this standard?

A: ISO 3368:1975 is an International Standard that defined the designation and dimensional requirements for cloth‑backed coated abrasive rolls up to 40 mm width (published in 1975).

Q: What does it cover?

A: It covers the naming/designation elements and the principal dimensions (nominal widths, core diameters, lengths and tolerances) applicable to cloth‑backed coated abrasive rolls whose widths do not exceed 40 mm. It does not address abrasive grain specifications or performance testing.

Q: Who typically uses it?

A: Manufacturers, converters, distributors, procurement specialists and quality inspectors in the abrasives and surface‑finishing industries, plus standards librarians and technical committees referencing product designation schemes.

Q: Is it current or superseded?

A: It has been withdrawn. The subject matter was incorporated into later/wider standards for abrasive rolls (for example, ISO 3366 and related documents), so users should refer to the current ISO abrasive‑roll standards rather than ISO 3368:1975 for up‑to‑date requirements.

Q: Is it part of a series?

A: Yes — ISO 3368:1975 formed part of a set of ISO documents dealing with coated abrasive rolls and their designation/dimensions; other related standards address rolls of different widths, backing types and consolidated requirements (see ISO 3366 and adjacent ISO documents on coated abrasives).

Q: What are the key keywords?

A: Coated abrasives; cloth rolls; narrow abrasive rolls; roll designation; roll dimensions; core diameter; ISO 3368; abrasive standards.
