Full title and description

St ISO TR 6741-4-1987 — Textiles — Fibres and yarns — Determination of commercial mass of consignments — Part 4: Values used for the commercial allowances and the commercial moisture regains. This technical report provides the reference values (expressed in tables) commonly used for commercial allowances and commercial moisture regains when calculating the commercial mass of consignments of textile fibres and yarns.

Abstract

This part of ISO 6741 (published as a Technical Report) lists values for commercial allowances and commercial moisture regains that are intended to be agreed between interested parties and used with the ISO 6741 procedures for calculation of commercial mass. The values are given in two tables for the relevant generic fibre and yarn forms.

Scope

Specifies the standard reference values to be used as commercial allowances and commercial moisture regains for calculating the commercial mass of consignments of textile fibres and yarns when parties choose to apply the procedures of the ISO 6741 series. The report supplies those tabulated values only — its figures are intended to be formally agreed between the contracting parties and used together with the measurement and sampling procedures given in the other parts of ISO 6741.

Key topics and requirements

• Commercial allowances: recommended numerical allowances to account for packing, handling, or other commercial factors when reporting consignment mass.
• Commercial moisture regain: tabulated moisture‑regain percentages for common fibre and yarn types to convert between conditioned/dry mass and commercial (as‑supplied) mass.
• Application constraint: values are advisory and intended to be agreed between parties; they apply only when used with ISO 6741 series procedures.
• Format: the report presents the values in two concise tables keyed to fibre/yarn generic types and forms.

Typical use and users

Used by textile manufacturers, yarn producers, traders, commercial laboratories, inspection and testing bodies, quality managers and contract negotiators involved in buying/selling consignments of fibres and yarns where conversion between laboratory (dry/conditioned) mass and commercial invoiced mass is required. The tables serve as a common reference for contractual mass adjustments and for laboratory reporting when ISO 6741 sampling and measurement procedures are applied.

Related standards

Part of the ISO 6741 series (see ISO 6741‑1: mass determination and calculations; ISO 6741‑2: methods for obtaining laboratory samples; ISO 6741‑3: specimen cleaning procedures). The technical report (part 4) has been withdrawn; national bodies have produced related national adoptions and replacement publications in their catalogues (e.g., national listings showing SS‑ISO/TR 6741‑4 and notes of replacement by national ISO 6348 adoptions). A later ISO work item to revise part 4 was registered but subsequently abandoned.

FAQ

Q: What is this standard?

A: ISO/TR 6741‑4:1987 is a Technical Report in the ISO 6741 series that lists reference values for commercial allowances and commercial moisture regains used when calculating the commercial mass of consignments of fibres and yarns. It is a non‑normative report of tabulated reference figures intended for agreement between parties.

Q: What does it cover?

A: It provides two tables of values — (1) commercial allowances and (2) commercial moisture regains — applicable when the ISO 6741 procedures for sampling and mass calculation are used. The values are advisory and are to be agreed by the contracting parties.

Q: Who typically uses it?

A: Textile producers, yarn merchants, inspection and testing laboratories, quality and contract managers, and any party performing commercial mass calculations or negotiating mass‑related contract terms for consignments of fibres and yarns.

Q: Is it current or superseded?

A: ISO records show ISO/TR 6741‑4:1987 as withdrawn/annulled. Attempts to revise or replace the part at ISO level were registered as work items but were later abandoned; some national bodies show that the subject has been handled by related national ISO adoptions or other standards (consult national standards bodies for the currently accepted national practice).

Q: Is it part of a series?

A: Yes — it belongs to the ISO 6741 series (parts 1–4). Relevant companion documents are ISO 6741‑1 (mass determination and calculations), ISO 6741‑2 (sample preparation), and ISO 6741‑3 (specimen cleaning procedures). Users applying part 4 should use it together with the procedures in the other parts.

Q: What are the key keywords?

A: commercial allowances; commercial moisture regain; commercial mass; textile fibres; yarns; consignment mass; ISO 6741.
