ISO 1181-1973 rus PDF

Full title and description

St ISO 1181-1973 rus — Three- or four-strand manila and sisal ropes. Original international standard specifying essential characteristics, designation rules and required tolerances for 3‑strand and 4‑strand manila (abaca) and sisal fibre ropes (first edition, 1973).

Abstract

This standard defines the main characteristics and tolerances for three‑ and four‑strand manila and sisal ropes with net mass per metre from 50 to 6 500 g and nominal diameters from 8 mm to 96 mm inclusive; it fixes minimum numbers of yarns per strand (based on a reference yarn linear density) and gives rules for designation and marking. Test methods are referenced (for example ISO 2307).

Scope

Applies to three‑strand and four‑strand manila and sisal ropes for general service whose net mass per metre lies between 50 g/m and 6 500 g/m and whose nominal diameters are between 8 mm and 96 mm inclusive. The standard sets minimum yarn counts per strand (based on a reference yarn linear density of 4 600 tex) and includes notes on dressing/lubricant amounts and designation rules.

Key topics and requirements

• Definition and classification of 3‑strand (laid) and 4‑strand ropes (shroud/laid) made from manila (abaca) and sisal fibres.
• Mandatory ranges for net mass per metre and nominal diameters (50–6 500 g/m; 8–96 mm).
• Minimum number of yarns per strand calculated from a reference yarn linear density (4 600 tex) and proportional adjustment rules if finer yarns are used.
• Specified tolerances and tabulated characteristic values for rope sizes and construction.
• References to test methods (for example ISO 2307 for determination of certain physical and mechanical properties).
• Rules for designation, marking and basic packaging/handling notes (including typical lubricant/dressing guidance).

Typical use and users

Used historically by rope manufacturers, quality and test laboratories, procurement and specification engineers in maritime, fishing, agricultural and general‑service industries where natural‑fibre ropes (manila/abaca and sisal) are specified. Also of interest to standards bodies, technical libraries and translators (Russian-language editions/records exist for archival or national distribution).

Related standards

Related and referenced documents include ISO 2307 (Fibre ropes — Determination of certain physical and mechanical properties) and definitions given in related ISO work such as ISO 1968. The 1973 edition was later revised by ISO 1181:1990 and then by ISO 1181:2004 (current consolidated edition for manila and sisal fibre ropes).

FAQ

Q: What is this standard?

A: ISO 1181:1973 is the first edition international standard that specified essential characteristics, classification and designation rules for three‑ and four‑strand manila (abaca) and sisal ropes.

Q: What does it cover?

A: It covers nominal diameters (8–96 mm), net mass per metre (50–6 500 g/m), minimum yarn counts per strand (based on 4 600 tex reference yarn), tolerances, designation and references to test methods (e.g., ISO 2307).

Q: Who typically uses it?

A: Rope manufacturers, procurement/specification engineers, maritime and fishing sectors, test laboratories and standards/archives — especially when working with or referencing natural‑fibre (manila/sisal) ropes.

Q: Is it current or superseded?

A: The 1973 edition is withdrawn and has been superseded by later editions — notably ISO 1181:1990 and the consolidated ISO 1181:2004 (the latter being the confirmed edition covering 3‑, 4‑ and 8‑strand constructions). Users should refer to the 2004 edition for the current international requirements.

Q: Is it part of a series?

A: Yes — ISO 1181 belongs to a family of rope standards managed by ISO/TC 38 (Textiles) and is used together with test and related standards such as ISO 2307 and other rope‑related ISO documents.

Q: What are the key keywords?

A: manila, abaca, sisal, fibre ropes, 3‑strand, 4‑strand, rope specification, designation, ISO 1181, natural fibre ropes.
