Full title and description

ASTM F1740-25 — Standard Guide for Inspection of Nylon, Polyester, or Nylon/Polyester Blend, or Both Kernmantle Rope. This guide provides recommended procedures for managing, inspecting, and determining the serviceability of kernmantle rescue ropes used by rescue and emergency-service personnel.

Abstract

ASTM F1740-25 is a concise (3-page) guide intended to help qualified, experienced personnel develop and apply inspection procedures—including rope-log review, visual inspection, and tactile examination—to decide whether a nylon, polyester, or nylon/polyester kernmantle rope may be returned to service. It emphasizes subjective evaluation by trained inspectors, record keeping, and user-defined retirement criteria rather than prescriptive numeric pass/fail limits.

Scope

This guide covers procedures to assist in the management, care, and inspection of nylon, polyester, or nylon/polyester blend kernmantle ropes used by rescue personnel. It provides guidance for establishing inspection procedures (rope-log review, visual and tactile inspection) to determine whether used rescue ropes should be placed into or returned to service, and notes that other user-specific factors may need to be considered. The guide does not approve any specific rope type nor address every possible safety concern.

Key topics and requirements

• Rope-log and documentation review (manufacture date, service history, prior incidents).
• Visual inspection criteria: sheath abrasion, cuts, discoloration, heat or chemical damage, sheath slippage, visible core exposure.
• Tactile inspection: detection of soft spots, core collapse, changes in diameter or stiffness, internal damage felt by running rope through gloved hands.
• Retirement and removal-from-service indicators and recommended conservative disposition practices.
• Requirement that inspections be performed by personnel deemed “qualified” and “experienced” by the user; need for training and documented inspection procedures.
• Emphasis on user-defined policies—this guide informs procedures but does not replace manufacturer instructions or regulatory requirements.

Typical use and users

Primary users include fire and rescue departments, technical rescue teams, search-and-rescue organizations, industrial rescue/rope-access teams, equipment managers, and safety officers. The guide is intended for experienced inspectors responsible for rope maintenance programs who must decide whether ropes can remain in service or require retirement. Manufacturers and training organizations may also use the guide to inform user instructions and inspection training.

Related standards

Standards commonly referenced alongside F1740-25 include NFPA standards for life-safety rope and rescue operations (historically NFPA 1983; content consolidated into NFPA 2500 in recent NFPA consolidation actions), ASTM specifications for life-safety and low-stretch kernmantle rope such as ASTM F2116 (low-stretch/static kernmantle life-safety rope), and international test-method standards for rope properties (for example ISO 2307 for certain physical and mechanical rope tests). Older / previous editions of ASTM F1740 (e.g., F1740-96 and subsequent reaffirmations/revisions) are the historical basis for the current guide.

FAQ

Q: What is this standard?

A: ASTM F1740-25 is a short guide published by ASTM International that gives recommended procedures for inspecting nylon, polyester, or blended kernmantle ropes used in rescue operations to determine serviceability.

Q: What does it cover?

A: It covers rope-log review, visual and tactile inspection techniques, indicators of damage (abrasion, cuts, heat/chemical exposure, sheath/core damage), and guidance on establishing user-specific criteria for retirement and record-keeping. It is not a prescriptive test standard or specification of minimum breaking strengths.

Q: Who typically uses it?

A: Fire and rescue services, technical rescue teams, rope-access and industrial rescue programs, equipment managers, manufacturers (for user guidance), and training organizations that maintain or inspect kernmantle rescue ropes.

Q: Is it current or superseded?

A: As of the 2025 designation it is an active ASTM guide (F1740-25). Users should confirm the latest status or any work items/revisions with ASTM if they need the absolute current administrative status.

Q: Is it part of a series?

A: F1740 is part of ASTM Committee F32 activity addressing rope and cordage topics; it complements other ASTM rope-related specifications (for example F2116 for low-stretch/static life safety rope) and sits alongside national/international standards and industry certification schemes for life-safety rope.

Q: What are the key keywords?

A: kernmantle, inspection, rope log, nylon, polyester, rescue, tactile inspection, visual inspection, retirement, life-safety rope.
