Full title and description

St ASTM D4247-99 (2004) — Standard Specification for General‑Purpose, Black Heavy‑Duty, and Black Extra‑Heavy‑Duty Crosslinked Polychloroprene Jackets for Wire and Cable. This short specification defines material and performance requirements for crosslinked polychloroprene (commonly known as neoprene) compounds intended for use as outer jackets on electrical cables for general, heavy‑duty and extra‑heavy‑duty service.

Abstract

This specification (designation D4247, original edition 1999, reapproved/recorded as D4247‑99(2004)) sets out the scope, terminology and basic physical/property requirements for crosslinked polychloroprene cable jackets. It includes limitations on use temperature, references applicable test methods, and identifies sampling and test procedures to verify compliance. The document was later withdrawn by ASTM in January 2006 and is retained as a historical standard.

General information

• Status: Withdrawn (administratively withdrawn by ASTM, January 2006; retained as historical).
• Publication date: Approved 10 April 1999 (designated D4247‑99); recorded/reapproved in 2004 as D4247‑99(2004).

• Number of pages: 2 pages (concise specification).

Scope

The standard covers crosslinked polychloroprene compounds suitable for use as outer coverings or jackets on electrical cables intended for general‑purpose, black heavy‑duty and black extra‑heavy‑duty service. It defines the intended application and a lower installation temperature limit (not recommended for installation below −25 °C) and points users to referenced test methods for verifying physical and aging properties.

Key topics and requirements

• Material: crosslinked polychloroprene (neoprene) compound formulation for cable jackets.
• Service classes: general‑purpose, heavy‑duty and extra‑heavy‑duty black jackets.
• Temperature limitation: not recommended for installation at temperatures lower than −25 °C.
• Physical/property tests: jacket must meet specified physical properties (referenced test methods apply for tensile, elongation, aging, etc.).
• Referenced test methods and sampling: testing according to applicable ASTM test methods for crosslinked insulations and jackets (for example Test Methods D470 and relevant terminology D1711).
• Units: primary values given in inch‑pound units; SI values may be provided for information.

Typical use and users

Intended users include cable and wire manufacturers, compound formulators, materials engineers, cable specification writers, procurement and quality control laboratories that manufacture or approve polychloroprene (neoprene) jackets for electrical and telecommunications cables in heavy‑duty applications.

Related standards

Commonly referenced or related ASTM documents include Test Methods D470 (Test Methods for Crosslinked Insulations and Jackets for Wire and Cable) and Terminology D1711.

FAQ

Q: What is this standard?

A: ASTM D4247‑99 (recorded as D4247‑99(2004)) is a short ASTM specification that defined requirements for crosslinked polychloroprene (neoprene) outer jackets for electrical cables intended for general‑purpose, heavy‑duty and extra‑heavy‑duty service.

Q: What does it cover?

A: It covers the material class (crosslinked polychloroprene) and basic service classification, calls out the recommended lower installation temperature (not below −25 °C), and refers to ASTM test methods for verifying physical and aging properties of the jacket material.

Q: Who typically uses it?

A: Cable manufacturers, material suppliers (compound producers), test laboratories, product engineers, and procurement/specification professionals who require standard criteria for neoprene jacketing on electrical cables.

Q: Is it current or superseded?

A: The document was originally approved in 1999 and carried the reapproval notation in 2004 (D4247‑99(2004)). ASTM administratively withdrew the designation in January 2006. It is therefore not an active/maintained ASTM standard; users should confirm current, applicable jacketing specifications or alternative material standards for new work.

Q: Is it part of a series?

A: It was issued under ASTM Committee D09 (Electrical and Electronic Insulating Materials) and related to other D09 jacketing and insulation specifications and test methods. Related jacket specifications for other polymer types (for example chlorosulfonated polyethylene) are published under separate D‑series designations.

Q: What are the key keywords?

A: Polychloroprene, neoprene, cable jacket, crosslinked jacket, heavy‑duty jacket, wire and cable, D4247, jacketing material.
