Описание (английский):

ISO 4230:2016 is a supplement to ISO 2568 and ISO 4231 and specifies the dimensions of hand- and machine-operated circular screwing dies intended for production of taper pipe threads, R series, in accordance with ISO 7‑1. With the exception of the die 1/16, the general dimensions of these dies (diameter, thickness and fixing dimensions) are in accordance with ISO 2568 so as to permit the driving of hand-operated dies with the aid of the die stocks defined in that document.

Overview

ISO 4230:2016 is an International Standard that supplements ISO 2568 and ISO 4231. It specifies the dimensions and marking requirements for hand- and machine-operated circular screwing dies used to produce R‑series taper pipe threads in accordance with ISO 7‑1. The standard is intended to ensure dimensional consistency and interchangeability of dies and die stocks across manufacturers.

Key editorial points in the 2016 (third) edition include the addition of an informative Annex A (mapping to ISO 13399) and a Bibliography. The document also notes that, except for the 1/16 die, general dimensions (diameter, thickness, fixing dimensions) conform to ISO 2568 to permit use with the die stocks defined there.

Key Topics

Scope and purpose: Defines geometry and marking rules for R‑series taper pipe thread dies to align with ISO 7‑1.

Dimensions: General dimensions are shown in the standard’s figures and tables. The document specifies which dimensions are to be standardized and which may be left to manufacturer discretion (for example, V‑groove, diameter D and clearance holes).

Tolerances:

Precision screwing dies: tolerances on D (f10) and on E (js12).
Non‑precision screwing dies: tolerances on D and E are left to the manufacturer’s discretion.

Thread lead: The thread lead of the screwing die is calculated on the basis of two threads (as noted in the standard).

Marking: Dies shall be marked with the letter R immediately followed by the thread designation (for example: R 3/4). Where tools comply fully with relevant standards, the ISO symbol may be appended at manufacturer discretion.

Data mapping: Annex A provides a relationship between the designations used in ISO 4230 and preferred symbols in ISO 13399, supporting digital data exchange and tooling databases.

Applications

Manufacturing and procurement of hand‑ and machine‑operated circular screwing dies for plumbing, piping, and hydraulic assemblies using R‑series taper threads.

Tooling specification and selection where compatibility with existing ISO 2568 die stocks is required.

Quality control and inspection processes to verify compliance with specified dimensions and tolerances.

Integration into tooling data systems and CAD/CAM libraries via the normative link to ISO 13399 symbol mappings.
