ISO 10243-1991 rus PDF

Full title and description

ISO 10243:1991 — Tools for pressing — Compression springs with rectangular section — Housing dimensions and colour coding. This International Standard specifies housing (installation) dimensions and a colour‑coding system for compression springs made from rectangular wire; Russian‑language PDF editions (labelled "rus") are available from commercial distributors.

Abstract

The standard lays down the technical specifications for compression springs manufactured from rectangular wire when they are mounted (installed). It classifies springs by spring rate (light, medium, strong, extra‑strong) and defines the associated housing dimensions, tolerances, required force per unit deflection and a colour code for each class. It does not specify spring material, wire cross‑section, life expectancy or general product quality.

General information

• Publication date: 1991‑08 (first edition; published 28 August 1991 in many catalogues).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 01.070 (Colour coding); 25.120.10 (Forging equipment, presses, shears).
• Edition / version: Edition 1 (1991). Revised later by ISO 10243:2010.
• Number of pages: 17 (English edition PDF listing).

Scope

Specifies installation (housing) dimensions, tolerance limits, and a colour‑coding scheme for compression springs with rectangular cross‑section used in press tooling. Applies to springs as mounted; it does not attempt to prescribe spring material, wire section size, manufacturing quality or fatigue life. The standard is primarily focused on interchangeability and identification in tooling assemblies.

Key topics and requirements

• Classification of compression springs by spring rate: light, medium, strong, extra‑strong.
• Defined colour codes for each spring‑rate class to support quick identification in press tooling.
• Housing (installation) dimensions and related tolerances for mounted springs.
• Tables of required force to produce a specified deflection and maximum operating deflection limits for given diameters.
• Notes clarifying that the standard covers mounted‑state parameters only and does not replace material or endurance specifications for springs.

Typical use and users

Used by press tool designers, die and tooling manufacturers, spring suppliers, maintenance engineers in stamping/pressing operations, and purchasers specifying replacement springs or tool components. It supports interchangeability, maintenance, and safe selection of compression springs in tooling applications.

National adoptions/identical standards include DIN ISO 10243 (German adoption) and related national catalogs (e.g., BS adoptions). Commercial distributors may offer language variants (English, French, German, Russian) as separate PDF products.

FAQ

Q: What is this standard?

A: ISO 10243:1991 is an International Standard that defines housing dimensions, tolerances and a colour‑coding scheme for compression springs with rectangular cross‑section used in press tooling.

Q: What does it cover?

A: It covers mounted (installed) parameters of rectangular‑wire compression springs: classification by spring rate, required force per deflection, maximum operating deflection, housing dimensions and a standard colour code. It does not specify materials, wire cross‑section sizes beyond mounted dimensions, nor endurance or quality tests.

Q: Who typically uses it?

A: Tool and die engineers, press manufacturers, spring suppliers, maintenance personnel in stamping and pressing industries, and procurement/specification writers selecting replacement springs.

Q: Is it current or superseded?

A: The 1991 edition has been withdrawn and was revised by ISO 10243:2010; users should consult the 2010 revision for the current normative content.

Q: Is it part of a series?

A: It is a stand‑alone ISO standard within the tooling/pressing family (work of ISO/TC 29/SC 8) and is associated with national adoptions (e.g., DIN ISO 10243). The subject is also cross‑referenced in lists of ISO standards in the 10000–11999 range.

Q: What are the key keywords?

A: Compression springs, rectangular wire, housing dimensions, colour code, spring rate, press tooling, ISO 10243.
