This document specifies the dimensions and tolerances of female electrode caps for resistance spot welding of metallic materials. Taper dimensions and tolerances of the electrode caps follow the values specified in ISO 1089. NOTE Electrode caps with locking tapers are addressed in ISO 20168. Male electrode caps are specified in ISO 5830.

Abstract

Overview

Key topics and technical requirements

Scope and purpose: Specifies dimensions and tolerances for female electrode caps used in spot welding to ensure interchangeability and reliable performance.
Taper fits: Primary taper specified is 1:10, with taper dimensions and tolerances to follow ISO 1089. An alternative 1:9.6 taper is provided (Annex A) for market relevance.
Dimensions and tolerances: Standardizes a set of base cap types (A0, B0, C0, D0, D1, E0, F0, F1, G0) and common variations; tolerances and dimensional limits are provided in the document’s tables.
Materials: Electrode-cap materials shall conform to ISO 5182 (materials for electrodes and ancillary equipment).
Cooling design: Illustrations and guidance on water-cooling hole bottom profiles and hole depth options (Figure 2) highlight how geometry affects cooling efficiency and cap lifetime.
Mechanical limits: Informative tables give indicative maximum electrode force values for typical cap diameters and material hardness ranges (for guidance only).
Designation, labelling and marking: Prescribes a consistent designation string (e.g., ISO 5821–B0–16–20–40–8–30) and requirements for package labelling and individual cap marking to aid traceability.

Applications and who uses this standard

ISO 5821:2025 is intended for:

Welding equipment and electrode cap manufacturers - for design, production and quality control
Tooling and fixture designers - to select compatible caps and tapers
Automotive and metal-fabrication OEMs and suppliers - to ensure interchangeability and consistent welding performance
Procurement and quality assurance teams - for specifying parts and verifying conformity
Maintenance engineers - for correct replacement, identification and lifecycle management of electrode caps

Practical benefits include improved interchangeability, predictable cooling and force performance, and standardized marking for traceability.
