Описание (английский):

IEC 63522-1:2025 is used for testing along with the appropriate severities and conditions for measurements and tests designed to assess the ability of specimens to perform under expected conditions of transportation, storage, and all aspects of operational use. The object of this test is to define a standard test method for the visual inspection and check of dimensions.

Overview

IEC 63522-1:2025 - Electrical relays: Tests and measurements - Part 1: Visual inspection and check of dimensions defines a standardized, reproducible method for visually inspecting relays and verifying their key dimensions. Published by the IEC in 2025, this part of the IEC 63522 series is intended to assess a relay’s mechanical integrity, marking and dimensional conformity under expected conditions of transportation, storage and operational use. It is primarily a non-destructive testing procedure unless the product standard requires internal inspection.

Key topics and requirements

Scope & purpose

Ensure relay marking, terminal identification and dimensions conform to product specifications.
Detect visible mechanical defects and document findings.

Inspection levels

Initial inspection: marking, terminal ID, housing (colour) and mechanical defects.
Visual inspection: outside-only checks for deformation, abrasion or other defects.
Detailed inspection: internal examination when required by the product standard (may involve careful opening).

Dimensional checks

Outline dimensions: conformity with drawings and detail specifications.
Clearance and creepage: verified per relay specification and IEC 63522-41 (insulation coordination); includes contact gap and barrier thickness where applicable.
Detailed dimensions & gauging: component-level checks and use of gauges when specified.

Measurement methods & equipment

Acceptable tools include vernier gauges, micrometres, callipers, measuring projectors, microscopes, CT/X‑ray scanning and CAD evaluation combined with CT data for complex insulation geometry.

Conditions to specify

Optical method, ambient lighting and special devices (e.g., polarized light), measurement magnification, gauging details and any deviations from standard methods.

Reporting

Test report should enable reproducibility and record specimen description, methods, visual observations and dimensional results.

Applications and users

IEC 63522-1:2025 is used by:

Relay manufacturers for production and final inspections

Third‑party test laboratories and certification bodies

OEMs and system integrators for incoming inspection and design verification

Quality, compliance and procurement teams for supplier audits and acceptance testing

R&D and failure‑analysis engineers for mechanical diagnosis and validation

Typical applications include routine production checks, pre‑shipment inspections, design verification (clearance/creepage checks) and documentation for conformity assessment.
