PD IEC PAS 63328-2020 PDF

Full title and description

STB PD IEC PAS 63328-2020 — Zhaga interface specification, Book 1 and Book 12. This Publicly Available Specification defines the common concepts and general requirements for Zhaga-compliant LED luminaire components (Book 1) and specifies mechanical and interface definitions for a set of rectangular LED Arrays with circular light-emitting surfaces (Book 12).

Abstract

IEC PAS 63328:2020 is a Zhaga interface specification published as a PAS that provides definitions and requirements to ensure mechanical and functional interoperability between LED arrays, holders and luminaires. It includes general concepts (Book 1) and specific mechanical definitions for certain rectangular LED Arrays (Book 12), intended to aid component interchangeability and simplify luminaire design. Note: the IEC record shows this PAS was withdrawn on 31 January 2025.

Scope

This PAS specifies common concepts for Zhaga interface specifications and general requirements for Zhaga‑compliant components (Book 1). Book 12 defines a family of rectangular LED Arrays with circular light‑emitting surfaces and the mechanical interface between those LED Arrays and their corresponding Holders; the mechanical interface between Holder and Luminaire (outline, optical cover aperture and mounting holes) is referenced to other Zhaga Books (e.g., Book‑10). The document is intended to support interoperability and facilitate replacement and assembly across components from different manufacturers.

Key topics and requirements

• Definitions and common concepts for Zhaga interface specifications (terminology, reference frames and interface classes).
• Mechanical and dimensional specifications for specified rectangular LED Arrays with circular light-emitting surfaces (Book 12).
• Requirements for mechanical interfaces between LED Array and Holder, and cross‑reference to Holder–Luminaire interfaces (Book‑10).
• General requirements to support interchangeability, mounting, alignment and basic mechanical compatibility of components.
• Guidance to manufacturers and luminaire designers to enable modular design and field‑replaceable LED components.

Typical use and users

Intended users include LED array and module manufacturers, holder and luminaire designers, lighting system integrators, test laboratories and standards/specification writers. The PAS is used to design mechanical interfaces that ensure parts from different suppliers can be assembled and replaced with predictable fit and alignment.

Related standards

This PAS is part of the Zhaga interface specification family and is related to other IEC/PD/ Zhaga books in the 6332x series (for example IEC PAS 63329 and other Zhaga Books covering Holder–Luminaire interfaces such as Book‑10). National PD/adoption documents (e.g., BSI PD IEC PAS 63328:2020) reproduce the IEC PAS text as a national publication. Users should check current Zhaga and IEC catalogues for any replacements, amendments or consolidated publications that may have superseded parts of this PAS.
