BS IEC 62899-204-2019 PDF

Full title and description

STB BS IEC 62899-204-2019 — Printed electronics — Part 204: Materials — Insulator ink — Measurement methods of properties of insulator inks and printed insulating layers. This document defines terms and specifies standardized measurement methods for characterizing insulator (dielectric) inks and the printed insulating layers they form in printed-electronics applications.

Abstract

IEC 62899-204:2019 (adopted as BS IEC 62899-204:2019 and circulated under STB/BS naming in some catalogues) establishes terminology and test/measurement procedures to evaluate key electrical and physical properties of insulator inks and printed insulating layers used in printed electronics. Typical measurements covered include dielectric properties, breakdown strength, surface and volume resistivity, layer thickness and uniformity, adhesion and cure-related characteristics. The standard is part of the IEC 62899 printed‑electronics family developed by TC 119.

Scope

The document is applicable to insulator inks (including dielectric inks) and to insulating layers printed from those inks for use in printed‑electronics devices. It specifies terms and standard measurement methods for characterising electrical and physical properties of insulator inks and printed insulating layers — for example dielectric constant/permittivity, dielectric loss, breakdown voltage/strength, surface and volume resistivity, thickness/uniformity, and adhesion/cure characteristics — so that results are comparable between laboratories and manufacturers. The scope is limited to measurement and characterisation methods rather than prescriptive material compositions or performance limits.

Key topics and requirements

• Standardised terminology and definitions for insulator inks and printed insulating layers (to align test reporting across the 62899 series).
• Methods for measuring dielectric properties (permittivity, loss tangent) of printed insulating layers.
• Procedures for determining dielectric/breakdown strength and breakdown voltage of printed films.
• Surface and volume resistivity measurement techniques for insulating layers and inks.
• Thickness and uniformity measurement approaches for printed insulating films (including recommended instrumentation and sampling).
• Adhesion and mechanical integrity checks for printed insulating layers and associated test conditions (e.g., tape tests, peel tests where applicable).
• Guidance on sample preparation, conditioning and reporting to ensure repeatability and comparability of results across labs.

Typical use and users

Primary users include manufacturers and formulators of insulator/dielectric inks, printed‑electronics device developers and assemblers, independent test laboratories, research and development groups working on printed circuitry and dielectric layers, and standards or compliance teams requiring reproducible measurement procedures. National standards bodies and procurement specialists may also use the document when specifying test requirements or adopting the IEC text as a national/BS (or STB/BS) publication.

FAQ

Q: What is this standard?

A: It is IEC 62899‑204:2019 — a part of the IEC 62899 printed‑electronics family that specifies measurement methods and terminology for insulator inks and printed insulating layers. The IEC base publication date is 20 May 2019; it has been made available/adopted in national catalogues as BS IEC 62899‑204:2019 (and appears in some listings under STB/BS naming).

Q: What does it cover?

A: It covers standard methods to characterise electrical and physical properties of insulator inks and the printed insulating layers they form — for example dielectric/permittivity measurements, dielectric loss, breakdown strength, surface/volume resistivity, layer thickness and adhesion — and sets out sample preparation and reporting recommendations so results are comparable.

Q: Who typically uses it?

A: Ink formulators, printed‑electronics manufacturers, R&D teams, independent test labs, quality and compliance teams, and standards bodies adopting IEC texts for national use (e.g., BSI as BS IEC).

Q: Is it current or superseded?

A: As published in 2019 (Edition 1.0), the IEC record lists a stability date extending into 2028 — it is current as of the IEC webstore record. Users should check national adoption records (BSI or local standards bodies) for any later amendments or national forewords.

Q: Is it part of a series?

A: Yes — IEC 62899 is a multipart series covering printed‑electronics topics (terminology, substrate materials, conductive inks, measurement methods, quality assessment, etc.). IEC TC 119 is the responsible technical committee. Consult other IEC 62899 parts when specifying complementary test or material requirements.

Q: What are the key keywords?
