Full title and description

STB BS EN 13966-1:2003 — Determination of the transfer efficiency of atomising and spraying equipment for liquid coating materials - Part 1: Flat panels. This European laboratory standard specifies reproducible test procedures to measure the transfer efficiency (percentage of coating solids deposited on a flat panel versus solids delivered by the spray device) for a wide range of spray technologies (air-atomising, HVLP, LVLP, airless, air-assisted airless, rotary/bell atomisers, etc.).

Abstract

This standard defines two laboratory methods for determining transfer efficiency when applying liquid coating materials to flat test panels, specifies sample and test-rig requirements, environmental and measurement conditions, required material property measurements (solids content, density, viscosity), repeatability rules and reporting forms. It is intended to provide comparable, repeatable measurements for manufacturers, test laboratories, applicators and specifiers.

Scope

This Part 1 applies to laboratory determination of transfer efficiency for application of liquid coating materials onto flat panels. It covers a broad set of atomising/spraying equipment (conventional air atomisers, HVLP, LVLP, airless, air-assisted airless, rotary/bell atomisers) and defines test rig configuration, environmental controls, measurement methods and reporting to enable reproducible comparison between devices. A planned Part 2 was intended to cover other substrate geometries and electrostatically assisted equipment.

Key topics and requirements

• Definition and calculation of transfer efficiency (coating solids on panel ÷ solids delivered by device).
• Two specified determination methods (direct gravimetric measurement of delivered mass and indirect flow-derived measurement).
• Test-rig layout, background panels and test sheets, controlled stroke/speed and atomiser-to-panel distance.
• Requirements for measuring and reporting coating material properties (solids content, viscosity, density) and environmental conditions (temperature, humidity, pressure).
• Repeatability, number of runs and statistical treatment (minimum repetitions, mean reporting, criteria for repeating tests).
• Test report form and annexes giving calculation examples, tolerances and measurement guidance.

Typical use and users

Used by spray-equipment manufacturers (R&D and production), independent test laboratories, coating formulators, industrial applicators (automotive, aerospace, industrial finishing), procurement/specification engineers and regulatory bodies assessing application efficiency, overspray reduction and comparative performance of application technologies.

Related standards

Standards referenced or commonly associated with EN 13966-1 include safety and application equipment standards (for example EN 1953 series on atomising and spraying equipment safety, and other CEN product/safety standards for coating application and booths). National adoptions (BS EN, SS-EN, NEN-EN, etc.) provide the text in respective jurisdictions and occasional minor pagination differences.

FAQ

Q: What is this standard?

A: A CEN/EN laboratory test standard (adopted nationally as BS EN 13966-1:2003) that specifies how to measure the transfer efficiency of atomising and spraying equipment when applying liquid coatings to flat panels.

Q: What does it cover?

A: Test methods, rig and panel specifications, measurement and environmental requirements, data recording and reporting for calculating transfer efficiency; it covers many common spray technologies used in industry.

Q: Who typically uses it?

A: Equipment manufacturers, independent testing labs, applicators, coating formulators and procurement/specification engineers who need reproducible comparisons of spray application efficiency.

Q: Is it current or superseded?

A: The EN text was published in 2003 and national adoptions (including the BS version) remain available; a corrigendum was published in 2007. National bodies should be consulted for the latest legal/status information in a given country.

Q: Is it part of a series?

A: Yes — it is Part 1 (flat panels) and the committee envisaged additional parts (e.g., methods for other geometries and electrostatically assisted application). Users should check CEN committee outputs for any later parts or replacements.
