Overview

EN ISO 22553-9:2021 (ISO 22553-9:2020) defines a laboratory method to determine the volatile-matter content (stoving loss) of electro-deposition coatings (e-coats) during stoving. The standard is applicable to e-coats used in the automotive sector and other industrial products (chillers, radiators, consumer goods, aerospace, agriculture). It specifies test panels, apparatus, a repeatable procedure and the calculation for reporting stoving loss as a mass fraction (percent).

Key topics and technical requirements

Scope and purpose: Measure the mass loss of an e-coat during thermal curing (stoving) to quantify volatile content and reaction-related loss.

Test principle: Determine non-volatile matter after stoving; calculate stoving loss as (mass loss after stoving / mass of applied e-coat) × 100.

Apparatus & accuracy:

Laboratory deposition system with tank recirculation and DC supply
Analytical balance (accuracy 0.0001 g)
Oven capable of holding specified object temperature (±2 °C up to 150 °C; ±3.5 °C between 150–200 °C)
Thermometer (0.1 °C), timer, ammeter

Test panels: Electrically conductive, pre-treated panels per ISO 1514, approximately 190 mm × 105 mm × 0.75 mm.

Procedure:

Deposit e-coat in a controlled laboratory bath (temperature typically 25–35 °C)
Rinse, pre-dry (≈110 °C for ~60 min), weigh, then stove at the agreed object temperature and time
Carry out each determination in triplicate (mean or median may be used)

Evaluation & reporting:

Calculate stoving loss (%) from measured masses
Test report must include product ID, tank voltage/temperature, application and stoving times/temperatures, results, deviations and anomalies

Precision: No precision data is currently available in the document.

Practical applications and users

This standard is intended for:

Coating formulators evaluating solvent/volatile behavior during cure

Automotive and industrial QA/QC labs verifying e-coat specifications

R&D teams optimizing bake schedules and cure chemistry

Third‑party testing organizations and certification bodies Understanding stoving loss helps optimize cure cycles, ensure regulatory compliance for VOC/volatile content, and improve coating performance and cost-efficiency.
