Overview
ISO 8130-14:2019 - "Coating powders - Part 14: Vocabulary" is an international standard that defines specialized terms used in the field of coating powders and powder coating. This second edition (2019) replaces the 2004 edition and focuses on consistent, industry-wide vocabulary for materials, processes, testing descriptors and storage/handling concepts. It complements general paint and varnish terminology given in ISO 4618 and other parts of the ISO 8130 series.
Key topics
This vocabulary standard provides clear definitions for terms commonly used in powder coating technology, including:
- Material and particle descriptors: particle size, particle size distribution, fines, oversize, particle strength, agglomeration, compaction
- Application and process terms: electrostatic powder spraying, tribo-charging, electrostatic fluidized bed, Faraday cage effect, impact fusion
- Flow and handling: pourability, powder flow rate, powder blocking, sieve blinding, pourability (of a coating powder)
- Thermal and cure behavior: melt flow, gelation, gel time, hybrid coating powder
- Performance and efficiency: deposition efficiency, reclaimed powder, incompatibility
- Storage and safety: shelf life, storage stability, lower explosion limit, back ionization
The 2019 revision renames and clarifies several entries (for example, “electrostatic spraying” to electrostatic powder spraying), introduces new terms such as particle strength, sieve blinding and shelf life, and updates cross-references within the ISO 8130 series.
Practical applications
ISO 8130-14:2019 is primarily a reference tool that improves communication and reduces ambiguity across the powder coating value chain. Typical uses include:
- Ensuring consistent terminology in technical specifications, test reports and product data sheets for powder coating and coating powders
- Supporting R&D and formulation work where precise definitions (e.g., particle size distribution, melt flow, gel time) are needed
- Guiding quality assurance and test laboratories when reporting results for powder characterization
- Helping procurement, compliance and regulatory documentation to use harmonized terms for storage, shelf life and safety (e.g., lower explosion limit, storage stability)
- Assisting standards writers and educators to align teaching materials and internal standards with ISO language
Related standards
- ISO 4618 - Paints and varnishes - Terms and definitions (general terms)
- Other parts of the ISO 8130 series (e.g., ISO 8130-13 for particle size analysis by laser diffraction)
ISO 8130-14:2019 is a concise, authoritative resource for anyone needing consistent, industry-accepted vocabulary in powder coating manufacturing, testing and specification.
