Key Safety and Quality Standards for Paint Coating Equipment and Liquids

The paint and coatings industry is rapidly evolving as businesses confront increasing demands for efficiency, safety, and product consistency. To thrive in a competitive global marketplace, companies must implement robust standards across every facet of their operations. This article delves into two vital international standards—SIST EN 1953:2025 and SIST EN ISO 19403-3:2025—offering businesses and professionals a comprehensive overview of requirements and best practices for paint coating equipment safety and the determination of surface tension in coating materials.

Internationally recognized standards in paint technology aren’t just checkboxes for compliance—they are essential building blocks for scaling productivity, enhancing worker safety, and sustaining long-term quality. By embracing the latest requirements for equipment and material testing, organizations gain a competitive edge, minimize operational risks, and position themselves for sustainable growth.

Overview / Introduction

The paint and coatings sector encompasses a broad array of applications, from industrial manufacturing lines and automotive finishes to architectural projects and high-tech electronics. Central to this industry’s reliability are the processes and equipment that apply paints, varnishes, and coatings—and the materials themselves. The right standards ensure that each stage, from equipment operation to laboratory material testing, meets stringent safety, environmental, and performance requirements.

Why are standards so indispensable?

• They guarantee safety: Preventing accidents and hazardous exposures is critical in environments dealing with chemicals and pressurized systems.
• They promote quality: Uniform methods for measuring surface tension (wettability) and operational procedures reduce variability.
• They enable scalability: With harmonized processes, businesses can streamline training, maintenance, and quality assurance at any scale.
• They ensure compliance: Meeting legal and regulatory needs not only avoids costly penalties, but also builds trust with customers and partners.

In this article, you’ll learn:

• The purpose, scope, and requirements of SIST EN 1953:2025 and SIST EN ISO 19403-3:2025
• How these standards impact paint coating operations and materials testing
• Steps for successful implementation and compliance approaches
• Practical benefits and risk mitigation through standard adoption

SIST EN 1953:2025 - Comprehensive Safety for Application Equipment

Application Equipment for Coating Materials – Safety

SIST EN 1953:2025 establishes a thorough framework for the safe design, construction, and operation of both hand-held and automatic equipment used for applying paint, powder, or other coating materials. This standard is essential for any business that utilizes pressurized equipment for the application of coatings in industrial settings.

Standard Scope and What It Covers

This standard addresses all significant hazards that may arise from using paint application equipment. Its requirements are valid when equipment is used as intended, as well as under reasonably foreseeable misuse. It carefully outlines procedures and design elements that reduce the risks of mechanical, electrical, thermal, and chemical hazards associated with coating processes.

Key areas include:

• Mechanical safety: Equipment must be capable of withstanding operational and accidental stresses without failure.
• Prevention of fluid release: Systems must minimize the risk of hazardous ejection of fluids or parts.
• Electrical safety: Standards for high-voltage and electrostatic applications ensure protection against fire and explosion.
• Thermal protection: Preventing burns from hot surfaces through insulation and temperature limits.
• Noise and ergonomics: Efforts to limit operator exposure to harmful noise and ergonomic risks.
• Explosion risk management: Addresses static and electrical discharge hazards in explosive environments.
• Instruction and marking: Comprehensive documentation and markings for safe installation, operation, and maintenance.

Exclusions

Certain equipment is outside the scope, such as:

• Systems operating above specific pneumatic or hydraulic pressures
• Non-atomizing machinery (like dispensers or extruders)
• Fine-art airbrushes
• Supply hoses and unrelated coating material delivery systems

Who Should Comply?

• Paint application system manufacturers (including automated and hand-held device producers)
• Industrial operators and integrators
• Maintenance and service providers
• Health and safety regulatory bodies

Implementation Implications

By rigorously implementing SIST EN 1953:2025, organizations can:

• Reduce workplace accidents and health risks
• Achieve CE marking and meet European Machinery and ATEX Directives
• Standardize maintenance and inspection procedures
• Drive employee trust and operational reliability

Manufacturers are required to conduct risk assessments, ensure robust mechanical and electrical design, provide detailed user documentation, and verify safety through prescribed testing.

Key highlights:

• Addresses all significant mechanical, electrical, and chemical hazards
• Includes explicit guidance for risk reduction, temperature and noise controls
• Ensures equipment meets stringent European health, safety, and explosion protection regulations

SIST EN ISO 19403-3:2025 - Surface Tension Measurement for Paints and Varnishes

Paints and Varnishes – Wettability – Part 3: Determination of the Surface Tension of Liquids Using the Pendant Drop Method (ISO 19403-3:2024)

SIST EN ISO 19403-3:2025 specifies a cutting-edge optical method for measuring the surface tension of liquid coatings via the pendant drop technique. This critical analytical approach allows chemists, quality controllers, and laboratory personnel to assess the behavior and application properties of paints, varnishes, and related coating materials.

Standard Scope and What It Covers

The pendant drop method described in this standard allows for:

• Precise characterization of the surface tension in liquid coatings
• Use of advanced imaging to analyze a droplet’s profile and compute surface tension
• Applicability to Newtonian liquids (with limitations for non-Newtonian substances)
• Reference to complementary methods for surface tension (EN 14370, ISO 1409)

Procedures include sample preparation, device calibration, environmental controls, data evaluation, and reporting requirements to ensure repeatability and reproducibility of results. This reliability is vital for product formulations where wettability influences application quality, adhesion, and final surface properties.

Who Should Comply?

• Paint and varnish manufacturers (formulation and R&D labs)
• Quality assurance and analytical testing labs
• Researchers in surface science and materials engineering

Implementation Implications

Adhering to SIST EN ISO 19403-3:2025 helps organizations:

• Achieve consistent and reproducible measurements across sites
• Validate product performance during development or batch release
• Troubleshoot coating or application failures linked to poor wettability
• Provide standardized data for regulatory filings and customer assurance

Strict adherence ensures that laboratory results are credible and comparable internationally, driving product acceptability and innovation.

Key highlights:

• Defines robust, standardized testing protocol (including repeatability and reproducibility limits)
• Mandates comprehensive documentation and reporting for transparency
• Enhances product quality by ensuring reliable wettability data
