Full title and description

STB VDI 3456 2009-12 — Emissionsminderung - Reparaturlackierung und Lackierung von Fahrzeugen (English title: Emission control - Refinishing and finishing of vehicles). This document is the VDI guidance/technical rule edition published December 2009 addressing measures to reduce emissions (especially VOCs and solvent emissions) and to protect health and the environment when refinishing and painting vehicles.

Abstract

This standard provides practical and technical guidance for minimizing air emissions and other environmental impacts from vehicle refinishing and finishing processes. It covers process technology, ventilation and spray booth design, solvent management, cleaning systems, emission calculation and reporting, occupational safety (including handling of isocyanate-containing materials), energy-saving measures and recommended control options for small and medium-sized enterprises as well as larger vehicle-construction or conversion operations. It is intended to be used where vehicle painting and repair-lacquering are performed and to support compliance with applicable environmental and workplace-safety requirements.

Scope

The scope covers paint and refinishing applications on passenger cars and commercial vehicles carried out by manual or semi-manual processes, including repair spot painting, complete vehicle refinishing, and coating work involved in vehicle conversion or body-building. The standard describes state-of-the-art technical and organizational measures to avoid or reduce emissions (solvents, VOCs, particulates), gives guidance on emission calculation and documentation, and includes aspects of occupational safety, waste and wastewater handling, and energy efficiency. It is applicable to stationary and mobile refinishing installations that are not necessarily subject to specific permitting, but its recommendations may also be used for permitting and for authorisation-bound facilities.

Key topics and requirements

• Overview of refinishing workflows and emission sources (pre-treatment, spraying, drying, cleaning).
• Measures to reduce VOC emissions: product selection, low-VOC coatings, process optimisation.
• Ventilation, spray booth and exhaust design criteria to control emissions and worker exposure.
• Closed/controlled cleaning systems for application tools and solvent recovery recommendations.
• Guidance on calculating emissions and VOC balances, and on preparing solvent management plans.
• Occupational health and safety provisions, including protective equipment and special considerations for isocyanate-containing materials.
• Energy efficiency and measures to reduce process energy consumption (IR/UV drying, heat recovery).
• Waste, wastewater and other environmental aspects (disposal, minimisation strategies).
• Recommended documentation and verification schemes for demonstrating compliance.

Typical use and users

Primary users are vehicle body repair shops, automotive refinishing businesses, fleet maintenance facilities, commercial vehicle converters and manufacturers carrying out manual coating work. Secondary users include environmental and health & safety engineers, regulatory authorities, consultants, paint and equipment suppliers, and designers of spray booths and solvent-recovery systems.

Related standards

FAQ

Q: What is this standard?

A: VDI 3456:2009-12 is a VDI guideline/technical rule titled "Emissionsminderung - Reparaturlackierung und Lackierung von Fahrzeugen" (Emission control - Refinishing and finishing of vehicles). It sets out recommended technical and organisational measures to reduce emissions and protect health during vehicle refinishing and painting operations.

Q: What does it cover?

A: It covers the full refinishing process chain (preparation, spraying, drying, cleaning), emission reduction measures (product choice, process controls, booth design), emission calculation and solvent-management planning, waste handling, energy-saving options, and occupational safety measures including guidance for handling isocyanate-containing materials.

Q: Who typically uses it?

A: Vehicle body and paint shops (small, medium and larger operations), vehicle converters, environmental and safety engineers, paint and equipment suppliers, and regulatory bodies use the guidance to design compliant processes, select equipment and document emission-control measures.

Q: Is it current or superseded?

A: The 2009-12 edition is superseded. The content of VDI 3456:2009-12 was replaced by a later edition published on 1 May 2018 (VDI 3456:2018-05). Users should consult the 2018 edition for the most up-to-date recommendations; however, the 2009 text remains useful for historical reference and for facilities operating under older approvals.

Q: Is it part of a series?

A: Yes. VDI 3456 is part of a family of VDI guidance and technical rules addressing emission control and painting processes for vehicles and industrial coating (for example VDI 3455, VDI 3457 and VDI 4075 series), and it is commonly used alongside national regulatory documents and industry best-practice guidance.

Q: What are the key keywords?

A: Emission control, refinishing, vehicle painting, VOC, solvent management, spray booth, ventilation, isocyanates, occupational safety, energy efficiency.
