Full title and description

VDI 3397 Blatt 2:2014-06 — Maintenance of metalworking fluids for metalcutting and forming operations — Measures for maintaining quality, process improvement, and for reducing solid and liquid waste. The document gives practical recommendations for the care, monitoring, cleaning and eventual disposal of metalworking fluids (coolants and cutting fluids) used in machining and forming processes.

Abstract

This part of VDI 3397 describes system concepts for metalworking-fluid circulation, monitoring methods, mechanical/physical and chemical measures to preserve fluid quality, temperature control, procedures for refill or new-fill operations, disposal and fire-protection measures. It is intended to extend fluid lifetime, reduce production costs and lower solid and liquid waste generation. It is to be used in conjunction with VDI 3397 Blatt 1 and Blatt 3 and with VDI 3035.

Scope

VDI 3397 Blatt 2 covers measures for the maintenance and monitoring of metalworking fluids used in machining and forming processes, including system concepts for recirculation, separation and filtration technologies, chemical and physical treatment options, temperature control, criteria for new-fill and change-out, and guidance on disposal and reducing wastewater and solid waste. It is intended to be applied together with the other parts of VDI 3397 and related machine- and lubricant-design standards.

Key topics and requirements

• System concepts for metalworking-fluid circulation and peripheral equipment (skimmers, separators, filters, flotation and centrifuges).
• Methods and intervals for monitoring fluid condition (concentration, pH, microbial contamination, tramp oils, nitrite, etc.).
• Mechanical/physical separation techniques for solid and liquid contaminants and guidance on selecting appropriate cleaning equipment.
• Temperature control and its influence on fluid performance and microbiological growth.
• Chemical and physical treatment measures to extend fluid life (biocide strategies, replenishment, compatibility checks).
• Criteria and procedures for metalworking-fluid change (new fill) and responsible disposal practices to minimize waste and wastewater.
• Recommendations for process-improvement measures to reduce consumption and increase occupational and environmental safety.

These topics are presented with practical tables and selection aids for cleaning/filtration equipment and monitoring approaches.

Typical use and users

Used by production and process engineers, maintenance teams, environmental/safety officers, lubricant and fluid-management service providers, machine builders and quality managers to set up, operate and audit coolant and cutting-fluid systems for machining and forming operations. Also used as a technical reference for supplier recommendations and for training of personnel responsible for coolant care.

Related standards

Intended to be used together with other parts of VDI 3397 (Blatt 1 and Blatt 3) and VDI 3035. It is commonly referenced alongside national regulations and guidance such as TRGS 611 (use restrictions for certain metalworking fluids) and DGUV/DGUV-IFA guidance on coolant handling and workplace air.

FAQ

Q: What is this standard?

A: VDI 3397 Blatt 2:2014-06 is a VDI technical rule that provides practical measures and recommendations for maintaining metalworking fluids used in machining and forming processes, with the goal of preserving fluid quality and reducing waste.

Q: What does it cover?

A: It covers system concepts for fluid circulation, monitoring parameters and methods, mechanical and chemical cleaning/treatment options, temperature control, procedures for changing or refilling fluids, disposal guidance and fire-protection considerations.

Q: Who typically uses it?

A: Production/process engineers, maintenance and reliability staff, environmental and safety officers, fluid suppliers and service providers, and machine-tool manufacturers—anyone responsible for specifying, operating or auditing coolant and cutting-fluid systems.

Q: Is it current or superseded?

A: The 2014-06 edition is the current edition of VDI 3397 Blatt 2 and replaced the 2005-09 version; earlier unrelated drafts/parts from the 1990s were withdrawn. Users should check national adoption notices or the VDI catalogue for any later amendments.

Q: Is it part of a series?

A: Yes — VDI 3397 is a multi-part guideline. Blatt 2 is one part addressing maintenance and waste reduction; it is intended to be used together with Blatt 1 and Blatt 3 (and cross-referenced with VDI 3035).
