Overview
ISO/TS 12927:1999 - "Lubricants, industrial oils and related products (class L) - Family M (Metalworking) - Guidelines for establishing specifications" is a Technical Specification that helps users define and agree product specifications for metalworking fluids and related lubricants. It is intended to facilitate application of the ISO 6743-7 classification and to provide a structured set of identification and performance characteristics that can form the basis of negotiations between end users and suppliers. The document is advisory (guidance only) and does not replace regulatory requirements for health, safety, disposal or the environment.
Key topics and requirements
- Purpose and scope
- Guidance to apply ISO 6743-7 classification and to state characteristics relevant for specifying metalworking fluids.
- Not a prescriptive specification - characteristics are non-exhaustive and intended for agreement between parties.
- Product families
- Covers both straight (non-aqueous) fluids and water-miscible concentrates for metalworking applications.
- Identification characteristics (examples)
- Viscosity, density, flash point, pour point, colour, appearance, refractive index, base/neutralization numbers.
- Performance characteristics (examples)
- Extreme pressure (EP) behaviour, anti-wear, friction reduction, anti-rust/corrosion protection, anti-mist, foaming, emulsion stability, gumming (sticking/residue), biological stability, filterability and compatibility with metals, paints and seals.
- Annexed test guidance
- Informative annexes include suggested methods for: anti-corrosive properties on non‑ferrous metals, evaluation of gumming tendency, and evaluation of biological stability for water‑miscible machining fluids.
- Use of normative references
Practical applications - who uses it
- Procurement teams and OEMs: to define machine shop and component vendor requirements for metalworking fluids.
- Lubricant manufacturers and suppliers: to prepare product data sheets and to propose test suites for qualification.
- Quality, R&D and laboratory personnel: to select relevant identification and performance tests and to document results for client evaluation.
- Standards committees and consultants: to harmonize specifications and translate classification codes (ISO-L-M…).
- Useful for machining shops, metal fabrication, automotive and aerospace suppliers, and industrial maintenance organizations that need clear, negotiated fluid specifications.
