Quality and documentation
What to ask for before you buy DEF or lubricants, what each document tells you, and how we handle it.
The documents, explained
| Document | What it tells you | When to ask |
|---|---|---|
| Safety data sheet (SDS) | Hazards, handling, storage, spill response and first aid, in a standard 16-section format | For every product kept on site. Employers must keep SDSs available for hazardous chemicals under OSHA's Hazard Communication Standard. |
| Product or technical data sheet | Viscosity, API service category, OEM approvals, NLGI grade and typical properties | When matching a spec in your equipment manual |
| Certificate of analysis (COA) | Test results for a specific batch, such as DEF urea concentration | For bulk DEF loads or when a batch is in question |
| API DEF license | That the DEF brand is licensed by API and audited against ISO 22241 | Before choosing a DEF brand |
ISO 22241 for DEF
ISO 22241 sets the quality of DEF (32.5% high-purity urea in deionized water), how to test it, and how to handle and store it. Part 3 covers storage temperature, compatible materials and shelf life (ISO 22241-3:2017, Diesel engines NOx reduction agent AUS 32, Part 3: handling, transportation and storage). See does DEF go bad.
API DEF licensing
The API license belongs to the brand marketer, not to every company that resells it. That is why we never call ourselves API certified, and why we name the brand on every quote so you can look it up (American Petroleum Institute, Diesel Exhaust Fluid Certification Program). More in API certified DEF explained.
Lubricant specs
For oils and grease, the spec in your equipment manual decides the product: viscosity grade, API service category (for example CK-4 for heavy-duty diesel), OEM approvals, ISO grade for hydraulic oil, GL rating for gear oil and NLGI grade and thickener for grease. Send the spec and we quote products that meet it.
