ISO 22241-3-2017 PDF

Full title and description

St ISO 22241-3-2017 — "Diesel engines — NOx reduction agent AUS 32 — Part 3: Handling, transportation and storage". This part of ISO 22241 provides recommendations and mandatory requirements to preserve AUS 32 (aqueous urea solution, commonly called AdBlue/DEF) quality through handling, transport and storage in the supply chain so that selective catalytic reduction (SCR) systems function correctly.

Abstract

Part 3 of ISO 22241 sets out practical requirements and best-practice guidance for materials compatibility, contamination control, packaging, sampling/retained samples, temperature limits and shelf‑life considerations for AUS 32 from production to vehicle fill. Its purpose is to avoid contamination and decomposition that would impair SCR performance.

• ICS / categories: 43.060.40 (Fuel systems / road-vehicle fuel systems).
• Edition / version: 2017 edition (ISO 22241-3:2017). Replaces earlier 2008 edition.
• Number of pages: Official ISO distribution lists a short technical document (commonly ~9 pages in some ISO publisher listings); some national-adoption publications (e.g., BSI) show longer formatted documents (e.g., 18 pages) depending on national forewords/formatting.

Scope

ISO 22241-3:2017 applies to the handling, transportation and storage of AUS 32 across the supply chain from production until filling into vehicle on‑board tanks or other applications. It gives material selection guidance for surfaces in contact with AUS 32, procedures to avoid contamination, storage and transport temperature recommendations, packaging and sampling/retained-sample practices, batch traceability and quality‑assurance requirements to ensure compatibility with ISO 22241-1 quality limits.

Key topics and requirements

• Materials compatibility: recommended materials for wetted surfaces (for example selected stainless steels, certain plastics and fluoropolymers); materials to avoid (carbon steels, copper and many copper alloys, aluminium, lead‑containing solders) and requirement to test uncertain materials under realistic conditions.
• Temperature and physical storage guidance: avoid prolonged exposure above ~30 °C (risk of decomposition) and below freezing (≈ −5 °C and below) where solids can form and containers can be damaged; protect from sunlight and temperature cycling.
• Shelf life guidance: recommended maximum shelf lives that depend on storage temperature (examples given in guidance: long shelf life at low constant temperatures, progressively shorter at higher ambient temperatures — the standard gives concrete temperature-to-shelf-life guidance and recommends testing material stored outside recommended conditions).
• Contamination control and cleanliness: procedures to keep surfaces, lines and containers free from fuels, oils, detergents and trace-metal contamination; final cleaning with de‑ionized water and an AUS 32 rinse is recommended; strict sampling and retained-sample rules.
• Quality assurance and traceability: batch identification, certificates of analysis, sampling and testing (in accordance with ISO 22241-2 test methods and ISO 22241-1 quality limits), procedures for handling non‑conforming material and retained-sample storage.
• Packaging and handling: guidance for single‑use containers, intermediate bulk containers (IBCs), dedicated vs non‑dedicated bulk systems, marking and labelling and safe transport practices to avoid contamination or physical damage.

Typical use and users

Users include AUS 32 (DEF/AdBlue) manufacturers and packagers, logistic and bulk‑transport operators, warehouse/storage operators, vehicle and engine OEMs, fuel and fleet operators, testing laboratories and quality managers. The document is used to design and audit handling/storage processes, prepare supplier contracts and certificates of analysis, and to establish incident/dispense procedures to protect SCR system performance.

Related standards

ISO 22241 is a multipart series. Closely related documents are ISO 22241-1 (Quality requirements for AUS 32) and ISO 22241-2 (Test methods for determining AUS 32 characteristics); ISO 22241-4 covers refilling interfaces and has later editions (2019, updated 2023). Users typically apply ISO 22241-1 together with Part 2 and Part 3 to ensure product quality, testing and correct handling/storage.

FAQ

Q: What is this standard?

A: ISO 22241-3:2017 is the part of the ISO 22241 series that specifies handling, transportation and storage requirements for AUS 32 (aqueous urea solution used for NOx reduction in SCR systems).

Q: What does it cover?

A: It covers materials compatibility for wetted surfaces, packaging and labelling, contamination control, temperature and shelf‑life guidance, sampling and retained-sample practices, quality assurance and traceability across supply-chain operations.

Q: Who typically uses it?

A: AUS 32 producers, packagers and distributors; vehicle and engine manufacturers and dealerships; fleet operators; storage and transport providers; testing laboratories and quality managers.

Q: Is it current or superseded?

A: ISO 22241-3:2017 is the 2017 edition that replaced earlier editions (for example a 2008 edition). National adoptions such as BS ISO 22241-3:2017 reflect the 2017 edition. Users should check their national standards body or ISO catalogue for any further reviews or amendments.

Q: Is it part of a series?

A: Yes — ISO 22241 is a multipart standard covering AUS 32: Part 1 (quality requirements), Part 2 (test methods), Part 3 (handling/transport/storage) and Part 4 (refilling interface); consult the series for full product specification, test and application interface details.
