Overview
ISO 15750-2:2002 defines requirements for steel drums - non‑removable head (tight head) with minimum total capacities of 212 l, 216.5 l and 230 l. The standard specifies key characteristics and dimensions for interchangeability in international trade, methods for measuring total capacity and brimful capacity, and a draining test to quantify residual liquid. It is intended for manufacturers, packagers, testing laboratories and purchasers of large steel tight‑head drums.
Key topics
- Scope and capacities: Applies to tight‑head steel drums with nominal total capacities of 212, 216.5 and 230 litres.
- Materials and thickness: Body and ends from commercial quality steel (ISO 3573/ISO 3574); steel thickness between 0.6 mm and 1.6 mm (normal tolerances).
- Construction details:
- Longitudinal body seam shall be welded.
- Heads permanently fixed to body by round seaming (six or more layers) or equivalent joining.
- Two rolling hoops (beads) located on the body; corrugations or alternative hoop constructions allowed.
- Closures positioned on the top end and shall not protrude above the chime.
- Closures and sealing:
- Closure thread sizes referenced to ISO 228-1 (threads G 3/4 and G 2).
- Gaskets/washers or other sealing elements required unless fittings are inherently leakproof.
- Closure materials: metal plugs and caps; plugs may be metal or plastic with appropriate gaskets.
- Capacity measurement:
- Gravimetric method (weighing water) in Annex A with temperature correction table and required weighing accuracy.
- Distinguishes total capacity (vented to remove trapped air) and brimful capacity (filled to overflow at normal filling position).
- Draining test:
- Annex B defines Procedure A (drum top half) and Procedure B (complete drum) to measure residue after drainage.
- Residual volume limit: not more than 100 ml for Procedure A (or as agreed for Procedure B).
- Designation: Example format - Tight head steel drum ISO 15750-2-216,5TC-A.
Applications and users
- Drum manufacturers - design and produce standardized tight‑head drums for global markets.
- Packagers and fillers - ensure compatibility with filling, handling and closure systems.
- Transport and logistics operators - verify drums meet dimensional stacking and transport requirements.
- Regulatory and compliance teams - align drum selection with dangerous goods transport rules (UN Model Regulations, ICAO, IMO/IMDG) and certification needs.
- Testing laboratories - perform capacity and drainability tests per the normative annexes.
