Overview
EN ISO 15750-2:2008 (ISO 15750-2:2002) is a CEN-endorsed international standard that specifies the characteristics, dimensions and test methods for non-removable head (tight head) steel drums with minimum total capacities of 212 l, 216.5 l and 230 l. It covers construction, materials, closures, capacity measurement and drainage requirements to ensure interchangeability and practical use in packaging and transport of liquids.
Key topics and technical requirements
- Drum types & dimensions: Defines three drum types (A, B, C) with exact dimensional limits (e.g., internal diameter ~571.5 mm for several types, specified total heights and bead positions) to support compatibility and stacking.
- Material & thickness: Body and ends made from steel sheet (cold‑reduced CR1 or hot‑rolled HR1 per ISO 3574/ISO 3573); thickness between 0.6 mm and 1.6 mm with normal tolerances.
- Construction:
- Longitudinal body seam welded.
- Bodies and ends permanently fixed by round seaming (or other agreed joining methods).
- Two rolling hoops (beads) recommended; optional corrugations/reinforcements allowed.
- Closures located in the top, diametrically opposed.
- Closures & threads: Closure pitch diameters and threads follow ISO 228-1 (threads G 3/4 and G 2). Closure systems are expected to conform to ISO 15750-3 unless otherwise agreed.
- Capacity measurement (Annex A):
- Gravimetric method: measure mass of water, convert to volume; weighing accuracy at least 0.1%.
- Temperature-dependent correction factors for water density are provided.
- Procedure includes venting hole, filling through designed orifice and weighing empty vs filled drum.
- Draining (Annex B): Design should minimize residual liquid - residue must be ≤ 100 ml when tested by procedure A (or as mutually agreed for procedure B).
- Finish & compatibility: Internal/external finishes and protective coatings to be agreed to ensure chemical compatibility with contents.
Applications and users
This standard is primarily used by:
- Steel drum manufacturers and tooling designers for compliant production.
- Packaging engineers and purchasers specifying drums for storage, handling and transport.
- Testing laboratories performing capacity and drainage verification.
- Logistics, chemical and oil companies that require standardized packaging for liquids (including those subject to dangerous‑goods transport regulations).
Practical benefits include improved interchangeability, predictable filling/emptying behavior and easier compliance with transport/stacking requirements.
