ISO 3037 is an ISO test method for measuring the edgewise crush resistance of corrugated fibreboard using a non-waxed edge approach. It is widely used in packaging quality control to evaluate how well corrugated board can resist crushing when loaded along the flute direction.

ISO 3037: Corrugated fibreboard — Determination of edgewise crush resistance (non-waxed edge method)
ISO 3037 describes a standardized laboratory approach for determining edgewise crush resistance of corrugated fibreboard. In practical terms, this result is often used as a key performance indicator for corrugated packaging materials and as an input to box performance and quality specifications.
The method applies compressive force in the direction of the flute axis and is commonly performed on board samples taken from sheet stock, corrugated cases, or other converted corrugated products (when representative sampling is needed).
Quick Definition
What ISO 3037 measures: The edgewise crush resistance of corrugated fibreboard using a non-waxed edge method, with force applied along the flute axis.
How it is used: As a quality and specification test for corrugated board performance where consistent specimen preparation, alignment, and conditioning are critical to repeatable results.
What This Standard Covers
ISO 3037 focuses on edgewise compression of a rectangular corrugated fibreboard test piece placed between compression platens. The intent is to determine the maximum edgewise crush resistance reached under increasing compressive load, with the specimen oriented so the flute structure is loaded correctly.
The current ISO edition identifies applicability across common corrugated constructions (including single-wall, double-wall, and triple-wall) and a range of flute types, provided the measurement can be completed without invalid failure modes such as buckling or tipping.
Why This Standard Matters in Testing
Edgewise crush resistance is frequently used as a fast, production-friendly indicator for corrugated board strength and lot-to-lot consistency. Because this result is sensitive to cut quality, specimen alignment, and conditioning, standards-based testing helps reduce variability between shifts, sites, and suppliers.
For many packaging workflows, ISO 3037 results support incoming inspection of corrugated materials, verification of supplier certificates, process monitoring during board production or converting, and troubleshooting when box performance issues appear in distribution.
Common Materials, Product Types, or Applications Covered
ISO 3037 is used primarily for corrugated fibreboard packaging materials where edgewise compression strength is a key performance requirement.
Common applications: Corrugated shipping cases, retail-ready packaging, die-cut corrugated components, and corrugated board used for protective packaging structures.
Common material builds: Single-wall (double-faced), double-wall, and triple-wall corrugated fibreboard structures.
Common Test or Verification Workflow
A typical ISO 3037 workflow includes sampling, conditioning, preparation of rectangular test pieces, and edgewise compression between platens with controlled loading until failure criteria are reached and the maximum resistance is recorded.
Common workflow controls that affect results: Conditioning atmosphere, flute orientation, specimen cut quality (squareness and edge quality), platen alignment/parallelism, and minimizing off-axis loading that can cause tipping or premature buckling.
Equipment Commonly Used for This Standard
ISO 3037 is typically performed on a compression-testing system capable of applying a steadily increasing compressive force while keeping the specimen properly aligned between flat, parallel platens.
Common equipment: Compression tester or universal testing machine configured for compression, compression platens, specimen positioning aids or guides, and a cutting device designed to produce clean, square edges in corrugated board.
Practical selection notes: Because edge crush testing is sensitive to alignment, pay close attention to platen parallelism, stiffness of the load frame, and fixture setup that helps keep the specimen vertical and centered during loading.
If you are comparing load-frame capacity, platen size, alignment options, and specimen cutting solutions for corrugated board testing, you can request a detailed quote for a system configured around your throughput and reporting needs.
How to Read This Designation or Revision
ISO standards are commonly cited using the designation and publication year in the format “ISO 3037:YYYY”. The year identifies the edition that was used, which matters when your customer specification or internal procedure requires a particular version.
Revision sensitivity: Apparatus requirements, conditioning references, specimen preparation guidance, and reporting expectations can change between editions. When exchanging results with customers or suppliers, align on the exact cited edition before finalizing test settings and acceptance criteria.
Related Standards, Methods, or Frameworks when useful
ISO 3037 is commonly used alongside other paper/board standards that address sampling, conditioning, and compression equipment practices. Many lab procedures also reference internal or customer-specific packaging test plans that define sampling frequency, acceptance limits, and reporting format.
Common companion topics: Sampling plans for paper/board materials, standard conditioning atmospheres for paper-based products, and compression tester calibration/verification practices appropriate for corrugated board testing.
