Overview
ISO 13127:2012 - Packaging - Child resistant packaging - Mechanical test methods for reclosable child resistant packaging systems - specifies reproducible mechanical test methods for evaluating reclosable child‑resistant packaging. The standard provides a scientific basis to compare child resistant characteristics of related reclosable packaging systems and to support change management decisions. It is intended to supplement, not replace, the human panel tests required by ISO 8317 for type approval.
Key topics and technical requirements
- Scope and purpose
- Defines mechanical testing methods for reclosable child‑resistant systems to produce data suitable for comparison with type‑approved packages.
- Not intended for routine quality assurance.
- Test methods and annexes
- Normative annexes specify mechanical tests, including (but not limited to): torque release, squeeze, non‑squeeze torque, press down and turn engagement, push and turn, reverse ratchet torque, disassembly, rotational torque, push‑off force, and application force.
- General requirements
- Guidance on testing facilities, sample selection and preparation, and assessment of results.
- Test method selection driven by packaging type and risk assessment.
- Reference data
- Reference data are to be generated from type‑approved packages and used to set acceptance parameters for related packaging.
- Change management
- Mechanical tests support evaluation of minor changes (supplier, material, component site, scale‑up) provided a documented risk assessment shows mechanical testing can reliably measure impacts.
- Changes affecting essential characteristics (critical dimensions, materials, thread form, sealing features, handling/grip features, rigidity, etc.) require thorough evaluation; major changes may still require ISO 8317 panel testing.
- Test reporting
- Clause 7 specifies required test report items: facility, applicant, manufacturer, packaging description, test description and results, references and signature.
Applications and practical value
- Use mechanical test data to:
- Verify equivalency to a type‑approved reclosable child‑resistant package during change management.
- Support risk assessments when altering materials, components, or suppliers.
- Provide objective, reproducible metrics for design validation and comparison of closure/container variants.
- Typical users:
- Packaging designers and manufacturers
- Component and liner suppliers
- Third‑party testing laboratories
- Regulatory and compliance teams assessing product safety changes
