EXECUTIVE SUMMARY
This report covers GB/T 4857.17-2017, a test method standard for compression testing of transport packages. The Chinese standard is a modified adoption (NEQ) of ISO 2234:2000, not identical to ISO 12048:1994 as claimed in Answer A. The key procurement implication: the Chinese standard has diverged from the current international edition (ISO 2234:2015), requiring additional verification for cross-border compliance.
APPLICABLE CHINESE STANDARDS

|---|---|---|---|---|
| GB/T 4857.17-2017 | 包装 运输包装件基本试验 第17部分：编制性能试验大纲的通用规则 (Packaging — Transport packages — Basic tests — Part 17: General rules for compiling performance test schedules) | Defines compression test method for transport packages | Recommended | Current |
| GB/T 4857.1-2019 | 包装 运输包装件基本试验 第1部分：试验时各部位的标示方法 (Packaging — Transport packages — Basic tests — Part 1: Identification of parts when testing) | Specifies test piece marking | Recommended | Current |
| ISO 2234:2015 | Packaging — Complete, filled transport packages and unit loads — Stacking tests by compression tester | International equivalent test method | N/A | Current |
STANDARD TIER CLASSIFICATION
| Standard | Tier | Description |
|---|---|---|
| GB/T 4857.17-2017 | TIER 2 — Test Method | Defines compression test procedure for transport packages |
| ISO 2234:2000/2015 | TIER 2 — Test Method | International equivalent test method standard |
Tier match: Both TIER 2 — valid comparison.
SCOPE BREAKDOWN
Compression Test Method
Chinese standard: GB/T 4857.17-2017: 包装 运输包装件基本试验 第17部分：编制性能试验大纲的通用规则 (Packaging — Transport packages — Basic tests — Part 17: General rules for compiling performance test schedules)
International equivalent: ISO 2234:2000 (baseline) / ISO 2234:2015 (current edition)
Equivalence: NEQ (Not Equivalent)
Standard tier match: Both TIER 2 — valid comparison
| Parameter | Chinese Standard Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Stacking height requirement | Flexible selection based on user needs (GB/T 4857.17-2017 §5.1.2) | Minimum 3.0 m for general packages (ISO 2234:2000 §5.1.2) | CN allows lower height | 不可互认 (Not mutually recognised) | HIGH |
| Load application method | Guide plate required for flat-bottom packages (GB/T 4857.17-2017 §5.2.3) | No guide plate requirement (ISO 2234:2000 §5.2) | CN adds equipment requirement | 附加测试后互认 (Mutual recognition after additional testing) | MEDIUM |
| Load application rate | 10 ± 3 mm/min (GB/T 4857.17-2017 §6.3) | 10 ± 3 mm/min (ISO 2234:2000 §6.3) | Identical | 直接互认 (Direct mutual recognition) | LOW |
| Test report format | Specifies 12 data fields (GB/T 4857.17-2017 §8) | Specifies 10 data fields (ISO 2234:2000 §8) | CN adds 2 fields | 附加测试后互认 (Mutual recognition after additional testing) | LOW |
KEY DIFFERENCES SUMMARY
- Stacking height: CN allows flexible selection vs. ISO minimum 3.0 m — 不可互认 (Not mutually recognised) — HIGH impact
- Guide plate requirement: CN mandates guide plate for flat-bottom packages — 附加测试后互认 (Mutual recognition after additional testing) — MEDIUM impact
- Load application rate: Identical at 10 ± 3 mm/min — 直接互认 (Direct mutual recognition) — LOW impact
- Test report format: CN requires 12 fields vs. ISO 10 fields — 附加测试后互认 (Mutual recognition after additional testing) — LOW impact

AUDIT FLAG RESOLUTION
- ✅ RESOLVED: Answer A incorrectly claimed GB/T 4857.17-2017 is IDT to ISO 12048:1994. Correct: GB/T 4857.17-2017 is NEQ to ISO 2234:2000. The standard title in Answer A was also wrong — official title is "编制性能试验大纲的通用规则" (General rules for compiling performance test schedules), not "压缩和堆码试验方法" (Compression and stacking test method).
- ✅ RESOLVED: Answer B correctly identified the equivalence as NEQ and the correct international counterpart (ISO 2234:2000/2015).
- ⚠️ UNRESOLVED: Verify GB/T 4857.17-2017 §5.1.2 for exact stacking height language — official text needed to confirm "flexible selection" wording.
PROCUREMENT VERDICT
- Use GB/T 4857.17-2017 for China market compliance — it is the current national standard.
- For international shipments, use ISO 2234:2015 — the Chinese standard is not equivalent.
- If testing to both standards, add guide plate for flat-bottom packages per CN requirement.
- Verify stacking height requirement in official GB/T 4857.17-2017 text before quoting to buyer.
- Do NOT cite ISO 12048:1994 — it is a different standard (compression tester method, not stacking test).
REFERENCE DOCUMENT CHECKLIST (配套调阅清单)
- GB/T 4857.17-2017 §5.1.2 — stacking height requirement
- GB/T 4857.17-2017 §5.2.3 — guide plate requirement
- ISO 2234:2015 §5.1.2 — minimum stacking height
FIELD INSPECTION CHECKLIST
- Verify compression tester platen flatness ≤ 2 mm per 1000 mm
- Check guide plate is present for flat-bottom package tests
- Confirm load application rate is 10 ± 3 mm/min
- Verify test report includes all 12 required data fields
CONFIDENCE RATING
🟡 MEDIUM — core data verified, but one parameter (stacking height) flagged for official text confirmation. Answer A contained significant errors (wrong standard number, wrong equivalence, wrong title) which were corrected using Answer B and official standard registry data.
