Standards Comparison Report
BS EN ISO 12100:2010
EXECUTIVE SUMMARY
This report compares BS EN ISO 12100:2010 (Safety of machinery — General principles for design — Risk assessment and risk reduction) with its Chinese equivalent GB/T 15706-2012. Both are Type-A fundamental safety standards with identical technical content; the Chinese version is MOD (modified) due to structural reorganization and replacement of normative references. Procurement implication: no product-specific numeric limits exist in either standard — compliance verification requires reference to Type-B/C standards.
APPLICABLE CHINESE STANDARDS
| Standard No. | Title (Chinese) | Scope | Mandatory/Recommended | Status |
|---|---|---|---|---|
| GB/T 15706-2012 | 机械安全 设计通则 风险评估与风险减小 (Safety of machinery — General principles for design — Risk assessment and risk reduction) | General principles for machinery design risk assessment and reduction | Recommended | Current |
| GB/T 16855.1-2018 | 机械安全 控制系统安全相关部件 第1部分：设计通则 (Safety of machinery — Safety-related parts of control systems — Part 1: General principles for design) | Control system safety design (Type-B standard) | Recommended | Current |

STANDARD TIER CLASSIFICATION
| Standard | Tier | Description |
|---|---|---|
| GB/T 15706-2012 | TIER 2 — Design Principle Standard | Type-A fundamental safety standard — defines risk assessment methodology, not product-specific limits |
| BS EN ISO 12100:2010 | TIER 2 — Design Principle Standard | Identical Type-A classification — same methodology scope |
SCOPE BREAKDOWN
Risk Assessment Methodology
Chinese standard: GB/T 15706-2012: 机械安全 设计通则 风险评估与风险减小 (Safety of machinery — General principles for design — Risk assessment and risk reduction)
International equivalent: BS EN ISO 12100:2010: Safety of machinery — General principles for design — Risk assessment and risk reduction (2010 edition)
Equivalence: MOD (modified adoption)
Standard tier match: Both TIER 2 — valid comparison
| Parameter | Chinese Standard Value (Clause) | International Value (Clause) | Deviation | Mutual Recognition | Procurement Impact |
|---|---|---|---|---|---|
| Risk assessment process | Three-step iterative process: risk analysis → risk evaluation → risk reduction (GB/T 15706-2012 §5.2) | Three-step iterative process: risk analysis → risk evaluation → risk reduction (BS EN ISO 12100:2010 §5.2) | Identical methodology | 直接互认 (Direct mutual recognition) | LOW |
| Hazard identification categories | Mechanical, electrical, thermal, noise, vibration, radiation, material/substance, ergonomic, combination (GB/T 15706-2012 §6.1, Table 1) | Same categories (BS EN ISO 12100:2010 §6.1, Table 1) | Identical | 直接互认 (Direct mutual recognition) | LOW |
| Risk reduction hierarchy | Inherently safe design → safeguarding/complementary measures → information for use (GB/T 15706-2012 §6.2) | Same hierarchy (BS EN ISO 12100:2010 §6.2) | Identical | 直接互认 (Direct mutual recognition) | LOW |
| Normative references | GB/T 16855.1 (control systems), GB/T 8196 (guards) (GB/T 15706-2012 §2) | ISO 13849-1 (control systems), ISO 14120 (guards) (BS EN ISO 12100:2010 §2) | Chinese references replaced ISO equivalents | 附加测试后互认 (Mutual recognition after additional testing) | MEDIUM |
| Annex structure | Annex A (informative): Chinese-specific terms; Annex B: hazard examples; Annex C: bibliography (GB/T 15706-2012 Annex A-C) | Annex A: hazard examples; Annex B: bibliography (BS EN ISO 12100:2010 Annex A-B) | GB/T adds Chinese-specific terminology annex | 附加测试后互认 (Mutual recognition after additional testing) | LOW |
KEY DIFFERENCES SUMMARY
- Normative references: GB/T 15706-2012 replaces ISO 13849-1 with GB/T 16855.1, and ISO 14120 with GB/T 8196 — 附加测试后互认 (Mutual recognition after additional testing) — MEDIUM impact (verify equivalence of referenced Chinese standards)
- Annex structure: GB/T 15706-2012 adds Annex A with Chinese-specific terminology — 附加测试后互认 (Mutual recognition after additional testing) — LOW impact (informative only)
- Document structure: GB/T 15706-2012 merges ISO 12100 Parts 1 and 2 into single document with renumbered clauses — 直接互认 (Direct mutual recognition) — LOW impact (no technical change)
REGULATORY LINKAGE TABLE (法规联动)
| Compliance Scenario | Chinese Regulatory Basis | International Regulatory Basis |
|---|---|---|
| Mandatory product certification | CCC (China Compulsory Certification) for specific machinery types per CNCA catalog | CE marking (Machinery Directive 2006/42/EC) for EU market |
| Engineering acceptance inspection | GB 5083-1999 (Safety requirements for production equipment) | EN 60204-1 (Electrical equipment of machines) |
| Import/export compliance | CCIB (Commodity Inspection Bureau) for machinery imports | Destination country customs standard (e.g., UKCA for UK) |
| Designer/engineer obligation | GB/T 15706-2012 §5-6 (risk assessment methodology) | BS EN ISO 12100:2010 §5-6 (same methodology) |
AUDIT FLAG RESOLUTION
- ✅ RESOLVED: Both A and B correctly identify GB/T 15706-2012 as MOD to ISO 12100:2010. No numeric parameter disputes exist.
- ✅ FALSE POSITIVE (domain flag): GB/T 15706-2012 — flagged as potential misapplication for product-specific comparison, but usage is valid because it is the direct Chinese equivalent of BS EN ISO 12100:2010 (Type-A standard). No product-specific limits are expected.
PROCUREMENT VERDICT
- Confirm that machinery design follows risk assessment methodology per GB/T 15706-2012 §5-6
- Verify that referenced Type-B/C standards (e.g., GB/T 16855.1, GB/T 8196) are equivalent to their ISO counterparts
- Ensure CCC certification for machinery types listed in CNCA catalog
- For CE/UKCA markets, use BS EN ISO 12100:2010 directly — no additional testing required for methodology
