Simply put: In Taiwan, the only official proof of compliance for industrial air treatment systems in combustible dust environments is the TS Safety Mark explosion-proof equipment certification. Under Occupational Safety and Health Administration (OSHA) regulations from the Ministry of Labor, electrical machinery used in hazardous areas must pass formal type inspection and display the TS Mark.
Many facility managers ask: “My machinery is already CE or ATEX certified—isn’t that enough?” The short answer is no. International credentials must be formally validated for local use. To protect your operations, here is a detailed breakdown of Taiwan’s explosion-proof regulations for TS Safety Mark explosion-proof equipment.
1. Legal Framework for Explosion-Proof Equipment in Taiwan
- Occupational Safety and Health Facilities Rules (Article 177-1): Employers operating in areas with combustible dust hazards must install certified explosion-proof equipment tailored to specific hazard zones.
- Occupational Safety and Health Act (Article 6): Employers are strictly prohibited from providing machinery or tools that fail to meet central authority safety standards.
- Mechanical Equipment Registration Regulations (Article 4): Machinery must pass type inspection by accredited testing bodies, complete official registration, and display the TS Mark.
2. What Is the TS Mark and How Is It Obtained?
- TS Mark Definition: Standing for “Taiwan Safety,” this certification proves a product has passed official type inspection by the Ministry of Labor’s OSHA.
- Governing Body: Occupational Safety and Health Administration, Ministry of Labor, Taiwan.
- Accredited Testing Bodies: Authorized institutions (such as the Industrial Safety Technology Center) conduct official type evaluations for TS Safety Mark explosion-proof equipment.
5-Step Acquisition Process:
- Submit an application for type inspection to an accredited testing body.
- Pass technical evaluations and secure certification paperwork.
- Register on the official Mechanical Equipment Registration Platform.
- Obtain the official registration certificate from the Ministry of Labor.
- Affix the TS Safety Mark label onto the machinery housing.
3. Can International Certifications (ATEX/IECEx) Be Used in Taiwan?
| Certification Type | Direct Validity in Taiwan | Application Status & Strategy |
| ATEX Certification (EU Directive) | Cannot be used directly | Requires full local type inspection to earn the TS Mark. |
| IECEx Certification (International) | Partially accepted | Test reports serve as accepted evidence, significantly speeding up the local TS Mark registration process. |
| TS Safety Mark (Taiwan) | Fully legal & mandatory | The only legal mark required for compliance in Taiwan. |
4. National Standard Cross-Reference (CNS vs. IEC)
- General Requirements: CNS 3376-0 correlates directly to IEC 60079-0.
- Flameproof Enclosure “d”: CNS 3376-1 correlates directly to IEC 60079-1.
- Pressurized Enclosure “p”: CNS 3376-2 correlates directly to IEC 60079-2.
- Intrinsic Safety “i”: CNS 3376-11 correlates directly to IEC 60079-11.
- Encapsulation “m”: CNS 3376-18 correlates directly to IEC 60079-18.
5. Risks of Using Uncertified Dust Collectors
Avoid these severe consequences by ensuring your dust collection systems are fully certified:
- Labor Inspection Penalties: OSHA audits issue immediate citations and fines for non-TS marked equipment in hazardous zones.
- Insurance Claim Denials: Insurers can refuse coverage payouts following an explosion incident due to unlawful equipment use.
- Criminal Liability: Facility management faces potential criminal charges for negligence in worker injury events.
- Customs Impoundment: Imported machinery lacking proper TS Mark registration risks being held at customs.
