Understanding TISI Certified Power Cords: Requirements, Structure, and Market Demand in Thailand

1. What Is TISI Certification?

TISI stands for Thai Industrial Standards Institute, responsible for regulating safety standards in Thailand. TISI certification ensures that electrical products, including power plugs, connectors, and power cords, meet Thailand’s safety and performance requirements.

TISI certification is compulsory for many electrical products, especially:

• Power plugs

• Power cords

• Household appliances

• Lighting equipment

• Power adapters

Without TISI approval, the product cannot be legally imported or sold in Thailand.

2. Thailand’s Standard for Power Cords: TIS 166-2549

The main standard for power plugs and cords in Thailand is TIS 166-2549, which aligns closely with IEC standards but includes Thailand-specific requirements.

Key technical requirements include:

2.1 Plug Pin Structure

• Type O plug is the official Thai plug standard

• Pins must be solid, corrosion-resistant, and precisely aligned

• TISI requires enhanced durability testing for frequent plugging/unplugging

2.2 Cable Construction

TISI power cords typically follow IEC cable types such as:

• H05VV-F

• H03VV-F

• H05RN-F

Requirements include:

• Accurate conductor size

• High-quality PVC or rubber insulation

• Flame retardant materials

• Adequate tensile strength

2.3 Safety Tests

Products must pass:

• Aging tests

• Electrical strength tests

• Plug heating tests

• Bending and flexing tests

• Insulation resistance tests

TISI-certified cords must be durable enough for Thailand’s hot and humid climate.
