GB 4706.1 Explained: China's Household Appliance Safety Standard
Anyone making appliances for the Chinese market runs into GB 4706.1. In one sentence: it is the general safety rulebook for household appliances — the specific product then adds a "Part 2" special requirement on top.
What it covers
Household and similar electrical appliances, essentially all of them:
Rice cookers, kettles, pressure cookers, hair dryers, space heaters, microwave ovens, washing machines, range hoods, induction cookers, dishwashers, tumble dryers, massage appliances...
Note the words "and similar" — it also pulls in comparable commercial and light-industrial equipment (there are GB 4706 special parts for commercial deep fryers and even electric fishing devices).
General part + special part, used as a pair
GB 4706.1 is Part 1, the general requirements — on its own it cannot certify a product. In practice you pair them:
| Product | General | Special |
|---|---|---|
| Rice cooker | GB 4706.1 | GB 4706.19 |
| Microwave oven | GB 4706.1 | GB 4706.21 |
| Range hood | GB 4706.1 | GB 4706.28 |
| Induction cooker | GB 4706.1 | GB 4706.29 |
Our knowledge base currently holds 52 standards in the GB 4706 series (general plus product-specific parts). Before testing, confirm which special part applies — a report covering only the general requirement is incomplete.
Identical to IEC 60335-1
The cover of GB 4706.1-2005 states the adoption relationship: GB 4706.1—2005 / IEC 60335-1:2004(Ed4.1) — identical adoption.
So the technical requirements match the international standard. For export:
- Europe → EN 60335-1 (harmonised standard under the Low Voltage Directive)
- US → UL 60335-1
- International certification → IEC 60335-1
Same design logic, different reports and marks.
Five appliance classes — where people most often slip
Clause 6 classifies appliances by protection against electric shock, which directly determines earthing and insulation design:
| Class | Protection method |
|---|---|
| Class 0 | Basic insulation only, no earthing provision |
| Class 0I | Basic insulation throughout, with an earth terminal, but the supply cord has no earth conductor and the plug has no earth pin |
| Class I | Basic insulation plus an additional safeguard — accessible conductive parts connected to the protective earthing conductor |
| Class II | Double or reinforced insulation, not relying on earthing |
| Class III | Supplied at safety extra-low voltage |
The standard's own wording for Class 0I is precise: "an appliance having at least basic insulation throughout and incorporating an earth terminal, but with a supply cord without an earth conductor and a plug without an earth pin".
Practical warning: Class I and Class II are the easiest to confuse. A plastic enclosure does not make something Class II — Class II requires double or reinforced insulation, and the judgement is about insulation structure, not housing material.
What the 32 clauses check (the ones that matter)
The main body has 32 clauses. For product work, focus on:
- Clause 7 Marking and instructions — rating plate, warnings, instruction manual (the most frequently cited non-conformity)
- Clause 8 Protection against access to live parts — can test fingers and pins reach live parts
- Clause 10 Power input and current — measured deviation within limits
- Clause 11 Heating — temperature rise limits for windings, enclosure, handles
- Clauses 13/16 Leakage current and electric strength — at operating temperature and after humidity treatment
- Clause 15 Moisture resistance — must still withstand electric strength after humidity
- Clause 19 Abnormal operation — locked rotor, short circuit, misuse
- Clause 25 Supply connection and external flexible cords — cord specification and connection
- Clause 27 Provision for earthing — earth continuity for Class I
- Clause 29 Clearances, creepage distances and solid insulation — distance measurement
- Clause 30 Resistance to heat and fire — ball pressure and glow-wire tests
Annex B matters: appliances with rechargeable batteries
Annex B is "Appliances supplied with battery power" — a normative annex. Many small appliances now contain lithium batteries (cordless vacuums, electric toothbrushes, portable fans, rechargeable shavers), so these requirements apply.
Transport adds UN 38.3 for lithium batteries, covered separately.
The CCC connection
Household appliances fall under China's compulsory product certification (CCC). For CCC, the safety testing is done against GB 4706.1 plus the applicable special part.
So GB 4706.1 is the technical foundation of Chinese CCC appliance certification. For export to Europe, you work to EN 60335-1 under the Low Voltage Directive instead.
Three practical tips
- Identify the special part first — confirm which GB 4706.x applies; the general part alone is not enough.
- Settle the appliance class early — Class I vs Class II drives insulation, earthing and cord design; changing later is expensive.
- Don't miss Annex B for battery appliances — commonly overlooked for small appliances with lithium cells.

FAQ
Which products does GB 4706.1 cover?
Household and similar electrical appliances: rice cookers, kettles, hair dryers, heaters, microwave ovens, washing machines, range hoods. It is the general requirement — certification pairs it with the product-specific part, e.g. GB 4706.19 for rice cookers, GB 4706.21 for microwave ovens.
How does GB 4706.1 relate to IEC 60335-1?
GB 4706.1-2005 is identical to IEC 60335-1:2004 (Ed 4.1) — the technical requirements match. For export: EN 60335-1 in Europe, UL 60335-1 in the US.
What are appliance class 0, I, II and III?
Protection against electric shock classes. Class I relies on basic insulation plus protective earthing; Class II on double or reinforced insulation with no earthing; Class III is supplied at safety extra-low voltage; Class 0 has basic insulation only; Class 0I has an earth terminal but a cord without an earth conductor and a plug without an earth pin.
