Note 1:

If the EMC critical components model of the non-representative sample is different from that of the

representative ones, an EMC variation test of supplementary samples should be carried out

according to the requirements of this appendix. Under the premise of representative samples and

supplementary samples covering the EMC performance or the EMC critical components of all the

models/types, effort should be made to minimize the quantity of the supplementary samples and the

EMC variation test items. If the components meet the conditions of the simplified procedure, the

EMC variation test can be exempted, but the producer (manufacturer) shall report to the certification

body for the record.

Note 2:

Requirements for the change of EMC critical safety components are as follows:

1.1 The change of components in category A

The change of components within category A shall be approved by the certification body.


of 52 Ref. No. CNCA-01C-016: 2010




1.2 The change of components in category B

The simplified procedure is applicable to the change of components within category B if the

requirements in 1.3 of this appendix are met, otherwise the change shall be approved by the

certification body.

1.3 Simplified procedure

The simplified procedure means the certification clients only need to report to the certification body

for the record if the critical components are changed.

Conditions for the application of the simplified procedure:

1) The critical components changed belong to category B.

2) Components within category B which are listed in the Catalogue of Products Subject to the

Compulsory Product Certification system shall obtain valid compulsory certificates (including EMC

certification). Producers (manufacturers) of other components within category B shall provide EMC

test report of a complete appliance issued by the laboratories which are accredited by CNAS to

conduct relevant standards.

3) There shall be a certification technical principal, who is appointed / delegated by the producer

(manufacturer) and assessed and approved by the certification body,.

4) The producer (manufacturer) must have good commercial credibility.

The change of components in category B which cannot meet the requirements above shall be

approved by the certification body.

The change of the critical components to which simplified procedure is applicable shall be approved

by the certification technical principal and the records shall be kept.

If the change of components in category B, to which the simplified procedure is applicable, is

misreported or is not reported, the change would be considered as invalid and as unilaterally

changing critical components. Once such any illegal change is discovered, the certification body

shall take measures depending on the degree of seriousness according to Regulations for

Compulsory Product Certification, Implementation Rules for the Cancellation, Suspension and

Withdrawal of Compulsory Product Certificates and relevant requirements of the certification body.

Providing false information about the change would be considered as unilaterally changing critical

components and the certification body shall revoke the certificates.

Testing Requirements for Factory Quality Control

of Household and Similar Use Appliances

Note：

(1) Routine test is 100% test conducted on the products at the end of the production line. Generally,

after routine test, no further process is needed except for packing and labelling. Verification test is a

kind of sampling test to check the continuous compliance of the products to the standard

requirements;

(2) Routine tests could be done through fast and equivalent methods which have been verified;

(3) Verification test should be performed according to the requirements of the standards. Verification

tests may be entrusted to the testing laboratories authorized by CNAL if the factory is not capable of.

Annex: Test methods of routine test (methods in this annex are recommended)

Method 1: Earthing resistance

For Class I appliances, get at least 10A current from a AC power supply (no-load voltage up to12V)

and let the current go through each metal easy-touched earth parts and earth terminals (for Class OI

and I appliances intending to connect to fixed wires permanently) or earth bolt of power cord plug or

its earth contacts or earth bolt of input jack in the appliance (for other appliances), and then measure


of 52 Ref. No. CNCA-01C-016: 2010




the voltage between its ends, and calculate the resistance to earth according to the current and

voltage. The resistance to earth shall not exceed:

-- For appliance with soft power cord, the resistance is 0.2 Ω or 0.1 Ω + R (R is the resistance of wire

between earth plug of power cord and earth terminal of the appliances);

-- For other appliances, the resistance is 0.1 Ω.

Note:

1. The measuring position is selected by the manufacturer according to the manufacturing technique.

2. During measuring, the contact resistance between the point of measure pen or rod, and metal

parts shall not affect test results.

Method 2: Electric strength

Insulation of the appliance should be able to withstand a sinusoidal voltage with 50 Hz or 60 Hz

frequency and 1 second duration. The minimum test voltage values (RMS) and applied positions are

carried out according to the following table.

The position applied by test voltage

——

* (1) Appliance of Class 0 is exempted from this test;

(2) The appliances with type II structure of Class 0I, I, if not applicable, are exempted from this

test.

Notes:

(1) During test, it should ensure that the test voltage is exerted on all relevant insulation parts, such

as: electric heating components controlled by relay.

(2) There should be a current-sensitive appliance in test circuit. If testing circuit current exceeding a

certain value, it should trip and alarm the unqualified result through sound or light (recommended


of 52 Ref. No. CNCA-01C-016: 2010




value is 5 mA and, if necessary, this value can be increased, but should not exceed 30 mA), and the

step-up transformer should have sufficient capacity to maintain the required test voltage value up to

tripping current.

(3) DC voltage can be used instead of AC voltage for insulation test, but the test voltage should be

1.5 times the value in the above table. The AC voltage with maximum frequency as 5 Hz can be

regarded as DC.

Method 3: Additional routine test items for fans

Test method for input power

The total input power shall be measured under rated voltage, maximum load or conditions stipulated

by the manufactory.

Methods 4: Additional routine test items for household washing machines

Test method for interlock of door in tumble dryer

During the test, the dryer, carrying rated load, shall operate under rated voltage or maximum value of

rated voltage. Then open the door manually, the power supply of motor can be disconnected

automatically (tumbling-box stop operating) before opening the door more than 75 mm; in case that

the door is opened 75 mm, the tumbling-box is unable to operate even activate the working button.

Brake test method for washing machine, spin extractor

For tumbling-box washing machine with top opening door or side opening door, if the door or cover

can be opened during operating, the power supply of motor shall be disconnected and the

tumbling-box shall stop operating before the opening more than 50mm.

For fully automatic impeller washing machine and spin extractor with top opening door during

extracting, the power supply shall be disconnected and the cylinder shall stop operating in case that

the door or cover open 75mm.

For spin extractor and tumbling-box washing machine with front opening door, if the door or cover

can be opened during operating, the power supply shall be disconnected and the tumbling-box shall

stop operating in case that the door or cover open 12mm.

During extracting, the speed of cylinder or tumbling-box with rated load shall be able to fall below 60

r/min within 7 seconds in case that the cover or door open 50mm (if the door or cover can be

opened).

Method 5: Additional routine test items for storage water heaters and instantaneous water

heaters

Test method for structure

Water tanks shall be able to withstand pressure test using water, air or other gases, the pressure is:

-- 0.7 MPa (for closed storage water heaters and closed instantaneous water heaters);

-- 1.1 times the value of rated pressure (for closed storage water heaters and closed instantaneous

water heaters with rated voltage more than 0.6 MPa);

-- 0.3 MPa (for storage water heaters with flume supplying water)

-- 0.15 MPa (for storage water heaters and instantaneous water heaters with open outlet)

-- 0.03 MPa (for storage water heaters with water tank)

Note: Test can be implemented on a separate container.

Method 6: Additional routine test items for liquid-filled room heaters

Test method for structure

The liquid-filled containers of the appliance shall be able to withstand pressure test using water, air

or other gases, the pressure is:

-- For oil-filled heaters, the pressure is 0.2 MPa;

-- For other liquid-filled room heaters with operating pressure more than 0.2 MPa, the pressure is 1.1

times the value of operating pressure.
