(hereinafter referred to as the BSMI) for the conduction of the type-approved batch-by-batch 
inspection (hereinafter referred to as the type approval) of wall-mounted ceramic washbasins 
(hereinafter referred to as the ceramic washbasins).

2. The terms used by these Directions are defined as follows:
(1) Type: the basic design of installation (i.e. to install a ceramic washbasin by using an expansible 
bolt, iron rack, triangular rack, or hook) and the material of the ceramic washbasins under the same 
brand. The ceramic washbasins of the same type shall be of the same brand, the same material, and 
the same design of installation.
(2) Serial type: the ceramic washbasins with different depths within 5% dimension tolerances under 
the same type, in accordance with column B of Table 1 of CNS 3220-3 “Sanitary ceramic 
ware –Washbasin”. If the depth of a ceramic washbasin is beyond the range listed in the above 
mentioned Table 1, the manufacturer shall classify the washbasin in accordance with CNS 3220-3.

3. A type test applicant shall submit the following technical documents and samples for each type 
and each serial type to the BSMI, Hsinchu Branch of the BSMI or Kaohsiung Branch of the BSMI 
or a designated testing laboratory recognized by the BSMI for a type test application.
(1) List of specifications (This should include dimensions and a profile map. For ceramic 
washbasins with different shapes under the same type, the profile maps of each shape shall be 
provided and the different dimensions shall be explained with a table.) 
(2) Color photographs (4X4 or larger) of finished products or a color catalog provided by the 
manufacturer
(3) A general description of the production processes
(4) Coding principle of product models
(5) A specimen page of the Chinese marking and precautions of the product
(6) An installation instruction manual and user guides
(7) Samples: two samples for each type and each serial type
The Chinese marking and precautions of the product specified in Subparagraph (5) of the preceding 
paragraph shall be marked in accordance with the requirements set out in Section 8 and 9 of CNS 
3220-3.
For the samples specified in Subparagraph (7), an applicant shall provide the washbasins with 
maximal horizontal dimensions within a depth range as the test samples.

4. The test items for the main type and the serial type of a type test are given as follows:
(1) The main type (all items to be tested): appearance, dimensions, water absorption rate, quenching 
resistance, crazing resistance, load test, and product marking.
(2) The serial type (key item to be tested): load test.

5. If a test report for CNS Mark is issued in accordance with the current version of CNS 3220-3, the 
type test report is allowed to be replaced by such test report.

6. The term of validity for a type approval certificate of the ceramic washbasins shall be in principle 
three years.

7. For ceramic washbasins subject to the type approval scheme, the obligatory inspection applicant 
shall apply to the BSMI or BSMI's branches that have jurisdiction over the applicant (hereinafter 
reffered to as the inspection authority) for the Commodity Inspection Mark and shall apply the Mark 
on the body of the commodity in accordance with the requirements set out in the Regulations 
Governing the Use of Commodity Inspection Mark.

8. The ceramic washbasins shall be marked in accordance with the requirements specified in Section 
8 of CNS 3220-3. In addition, the relevant precautions specified in Section 9 of CNS 3220-3 shall 
also be applied on the body of the commodities.

9. Once a ceramic washbasin has been granted type approval, the inspection authority should 
sample products at a possibility rate of one fifth. If an applicant has filed inspection applications for 
twenty consecutive batches and all the washbasins were found satisfactory, then the possibility rate 
for sampling the batches may be changed to one tenth. During the test, only the key items shall be 
tested. Two kinds for each main type (if fewer than two kinds, take one) and two pieces for each 
kind shall be sampled as per the different main types. For the ones not sampled, a document review 
should be conducted, and an on-site examination of the Chinese marking and the Commodity 
Inspection Mark will be conducted while necessary.

10. If an obligatory inspection applicant completed the relevant product marking in accordance with 
the Commodity Inspection Act and these Directions before sampling for testing or a batch-by-batch 
examination, and ten consecutive batches of the same products were found satisfactory by the 
inspection authority, the commodities not sampled could be exempted from the examination of the 
Chinese marking and the Commodity Inspection Mark for simplifying inspection procedures.

11. For those commodities that did not pass testing or the batch-by-batch examination, the 
simplified inspection procedures on the preceding two Clauses may be resumed after three 
consecutive batches have been filed for inspection and all have passed testing with batch-by-batch 
sampling.

12. If an inspection authority has been reported or there are doubts about the consistency of 
conformity with the inspection standard of the commodity that has been filed for inspection, then
