referred to as BSMI) has established these directions 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 the Chinese National Standard 
(hereinafter referred to as the 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 the CNS.

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 product Chinese marking and precautions
(6) An installation instruction manual and user guidelines
(7) Samples: two samples for each type and each serial type
The product Chinese marking and precautions specified in Subparagraph (5) of the preceding 
paragraph shall be marked in accordance with the requirements set out in Section 8 and 9 of the 
CNS 3220-3.
For the samples specified in Subparagraph (7) of Paragraph 1, 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 CNS Mark test report is issued in accordance with the current version of the CNS 3220-3, the 
type test report is allowed to be replaced by the CNS Mark test report.

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

7. The obligatory inspection applicant of type-approved ceramic washbasins shall apply for the 
Commodity Inspection Mark to the BSMI or its Branches with jurisdiction over the applicant 
(hereinafter referred to as the inspection authority) when an inspection application is filed, 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 the CNS 3220-3. In addition, the relevant precautions specified in Section 9 of the CNS 3220-3 
shall also be applied on the body of the commodities.

9. Once a ceramic washbasin has been granted type approval, inspection authority should sample 
products at a possibility rate of one fifth. When sampling for testing, if an applicant has filed 
inspection applications continuously up to twenty batches and all the washbasins were found 
satisfactory, then the possibility rate for sampling the batches to be filed should be one tenth. During 
the test, only the key item 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 product 
Chinese marking and the Commodity Inspection Mark will be conducted while necessary.

10. If an obligatory inspection applicant has finished the relevant product marking in accordance 
with the Commodity Inspection Law and these Directions before sampling for testing or a 
batch-by-batch examination, filed ten continuous batches of the same products, and made sure all 
the products have passed testing or examinations by the inspection authority, then the commodities 
not sampled could be exempted from the examination of the product 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 
continuous 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 
the commodity maybe sampled for an all-item test.
