At the proposal of the Chairman of the National Standardization, Metrology, and Quality Control Committee;

The Minister of Science and Technology issues this Circular amending, supplementing, and abolishing certain provisions of legal documents issued by the Minister of Science and Technology in the field of standards, measurement, and quality.

At the request of the Chairman of the National Standardization Measurement Quality Committee;

The Minister of Science and Technology issues the Circular amending, supplementing, and abolishing some Articles of the regulatory legal documents issued by the Minister of Science and Technology in the field of standardization, measurement, and quality.

Article 1. Amend and supplement some articles of Circular No. 22/2013/TT-BKHCN dated September 26, 2013 of the Minister of Science and Technology on measurement management in gold trading and quality management of jewelry and decorative gold circulating in the market as follows:

1. Amend and supplement Clause 1 of Article 4 as follows:

"1. Scales used to determine the weight of gold or gold content in transactions between organizations and individuals must meet the following requirements:

a) The measuring range and accuracy must be appropriate for the weight of gold to be measured. The scale capacity must be consistent with the value of the division of verification (e) specified in Table 1.

Table 1

b) Must have been verified at a verification organization recognized or designated in accordance with the law on measurement; the verification certificate (verification mark, verification label, verification certificate) must still be valid."

2. Amend and supplement Clause 3 of Article 4 as follows:

"3. The weight of gold in transactions with organizations and individuals or during inspections and checks shall not be less than the declared weight. The limit of error of the result of the weight measurement must comply with the requirements specified in Table 2.

Table 2

The limit of error of the weight measurement result (m) not specifically provided in Table 2 shall be determined as follows:

a) For m < 30 g, the limit of error (S) is calculated according to the following formula and rounded to one (01) value of the division of verification (e) of the scale used.

Example 1:

The result of the weight measurement of a gold ring is 7.5 g (2 tael) when using a scale with e = 1 mg, the limit of error (S) is:

b) For 30 g < m < 6000 g, the limit of error (S) is calculated according to the following formula and rounded to one (01) value of the division of verification (e) of the scale used:

In the formula above:

S: maximum allowable error;

m: weight of gold;

: two consecutive weights of gold in Table 2 corresponding to the number i and i+1 ensuring the condition ;

: limit of error in Table 2 corresponding to ;

Example 2:

The result of the weight measurement of a gold necklace is 86 g (m = 86 g) when using a scale with e = 1 mg, from Table 2, we see that 50 g < 86 g < 100 g.

Therefore:

The limit of error (S) is:

c) For m > 6 kg, the limit of error (S) is calculated by multiplying the measurement result by 0.0175% and rounding to one (01) value of the division of verification (e) of the scale used.

Example 3:

The result of the weight measurement of a gold bar is 10 kg when using a scale with e = 100 mg, the limit of error (S) is:

S = (10 x 0.0175%) kg ~ 1.8 g"
