Vietnam: What are the regulations on declarations of conformity of industrial explosive materials - Water Resistant ANFO explosives?

According to subsection 9 Section III of the Vietnam National Technical Regulation QCVN 12 - 9:2022/BCT stipulating the declarations of conformity for industrial explosive materials - Water Resistant ANFO explosives as follows:

- The declarations of conformity of domestically produced water-resistant ANFO explosives must be based on the certification results of a certifying organization that has registered its field of operation as prescribed in Decree 107/2016/ND-CP dated May 1st. 7 in 2016 of the Government regulating the business of conformity assessment services (hereinafter referred to as Decree No. 107/2016/ND-CP); Decree No. 154/2018/ND-CP dated November 9, 2018 of the Government amending, supplementing and annulling a number of regulations on investment and business conditions in the field of state management by the Ministry of Science and Technology and a number of regulations on specialized inspection (hereinafter referred to as Decree No. 154/2018/ND-CP) or recognized under the provisions of Circular No. 27/2007/TT-BKHCN dated 31 October 2007 of the Minister of Science and Technology guiding the signing and implementation of Agreements and agreements on mutual recognition of results of conformity assessment (hereinafter referred to as Circular No. 27/2007) /TT-BKHCN).

- The declarations of conformity of imported water-resistant ANFO explosives must be based on the certification results of a certifying organization appointed by the Ministry of Industry and Trade according to the provisions of Circular No. provisions of Circular No. 27/2007/TT-BKHCN.

- Certificate of conformity

Certification of conformity for domestically produced and imported water-resistant ANFO explosives is carried out according to method 5 “Testing typical samples and evaluating the production process; supervision through testing samples taken at the place of production or on the market or imported consignments in combination with assessment of the production process” or method 7 “Testing and evaluating batches of products and goods” at the production facilities as prescribed in Clause 1, Article 5 of Circular No. 28/2012/TT-BKHCN.

- Testing for certification of conformity must be carried out by one of the following organizations:

+ Testing for domestically produced water-resistant ANFO explosives: Organize the test according to the provisions of Decree No. 107/2016/ND-CP, Decree No. 154/2018/ND-CP or test organization The Ministry of Industry and Trade shall appoint according to the provisions of Circular No. 36/2019/TT-BCT or an organization recognized under the provisions of Circular No. 27/2007/TT-BKHCN.

+ Testing for imported water-resistant ANFO explosives: The testing organization is appointed by the Ministry of Industry and Trade according to the provisions of Decree No. 74/2018/ND-CP or the organization is recognized according to the provisions of Circular No. 27/2007/TT-BKHCN.

- Order, procedures, and documents for announcement of regulation conformity

The order, procedures and dossiers of declaration of conformity for domestically produced and imported water-resistant ANFO explosives comply with the provisions of Circular No. 36/2019/TT-BCT.

Vietnam: What are the technical requirements for the test method for industrial explosive materials - Water Resistant ANFO explosives?

Pursuant to Section 7.2, Subsection 7 Section II, Vietnam National Technical Regulation QCVN 12 - 9:2022/BCT stipulating technical requirements for testing methods for water-resistant ANFO industrial explosives such as:

- Explosion rate measuring cable and signal cable must not be crushed or broken;

- The total impedance of the burst rate measuring cable used is from 50 Ω to 3 000 Ω;

- The detonation delay time at the boreholes increases in the direction from the beginning of the first borehole explosion rate cable to the end of the borehole burst rate cable connected to the signal cable to the MicroTrap machine;

- For boreholes using a detonator, in order to ensure that the amount of explosive in the borehole is detonated completely without affecting the rock breaking criteria, it is required that the depth of the borehole measure the explosion rate from 10 m to 15 m. For a borehole with many detonating blocks, it must be calculated so that the detonation delay of these detonators increases from the bottom of the hole or two detonators must be combined (if two detonators are used) to drop. down from the bottom of the borehole from 0.5 m to 2 m depending on the height of the column;

- Measurements are performed simultaneously with 3 adjacent boreholes.
