▍Vietnam MIC Certification

Circular 42/2016/TT-BTTTT stipulated that batteries installed in mobile phones, tablets and notebooks are not allowed to be exported to Vietnam unless  they are subjected to DoC certifctaion since Oct.1,2016. DoC will also be required to provide when applying Type Approval for end products (mobile phones, tablets and notebooks).

MIC released new Circular 04/2018/TT-BTTTT in May,2018 which stipulates that no more IEC 62133:2012 report issued by overseas accredited laboratory is accepted in July 1, 2018. Local test is necessity while applying for ADoC certificate.

▍Testing Standard

QCVN101：2016/BTTTT（refer to IEC 62133：2012)

▍PQIR

The Vietnamese government issued a new decree No. 74/2018 / ND-CP on May 15, 2018 to stipulate that two types of products imported into Vietnam are subject to PQIR (Product Quality Inspection Registration) application when being imported to Vietnam.

Based on this law, the Ministry of Information and Communication (MIC) of Vietnam issued the official document 2305/BTTTT-CVT on July 1, 2018, stipulating that the products under its control (including batteries) must be applied for PQIR when being imported into Vietnam. SDoC shall be submitted to complete the customs clearance process. The official date of entry into force of this regulation is August 10, 2018. PQIR is applicable to a single import to Vietnam, that is, every time an importer imports goods, he shall apply for PQIR (batch inspection) + SDoC.

However, for importers who are urgent to import goods without SDOC, VNTA will temporarily verify PQIR and facilitate customs clearance. But importers need to submit SDoC to VNTA to complete the entire customs clearance process within 15 working days after customs clearance. (VNTA will no longer issue the previous ADOC which is only applicable to Vietnam Local Manufacturers)

The safety of lithium batteries has always been a concern in the industry. Due to their special material structure and complex operating environment, once a fire accident occurs, it will cause equipment damage, property loss, and even casualties. After a lithium battery fire occurs, the disposal is difficult, takes a long time, and often involves the generation of a large amount of toxic gases. Therefore, timely fire extinguishing can effectively control the spread of the fire, avoid extensive burning, and provide more time for personnel to escape.
During the thermal runaway process of lithium-ion batteries, smoke, fire, and even explosion often occur. Therefore, controlling the thermal runaway and diffusion problem has become the main challenge faced by lithium battery products in the process of use. Choosing the right fire extinguishing technology can prevent the further spread of battery thermal runaway, which is of great significance for suppressing fire occurrence.
This article will introduce the mainstream fire extinguishers and extinguishing mechanisms currently available on the market, and analyze the advantages and disadvantages of different types of fire extinguishers.
Types of Fire Extinguishers
Currently, the fire extinguishers on the market are mainly divided into gas fire extinguishers, water-based fire extinguishers, aerosol fire extinguishers, and dry powder fire extinguishers. Below is an introduction to the codes and characteristics of each type of fire extinguisher.
