According to the regulations of the Ministry of Science and Technology, products classified as Luminaires with surface temperature limits under QCVN 19:2019/BKHCN must undergo procedures for Testing, Certification of Conformity, and/or Declaration of Conformity, and must be labeled with the conformity mark (CR) before being placed on the market.

Regulations regarding lamp classification, scope of application, or lamps excluded from the scope for Luminaires with surface temperature limits will be provided and clarified by Phuc Gia Testing Laboratory in the article below.

1. What are Luminaires with surface temperature limits?

Luminaires designed for use in locations where surface temperature limits are required due to the risk of combustible dust accumulation on the luminaire, but where there is no atmospheric risk. These luminaires are for use with electric light sources with a supply voltage not exceeding 1000V.

2. What is the scope of application for Luminaires with surface temperature limits under QCVN 19:2019/BKHCN?

Special temperature limits apply to luminaires typically covered by combustible dust, for example, in areas where textiles are processed or stored and in spaces where combustible dust accumulates—such as pigments, sawdust, grain dust, flour, and textile fibers—accumulated in large quantities but without an explosion risk.
