The new EU standard luminaire standard EN60598-1:2015 will end the transition period and be enforced on October 20, 2017. This version has more technical revisions than the previous EN60598-1:2008, including some important technical changes. The biggest change is the inclusion of photobiosafety for the first time in mandatory standards.
The standard stipulates that if a luminaire including LEDs, metal halide lamps and some special tungsten halogen lamps that do not exempt the retinal hazard assessment source is used, it should be based on IEC/TR62778:2012 "Photobiosafety Blu-ray damage assessment application for light sources and luminaires". 》Evaluation, and it is not appropriate to use a light source with a blue light hazard group greater than RG2.
Taking 2016 as an example, the value of China's LED lamps exported to the EU is as high as more than 2 billion US dollars. Once the product quality is not up to the standard requirements, it will be severely punished by the EU market for spot checks and notifications, which will result in economic losses and even blacklisted.
The effect of blue light on the human eye
Light in nature consists of spectra of different colors, and different wavelengths visually present different colors. Physical studies have shown that the shorter the wavelength, the higher the energy and the stronger the penetrating power. Therefore, people will pay special attention to the harm of the short-wavelength blue light to the human eye.
According to industry insiders, blue light may have three effects on the human eye: First, excessive blue light content may cause increased visual fatigue; second, may have an impact on eye physiological development; third, long-term in such light environment Homework, the possibility of inducing macular degeneration in the elderly will increase.
Therefore, in order to protect the safety of domestic consumers, and at the same time effectively prevent blue light hazards, the EU has taken the lead in raising the level of photobiosafety to the level of mandatory standards. It is expected that other countries and regions will gradually follow suit.
Specific requirements for photobiosafety
The requirements of photobiological requirements in the new edition of the standard are mainly reflected in the following two aspects: one is to increase the section 3.2.23 not to look at the logo of the bright light source; the second is to increase the section 4.24 photobiosafety.
Photobiosafety requirements include radiation intensity, radiance, etc., and hazard grading of products based on test data, including Category 0 hazard (RG0 exemption level), Class 1 hazard (RG1 low risk), Category 2 hazard (RG2 medium risk) ) and 4 types of danger (RG3 high risk) a total of 4 levels.
In addition, the new version of the standard also introduces IEC/TR62778:2012 "Photobiosafety Blu-ray Damage Assessment Application for Light Sources and Luminaires", which specifically addresses retinal blue light hazards as follows:
Blu-ray hazard does not apply when the luminaire uses RG0 unrestricted or RG1 unrestricted light source or the luminaire used after complete assembly is RG0 unrestricted or RG1 unrestricted level;
For fixed luminaires, the distance Xm of the boundary between luminaires RG2 and RG1 shall be found in accordance with the additional assessment of IEC/TR62778 and shall be marked and stated;
More than one type of dangerous mobile and hand-held luminaires need to be marked with the “Do not stare at light source†sign.
To this end, the inspection and quarantine department reminds the relevant lighting manufacturers that export to the EU:
First, it is necessary to organize technical personnel to study and study the new standards in advance, seize the first-mover advantage, and grasp the new changes as soon as possible, especially the first-time photobiosafety requirements.
The second is to modify or design products that meet the requirements of the new standards, and contact qualified third-party laboratories as soon as possible to do product inspection and testing, and obtain a valid certification before export, before the end of the EU transition period. Be prepared to respond.
The third is to grasp the quality control of the whole process in actual production, to ensure that the quality of each batch of goods meets the requirements of the importing country, and to avoid the export of products due to quality defects.
·Basic precautions
Do not put expensive oil into low-quality cartridges to avoid wastage. Most pre-filled oil cartridges have the so-called 510 thread. The oil cartridge screws onto a rechargeable battery. Some of these batteries have buttons and some heat up automatically when you pump the oil. Some batteries have multiple temperature settings and some heat up to a preset temperature; these features need to be known in advance.
·Cleaning notes
Use a suitable cleaning tool to clean them, such as activated charcoal or dried tea leaves in a used pipe to absorb the oil. It is important not to use alcohol or other boiling water to clean the pipe, and to wait until it has cooled down completely before cleaning. Otherwise, the hot stem will come into contact with the watery liquid and cause the mouthpiece tenon to loosen, thus shortening the life of the 510 cartridges.
This is what you should be aware of when using 510 cartridges. At the same time, when using 510 cartridges, there are still some vaping tips, for example, when using them, be careful not to suck too hard, will not produce smoke. When you inhale too hard, the smoke is sucked directly into your mouth and not atomized by the atomizer, so gently inhaling is more powerful and gives you a better vaping experience.
