Introduction: Market Supervision Bureau: Household gas appliances, wires and cables, switches and sockets and other electrical accessories fire protection product safety publicity, when purchasing wires and cables, switches and sockets, stoves and other electrical accessories fire products, must see whether the product has the "CCC" compulsory certification mark, please do not buy products without compulsory certification marks.
Market Supervision Bureau: Safety promotion of fire protection products for household gas appliances, wires and cables, switches and sockets and other electrical accessories:
In order to prevent the quality and safety accidents of household gas appliances, wires and cables, switches and sockets and other electrical accessories, and effectively protect the safety of people's lives and property, Sinan County Market Supervision Bureau issued the following consumer warnings for the purchase and use of fire protection products of household gas appliances, wires and cables, switches and sockets and other electrical accessories in our county:
When buying wires and cables, switches and sockets, stoves and other electrical accessories and fire-fighting products, you must see whether the product has the "CCC" compulsory certification mark, and please do not buy the product without the compulsory certification mark.
Do not buy products without the name of the manufacturer, factory address, product certificate and other "three nos" and products eliminated by the state.
Please correctly use switches, sockets, gas cookers and other electrical accessories for fire-fighting products.
First, see the product identification method
1.Household gas appliances (including gas cookers, household gas rapid water heaters and gas heating water heaters) with a production date before October 1, 2020 shall be marked with a QS logo or production license number.
2.Household gas appliances with a production date after October 1, 2020 shall be marked with the CCC compulsory certification mark.
3.After January 1, 2022, it is forbidden to sell household gas cookers (produced after October 1, 2020) without the CCC compulsory certification mark
4.Look for product standards:
Before January 1, 2022, the product standard for household gas cookers is GB 16410-2007 or GB 16410-2020.
After January 1, 2022, the product standard for household gas cookers is GB 16410-2020, and the production and sale of household gas cookers without this product standard are prohibited.
Gas heating water heater product standard: GB 25034-2020.
Household Gas Rapid Water Heater Product Standard: GB 6932-2015. Understand the service life According to the "Safety Management Rules for Household Gas Burning Appliances" issued by the state: from the date of sale, the safe service life of gas water heaters using liquefied petroleum gas and natural gas should be 8 years; The safe service life of water heaters using artificial gas should be 6 years.
At the end of its useful life, even if it still looks "intact", consumers are advised to force scrapping for their own safety. According to the living habits and the number of family members, determine the purchase of household gas stoves with corresponding heat load values, and pay attention not to use them with excessive heat load.
5.Choose a regular channel to choose a gas cooker correctly should be divided into: checking, pressing, selecting, and looking at four steps.
Check whether the business has complete licenses, and try to choose regular places such as large shopping malls and specialty stores to buy;
Second, check whether there is a safety mark, factory name, factory address and the instruction manual consistent with the product, and do not buy low-cost inferior products or even "three no" products cheaply. **Press the surface of the appliance to see if there is no obvious depression, and whether the material and assembly quality are normal.
Third, choose whether the type of gas applicable to the gas appliance is consistent with the type of gas used at home.
Fourth, look at the rated heat load and thermal efficiency of the product on China's energy efficiency label, the smaller the energy efficiency grade number, the better the energy-saving effect, and try to choose a first-class energy efficiency product; The cooktop must be a safety cooker with an automatic flame-out protection device, and the gas water heater must be a safety water heater with a strong exhaust or balanced type (including outdoor type).
* Consumers are requested to keep their eyes open, actively refuse to buy, use and eliminate in-line gas water heaters and household stoves without flame-out protection devices in a timely manner. If you find illegal acts, please call the market supervision complaint report **12315 in time.
2. What are the dangers of using inferior wires?
How to tell?
What are the dangers of using low-quality wires? Inferior wires will cause insulator breakage, expose live conductors, and easily cause electric shock hazards, which will cause short circuits, power outages, damage to electrical equipment, and even serious consequences such as disasters. So how to identify the authenticity of the wire.
1. Look carefully at the printed words on the label, the handwriting is blurred. It refers to the printed words on the label and the insulating outer skin, if there are typos or printing depths.
First, the words are blurred, and attention should be paid to them.
2. Twist the insulating skin by hand, fade the color, and drop the quality of the word. It refers to rubbing the insulating skin with fingers, some inferior insulated wire skins are easy to fade, especially the red wire will appear this problem, after rubbing, the fingers leave the color of the wire skin or the words on the leather are wiped off is generally inferior wire.
3. Scratch and pinch the line with your fingernails, and the line is generally inferior to the skin. It refers to scratching and pinching the insulating outer skin with a fingernail, and the one that can be scratched and pinched off is generally an inferior line.
4. Bend the insulated wire repeatedly, and break it three to four times. It refers to repeated bending of insulated wires, and the insulation layer of inferior wires is generally of poor material, and the insulation layer will break after bending 3-4 times.
5. Ignite the wire insulation layer with fire, and the open flame wire spontaneously combusts. It refers to igniting the insulation layer, and it is an inferior wire that can spontaneously combust after leaving the open flame.
6. Aluminum and copper are commonly used in the core of the wire, and the color becomes dark and the luster is light. It refers to the color of the core, and the color of the inferior line is gray and has no metallic luster.
7. Measure the inner diameter and outer diameter, and weigh it. It means that if the above 6 methods can not be determined, the outer diameter of the insulated wire and the diameter of the core can also be measured, the allowable error is 10%, and if the measured value exceeds the allowable error, it is basically an inferior insulated wire.
Tips:
When purchasing wire products, first observe the cross-section of the wire, the surface of the copper core or aluminum core of the qualified product should have a metallic luster, and the surface of the blackened copper or the surface of the whitish aluminum indicates that it has been oxidized, mostly inferior materials; If the plastic that wraps the wire is easily peeled off, there is a possibility that the plastic is not strong enough; If possible, the plastic on the surface of the wire can be ignited, and if the flame does not self-extinguish or self-extinguishes for a long time, it means that the flame retardant factor of the wire may not meet the standard. In addition, many household appliances belong to the 3C compulsory certification products, and when buying such products, you should check whether there is a "3C" certification mark and the factory name and address.
3. The municipal supervision department reminds you
Don't use this "universal socket" anymore!
This kind of three-hole universal socket has been banned by the country, and long-term and repeated use may lead to fire!
Why is it explicitly banned by the state?
On June 1, 2010, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Standardization Administration of the People's Republic of China began to enforce the new national standard, and the production of universal hole sockets has been expressly prohibited to enforce the new national standard combined jack, which is the five-hole socket on the right side of the figure below.
Because the old three-pin socket has certain defects, that is, the contact area between the plug and the socket is small, and there will be a fire hazard after long-term use.
The old universal socket has been eliminated for 6 years, and it has been replaced with a 5-hole universal socket of the new national standard
How dangerous is it to use an old socket for a long time?
If you use the old universal socket for a long time, you may burn the socket hole.
Fourth, some burned the electrical appliances in the home
How to choose an outlet?
Step 1: Weigh the weight
There are many copper wires, thick copper sheets, and tight plastic shells used inside the sockets that meet national standards, so the weight is heavier, while the unqualified sockets will obviously feel much lighter when cutting corners.
Step 2: Listen to the sound
You can repeatedly press the socket switch several times, the qualified socket opens and closes freely and the sound is crisp, and the unqualified socket feels stiff and easy to stuck.
Step 3: Try the feel
The plugging and unplugging feel of each hole is moderate and elastic, and the plugging and unplugging feel of each jack is the same, and the plugging and unplugging strength of the unqualified socket is too loose or too tight, the elasticity is poor and easy to loosen, and each hole can also obviously feel different.
Step 4: Look at the hardness
The power cord of the qualified socket feels moderately soft and hard, and the connection with the socket is solid and reliable, while the power cord of the unqualified socket feels soft, and the connection with the socket is not firm, and it is easy to pull off.
Final reminder: Please look for the "five-hole socket" instead of the "three-hole universal socket" when buying the first seat, the three-hole has been eliminated by the state!
For the safety of your family's lives and property, don't really save some money to buy low-quality sockets. **contain**: Sinan market supervision).
