Explosion proof lighting led are suitable for use in hazardous areas where flammable gases and dust are present. They can effectively prevent arcs, sparks and high temperatures generated inside the lamps from igniting flammable gases and dust in the surrounding environment. Therefore, in the factory production, it is necessary to comply with strict regulations, and do various aging tests before leaving the factory. So what are the projects for the explosion proof lighting led aging test?Explosion proof lighting led aging test projects include:Fast UV aging test:ASTM, AATCC, ISO, SAE J, EN, BS, GB/TXenon lamp aging:SAE J, ASTM, ISO, GB/T, PV, ULCarbon arc aging:ASTM, JIS DOzone aging:ASTM, ISO, GB/TLow temperature test:IEC, BS EN, GBHot air aging:ASTM, IEC, GB, GB/TConstant temperature and humidity test:ASTM, IEC, ISO, GB, GB/TCold and hot wet cycle test:BS EN, IEC, GBColor difference after aging:ASTM D, ISO, AATCCGloss change after aging: ASTM DMechanical properties after aging;Evaluation after coating aging;Salt spray test:ASTM B, ISO, BS, IEC, GB/T, GB, DINAcid Salt Spray Test:ASTM G, DIN, ISO, BSCopper ion accelerated salt spray test:ASTM B, ISO, BS, DINCyclic Salt Spray Test:ASTM, ISO, SAE J, WSK, GMWater mist experiment:ASTM D

Do you agree with this partial list of Democratic led failures?
UN is not a failure; it's done tremondous good throughout the world. The Fed is not a failure; it's prevented massive amounts of suffering. The New Deal was not a failure; it prevented massive amounts of suffering. Uh, dunno what you have against âalphabet soupâ agencies. Many of them have done much good -- from making sure our food does not kill us, to helping disaster victims. You seem to think that preventing death and suffering are BAD things, rather than GOOD things. Not all such agencies were created by Dems. Social Security -- prevented massive suffering and needless death. Vietnam was not LBJ's - it actually started with Eisenhower, and Nixon extended it; they are Republicans. Nam was wrong from the start. Welfare -- prevents massive suffering. skipping because I am bored with this idiocy Uh, there's IS not âgovernment-run health careâ -- the people who keep telling you this have been lying to you. No one with any brain believes everything proven liars tell them. Failure to reform health care will bankrupt every family, business, and level of government; most Americans do not want tens of thousands to continue to die every year from preventable health problems. Only sub-humans think that's a good thing.
what is the best picture settings for my 32" led vizio smart tv?
From experience, the factory presets are pretty good and cover the wide range of viewing needs. Unlike the old days of television, the need to tweak the picture with the individual controls is not really needed unless you have a very special lighting condition that you need to compensate for. I can not help but wonder if the problem is with the source? If you are viewing streaming video, do not expect wonders.
What unique characteristics and/or special attributes have you noticed or sensed in yourself throughout lifeu2019s journey that has led you (at any time) to believe that you may not be human?
That's pretty tricky. It's a view that most do not like to hear, though it makes some sense to me. Basically, I kind of suspected, some years back, that some cases of de ja vu just might have been glimpses of a former life. I am talking about a space between a previous life and an impending afterlife, which would be this existence we are in at this moment. Some call it the Mandela Effect, though I kind of suspect that we all may have slipped into this plane of existence, as another step towards an afterlife. I know it's not Biblical, but it kind of does feel like some kind of transition between 2 planes. Many complain that time goes by faster now, and in reality I believe it as well, which is another hint that we are not where we think we are. Well, it gets more and more complicated from there, and I am not trying to write a book for Quora

It's a good choice.You can use it.Do not worry
How bad of a shape is the U.S right now? Is it as bad as we're led to believe?
We've seen worse. Right now there's just a lot of political agitation going on. Things are being stirred up so that people will think it's Trumps fault and Biden will be elected. But it's the left stirring things up. Racism has never been lower in this country. Opportunities have never been better. Things may get violent here and there but it will all pass
I found out that my grandma cheated on my grandpa with his best friend which led to his friend committing suicide, how do I come to terms?
This will be a lot easier for you if you stop making the wrong assumption that Harry committed suicide because of your grandpa. This is not even possible! When an older person commits suicide, it's never because of one thing. Cheating has been around since the dawn of time, and nobody commits suicide just because of that. Things happened with Harry starting in his childhood that contributed to this. It's fine to be angry with your grandma, because she made some odd life choices. She married an abusive man, she stayed with him, and then she cheated w/ his best friend. But do not blame her for Harry's suicide. That was a decision he made on his own.
This guy led me on!?
you should talk to him. a real one on one talk . ask him why he did it? why in the world you deserved something like that... and if he has no good explanation. just call him an *** and leave
Why do people think led zeppelin is the best band ever?
I for one do rank them right up in the top 3. We all have our personal opinion, and I will not knock yours. They did give credit where credit is due. All were extreemly talented musicians. I am glad we have this forum to have these differences of opinion. Have a gresat day !

What are some major events in history that have led to the overpopulation of our planet?
Events? Mathematics (arithmetic progression specifically) is enough to explain exponential growth in population. Events will only be , at best , minimal or at worst- a moot point. Attitudes can be shaped by events- 1. Invention of electric lightbulb, and television- contributed to general comfort. 2. industrial age- that ushered in heating in homes, light as mentioned, indoor plumbing, indoor kitchens 3. agricultural streamlining- food became accessible. 4. wars- took away lives- is the historical depopulation exercise. Once one of those is over and relative calm descends on the nation- the remaining population attempts to regroup and regenerate (repopulate actually) 5. Religion- some religions forbade birth control 6. Societal restrictions/laws against abortion 7. Invention of birth control devices 8. sexual revolution
When you see a homeless person do you ever wonder what decisions and choices led him to that point?
No, but I do wonder how they can continue to live in the way they do. It seems so useless to waste a life in that way, but we all have choices and that's what some of them chose, not all just some. Whatever it makes me realize how very lucky I am.
Do you think it's easier to do your drawings in led, graphite, charcoal or color?
I actually do not like doing my drawings in graphite anymore. I like to work big and it's far easier to cover ground using other mediums. If you are looking for platinum blonde you should try working with pastels. They make a cream color. You can also buy paper in the color you are looking for. I am pretty sure they make cream colored paper...like your âplatinum blondeâ
why does led zeppelin sing muslin songs?
Maybe they liked to sew in their spare time. You might want to consider getting sober so you can pay attention to the lyrics.
All my life, all I ever did was what everyone expects me to do. I never have a say in big decisions in my life and this has led me to depression. All I ever do is cry, I don't know how to tackle my emotions. Any adviu0441e?
I would forget about those big decisions. When it comes down to it there are so many factors that few of us are truly in control of those. Focus on the small decisions. You can tackle some of those. Move up to the slightly less small choices, and eventually I think you will find yourself at least having an effect on all the decisions in your life. You probably wo not be in total control, but I hope you wo not feel so out of control. And it all comes from deciding which cake to have with your coffee. Or maybe something more healthy than cake
i have a digital camera Nikon* its not work now just red &green led flashing?
When they are BOTH blinking, it means the battery is exhausted and you need to replace or recharge the batteries. I have several Nikon point and shoot cameras and this is right from the manual, so please ignore those who are speculating. Just chage the batteries
soldering led's!! plz tell how to do it!!!!?
I am not sure exactly what you are asking. LEDs are directional, meaning they will only work if you solder the anode (negative end) and cathode (positive end) to the appropriate poles of the voltage source. Resistors are usually bidirectional, meaning it does not matter which end you solder to a particular wire. I do not see why your particular configuration would cause a problem. I've even wired LEDs in series with each other using no resistors--just making sure that the total forward voltage was not too high for any of them--with no problem
In your opinion, do people contribute to the problem of global warming as much as we are led to believe?
It's a scientific issue, so I go with the overall opinion of the scientific community. Wiki has a nice summary of the statements of organisations, and I did some of my own research and read other summaries. The overwhelming conclusion of trustworthy scientific organisations is in favour of the theory that humans are the most important driver of recent global warming. I've looked at the science when I've had time and it looks solid to me (I am a physicist). Why anyone would choose to believe politicians, the media or lobby groups over scientists is way beyond my understanding. Some scientists do disagree, but from what I have found they are overwhelmingly outnumbered in terms of published research supporting their theories. To me, the balance of evidence is strongly in favour of human caused global warming. Anyone who trusts what the media says on science is silly, but that does not mean the media always get it entirely wrong. EDIT: Charles M's says scientists thought excess CO2 would cause cooling. This is a lie; aerosols cause massive cooling. We never saw major increases in aerosols, so the hypothesis was never tested. Also, the majority of papers in the 70's predicted warming. I am not aware of any papers claiming that this is the fastest warming ever. You only have to look at the Younger Dryas, which is included in the IPCC reports. Saying it has got hotter in every previous climate optimum is, however, 'creative' use of data (I would call it lying). has the last milankovic peak. Points 860-760 show warming over 3,200 years totaling about 8.6C. Or 0.02C per decade, compared with observed warming of 0.2C per decade recently. 'Second lie': I assume he means recorded history. According to the EPICA ice core data presented previously, the peak temperature in the past 600,000 years has been a few degrees hotter than today. Not 5C - I've no idea where you got these obscene numbers from. The idea that it's been warmer in the past 1,000 years is far from certain; there is significant evidence that medieval warm periods were regional and not strongly synchronous (ie they occurred at different times in different places). Various global/hemisphere palaeoclimate reconstructions support this. Lie 3: I would like to see more evidence for that. Since it is pretty certain that average global temperatures in the 2000s were higher than at any time in the 1900s.
