E1 is a rating of the amount of formaldehyde present. The measurements are obtained by using the Perforator Test Method. Here are the ratings:
E0 <= .5 mg of formaldehyde per 100 g of dry board.
E1 > .5 mg and <= 9 mg of formaldehyde per 100 g of dry board.
E2 > 9 mg and <= 30mg of formaldehyde per 100 g of dry board.
E3 > 30 mg per 100 g of formaldehyde per 100 g of dry board.
E1 and E2 glues are two types of protein-based adhesives commonly used in woodworking. E1 glue is a formaldehyde-based adhesive that emits low levels of formaldehyde, while E2 glue emits even lower levels. E2 glue is considered safer for indoor use due to its lower formaldehyde content.
'de la colle' means (some) glue in French.
The key difference between the E1CB and E1 mechanisms in organic chemistry is the presence of a base in the E1CB mechanism, which facilitates the elimination reaction, while the E1 mechanism involves a unimolecular elimination without the need for a base. Additionally, the E1CB mechanism typically occurs in molecules with acidic hydrogen atoms, while the E1 mechanism is more common in molecules with stable carbocations.
Heat favors E1 reactions because it provides the energy needed to break the bond between the leaving group and the carbon atom, allowing for the formation of a carbocation intermediate. This intermediate is more stable at higher temperatures, promoting the E1 reaction pathway over other competing reactions.
The potential risks of using e1 solvents in industrial processes include health hazards from exposure to toxic chemicals, environmental pollution from improper disposal, and fire hazards due to their flammable nature. It is important to handle and store e1 solvents safely to minimize these risks.

E1s mean more E1 channel,for example,2E1,4E1,8E1,16e1 etc
Read the legend on the electric schematic, it will tell you what E1 is denoted as.

E1 on an infrared heater typically indicates an error related to the temperature sensor. It could mean that the sensor is malfunctioning or that there is an issue with the wiring. Check the sensor and connections to troubleshoot the problem.
There are 63 e1's in sdh STM-1 = 63 x E1; STM-4 = 63 x 4 E1; STM-16 = 63 x 16 E1; STM-64 = 63 x 64 E1.
Oh, what a happy little question! Playing the Super Mario notes on the xylophone can bring so much joy and creativity to your day. Just remember to start with the iconic melody and play around with the different notes until you find the perfect harmony that makes you smile. Happy xylophone playing, my friend!

It means that the test strip is damaged.
It means that the internet wont have an answer and you will waste alot of time trying to research the jewelry with an E1 stamp and not find sh*t. Then a reputable jeweler will probably rob you blind for it.
(E1 - E2)/E1 where E1 is the original expense and E2 is the new, lower expense.
