What does the symbol on the bottom of the stainless steel water cup mean?Is it required by the national standard? (two)

The editor mentioned a convenient and fast detection method in the previous article, and I will talk about it again here.If you have a Bluetooth headset with you, use the magnet on the Bluetooth headset to absorb the cup.If you can suck it up, it must be not 304 stainless steel or 316 stainless steel. Specifically, why please refer to the previous article of the editor.

The stainless steel vacuum flask is usually composed of an outer shell, an inner liner, and a bottom of the cup.The editor has been asked by friends countless times to identify whether the newly purchased water cup is "the wrong product".After inspection by the editor, it is found that most of the water cups are really "not the right product", and the bottom of the liner of some water cups is marked with 316, but after testing, it is found that except for the one with 316 on the liner, other parts of the whole cup body The materials are actually 201.

Therefore, the editor advises you not to buy water cups only with the logo on the bottom of the water cup. It does not mean that a water cup without a stamping icon at the bottom is a substandard water cup.The water cup factory where the editor is located is a perennial export OEM, so among these tens of thousands of water cups, there are water cups with digital icons and water cups without digital icons.

Here, the editor would like to declare to everyone again that the editor did not discredit the entire drinking glass industry, after all, the editor is also one of them.The materials used by most of the drinking glass factories on the market are worthy of belief. After all, there are still the majority of conscience companies, and only a few ignorant drinking glass factories will do this.The editor cannot judge the quality of the water cup by the market retail price of the water cup, and can only share and teach you some simple test methods through article by article.
