At present, the state has not yet officially issued a national standard on the E0 level. At present, the so-called E0 standard is mostly established within the industry. Brand shop: plate E0 means: less than or equal to 0.5 mg/L formaldehyde emission E1 means: formaldehyde emission amount less than or equal to 9.0mg/100g E2 means: formaldehyde release amount less than or equal to 30.0 mg/100g Formaldehyde is a colorless, harmful gas that can cause cancer of the nose, mouth, throat, skin, and digestive tract. The formaldehyde in the house is mainly derived from various types of wood, furniture, paint, and other decorative materials. According to the national mandatory standards, after closing doors and windows for one hour, the amount of formaldehyde released per cubic meter of indoor air should not exceed 0.08 milligrams; if it reaches 0.1 to 2.0 milligrams, 50% of normal people can smell bad; reaching 2.0-5.0 milligrams Eyes and trachea will be strongly stimulated.

JIS" Stands for Japanese Industrial Standard and are published by the Japanese Standards Association (JSA) which is the equivalent of ANSI in the United States. They are created and updated by the Committee of the Japanese Industrial Standards (JISC). Like JSA to ANSI, the JISC is similar to the American Society of Mechanical Engineers (ASME).
Japan Industrial Standard is yet another option for metric sizes. Provided in JIS5K, JIS10K, JIS15K, and JISK20K pressure classes, we can offer Slip On, Blind, and Weld Neck varieties in Raised Face or Flat Face configurations. These are typically made of 316/L or A105, but as usual, all alloys are available!
Much like DIN / metric flanges, the JIS Flange specification offers a slightly wider variety of slip weld configurations for the purposes of space limitations and suitability for existing pipeline equipment. For instance, a customer can request a slip on with or without a hub as standard, or even a ring type flange, and all of this within the same B2220 specification.
JIS flanges are commonly found in exported pressure equipment and pipe assemblies from Japan. Many large ships and sea vessels which travel through international waters and service the Pacific rim will utilize equipment made to this standard, as parts and servicing for this specification are widely available.
