What does ENF grade board refer to? Which boards can meet this standard?
The smell of newly purchased solid wood furniture is very strong. What methods can we use to remove its smell? Let me teach you several methods below. Opening doors and windows for ventilation is necessary, but to quickly remove the smell, you must also use the following methods: 1. Adsorption method (activated carbon) Adsorption is a solid surface phenomenon. It uses porous solid adsorbents to treat gaseous pollutants, so that one or several components, on the solid adsorbent surface, during the d
ENF grade is the new environmental protection standard for board enterprises issued on October 1st this year, commonly known as the board "new national standard". According to this standard, the formaldehyde-free level requirement is ≤0.025 mg/m³. Compared to the old national standard, although the difference is minimal, it imposes more stringent requirements on board production and processing enterprises. It also means that under the current standards, if enterprises want to meet the standard, they must further optimize and improve in various aspects such as raw material control, process technology, and quality inspection.
As a British high-end customization brand, ALLVS's Asian processing centers located in Guangzhou and Shanghai, China have fully launched ENF preparation, completed ENF upgrade for all product lines in December 2021, and ALLVS has completely phased out E0 and E1 environmental protection grade raw materials. Currently, the selected materials only include JapaneseF☆☆☆☆and the higher ENF grade.
ALLVSProducts that achieve the highest ENF standard have even stricter detection values than the American Carb naf zero-formaldehyde certification!
Note: Although the sampling methods of Japan and the United States are slightly different from China's national standard, for example, Japan does not allow edge banding while China allows it, but it is universally acknowledged in the industry that the national standard's numerical requirements are very low.
Previously, American Carb naf and Japanese F☆☆☆☆ were considered the highest formaldehyde release standards. In Carb naf, NAF stands for "No added Formaldehyde".
Because formaldehyde exists naturally everywhere, in trees and even in our bodies (see below), it is impossible to say zero formaldehyde (the "zero formaldehyde" claimed by merchants is all deceptive), so it can only be said that no additional formaldehyde is added during the production process.
