F★★★★是日本的“F★★★★认证，并得到国际认同、通行的一个环保认证体系；常用在建筑材料及室内装饰材料的产品中使用，是JIS（Japanese Industrial Standards日本工业规格）的工厂产品必须要标示的符号，是国际甲醛等级最高规格的标示符号。 2003年，日本按照法律实施所有木制建材类商品必须达到一定“★”数量才能使用。而F★★★★属于木制建材的最高等级，因此，F★★★★也是现行日本环保标准最高的健康等级，更被认为是国际上更为健康的标准。

国内标准：

新国标E1级是国内目前最高的环保等级，国标GB18580-2017要求甲醛释放量是0.124mg/m3，检测都是用1m3气候箱法。

欧盟标准：

欧盟的93/68/ECC建筑产品安全指令中做出了相关规定，分为E1、E2两级，在甲醛释放速度上E1级不超过0.12 mg/㎡h，E2级则在0.12 mg/㎡h以上，而在甲醛释放量上，则分别不超过1.5 mg/L、不超过5 mg/L。

日本标准：

日本F★★★★是由日本国土交通大臣规定的代表日本最高环保级别甲醛释放等级标准。通过F★★★★认证的产品甲醛释放速度在0.005mg/㎡h以下，甲醛释放限量平均值不超过0.3mg/L。可以看出，在所有标准中，日本F★★★★的标准是最高的，更被全球业内认为是甲醛趋零释放，也是世界公认的甲醛释放等级最环保表现！

日本法律规定：

F★★★★人造板在室内可以无限量使用，对人体健康基本无损害！

F★★★★ is Japan’s "F★★★★ certification, an environmental protection certification system recognized internationally; it is commonly used in building materials and interior decoration materials, and is JIS (Japanese Industrial Standards) ) Factory products must be marked with the highest standard of international formaldehyde. In 2003, Japan implemented the law in accordance with the law. All wooden building materials must reach a certain number of "★" before they can be used. F★★★★ The highest grade of wooden building materials, therefore, F★★★★ is also the highest health grade of the current Japanese environmental protection standards, and is considered to be a healthier standard in the world.

Domestic standards:

The new national standard E1 level is currently the highest environmental protection level in China. The national standard GB18580-2017 requires that the formaldehyde emission is 0.124mg/m3, and the detection is carried out by the 1m3 climate chamber method.

EU standards:

The European Union’s 93/68/ECC Construction Product Safety Directive has made relevant regulations, which are divided into two levels, E1 and E2. In terms of the formaldehyde release rate, E1 level does not exceed 0.12 mg/㎡h, and E2 level is 0.12 mg/㎡h. Above, and in terms of formaldehyde emission, it does not exceed 1.5 mg/L and 5 mg/L respectively.

Japanese standard:

Japan F★★★★ is a formaldehyde emission standard set by the Minister of Land, Infrastructure, Transport and Tourism, which represents the highest environmental protection level in Japan. The formaldehyde emission rate of F★★★★ certified products is below 0.005mg/㎡h, and the average formaldehyde emission limit does not exceed 0.3mg/L. It can be seen that among all the standards, the Japanese F★★★★ standard is the highest, and it is considered by the global industry to be zero formaldehyde emission, and it is also the world's most recognized formaldehyde emission level for the most environmentally friendly performance!

Japanese law stipulates:

F★★★★Man-made panels can be used in an unlimited amount indoors, basically without harm to human health!

F★★★★的五个特点

F★★★★特点一：

F★★★★标准认证甲醛的释放量≤0.3mg/L，F★★★★标准是同行公认的更严格的甲醛释放量标准。

业内通常认为：用脲醛胶只能造出F★的板材，用改性的脲醛胶只能造出F★★的板材，F★★★★的板材则只能采用无醛胶制造。脲醛胶因其成本低廉仍为各国（包括发达国家）人造板工业的主要胶种，但其缺点就在于存在甲醛释放问题。无醛胶制造板材有两条途径，一是采用生物胶粘剂，但生物胶制作的板材存在胶合强度不高、耐水和耐热性能不好的缺点；二是采用异氰酸酯胶，但它最大的缺点是成本太高。

F★★★★特点二：

F★★★★标准是认证体系而非送检标准。

F★★★★不仅仅是一系列环保指标,还有一整套完整的测量方法要求,更有对产品供应链的严苛要求,这是和国内检测方法完全不同的认证体系。

行业人士都知道,在中国的检测方法是：人造板企业、压板企业或制造加工企业及产品销售商将人造板产品送至中国质量监督局(含省市级\地级), 中国质量监督局根据国家标准对送检的样本进行检测,检测报告仅对送检样本负责（很多企业根本不是送检自我产品）。所以大家仔细看中国检测报告会发现在检测结论一栏有以下文字:“依据WB/T1024************，对所送样品进行检测，所检项目符合标准要求”这是中国的检测程序和制度。

但是F★★★★标准并非如此，是由日本F★★★★指定机构派驻人员到达生产工厂，对工厂的整个生产体系进行评估检测，涉及所有生产的每个环节，从原材料，到生产工艺，到成品每个环节都必须符合F★★★★标准，确保该工厂整个体系上达到F★★★★，并对该工厂颁发认证证书，而且会每年派员驻场检测4次以上。

F★★★★特点三：

F★★★★的检测方法和中国的完全不同，对具体环保指标的检测方法也有很大的不同，日本F★★★★标准检测面积为1800 C㎡，不允许封边，水浴温度为65±2度时检测, 中国检测面积为180 C㎡，四周铝箔包裹，只留表面露出，室温检测即可。可以看到，在具体的检测方法上，日本F★★★★的检测面积是中国的10倍，检测温度是中国的3倍，检测方位是中国的4倍，这使得最终的检测结果仅仅是数据上的对比已经失去了可比性。（国标GB18580-2017采用的是乙酰丙酮分光光度法，这个方法虽然操作简便、性能稳定、误差小，但是对甲醛的灵敏度较低，最低的检出浓度为0.02mg/(㎡h) 。而日本F☆☆☆☆采用的高效液相色谱法则对甲醛的灵敏度很高，检测极限很低，能达到0.0011 mg/(㎡h)！换句话说，国标检测低于0.02mg/(㎡h)就检测不出来了，但是F★★★★的检测更能检出更小剂量的甲醛释放！）

F★★★★特点四：

没有日本指定机构认证的F★★★★根本就不是真正的F★★★★；在中国国内获得认证的企业不到10家。

F★★★★只有认证证书，而没有检测报告，因为F★★★★是一个认证体系，所以只有日本JAS颁发的认证证书（对F★★★★标准达标的体系认证）

F★★★★特点五：

家庭装载量多少会直接影响甲醛释放量

所谓家庭装载量就是家庭中使用了多少人造板板材（如地板、装饰面板、木工板等）或含有甲醛的纺织品及家具。

以地板为例：一户150平米的住房，地板铺装面积约为100平米,简单假设,单位面积的甲醛含量为0.3mg的地板（日本F★★★★）和甲醛含量为0.5毫克（E0级）的地板，二者相差仅仅是0.2毫克，但是整体铺装后的甲醛含量相差是0.2mg的100倍，也就是20mg，这就是个惊人的差异了！

所以日本法律规定：

只有达到F★★★★标准的产品，室内才可以无限量使用；E0级的产品，限2倍地面面积使用（说明：限2倍地面面积，指所有材料的摊开面积，合计不得大于地面面积的2倍。）

2004年6月5日，世界卫生组织发布第153号公告，宣布甲醛为一级致癌物。甲醛为较高毒性的物质，在我国有毒化学品优先控制名单上，甲醛高居第二位。中国疾病预防控制中心的调查结果显示：我国居民家庭装修的甲醛超标率高达60%。

甲醛的主要危害表现为对皮肤粘膜的刺激作用,甲醛在室内达到一定浓度时，人就有不适感。大于0.08m³的甲醛浓度可引起眼红、眼痒、咽喉不适或疼痛、声音嘶哑、喷嚏、胸闷、气喘、皮炎等。新装修的房间甲醛含量较高，是众多疾病的主要诱因。

生活中对人体造成伤害的甲醛，可以说无处不在。涉及的物品包括家具、木地板；童装、免烫衬衫；快餐面、米粉；水泡鱿鱼 、海参、牛百叶、虾仁；甚至汽车。不难看出，衣、食、住、行——我们生活最重要的四件事，甲醛竟然全部染指了，无处不在的甲醛让人忧心忡忡。

选择F★★★★标准的产品，就选择了健康！

Five characteristics of F★★★★

F★★★★Feature 1:

F★★★★The standard certified formaldehyde emission ≤0.3mg/L, the F★★★★ standard is a more stringent formaldehyde emission standard recognized by the industry.

The industry generally believes that only F★ boards can be made with urea-formaldehyde glue, F★★ boards can only be made with modified urea-formaldehyde glue, and F★★★★ boards can only be made with no-formaldehyde glue. Urea-formaldehyde glue is still the main glue type in the wood-based panel industry in various countries (including developed countries) due to its low cost, but its disadvantage lies in the problem of formaldehyde release. There are two ways to make boards with formaldehyde-free glue. One is to use bio-adhesive, but the board made of bio-glue has the disadvantages of low bonding strength, poor water resistance and heat resistance; the other is to use isocyanate glue, but its biggest disadvantage is the cost is too high.

F★★★★Feature 2:

F★★★★The standard is a certification system rather than a standard for inspection.

F★★★★ is not only a series of environmental protection indicators, but also a complete set of measurement method requirements, and more stringent requirements for the product supply chain. This is a certification system that is completely different from domestic testing methods.

People in the industry know that the testing method in China is: wood-based panel companies, press-board companies or manufacturing and processing companies and product sellers send wood-based panel products to the China Quality Supervision Bureau (including provincial and municipal levels), China Quality Supervision Bureau The samples submitted for inspection are tested according to national standards, and the test report is only responsible for the samples submitted for inspection (many companies do not submit their products for inspection at all). Therefore, if you look at the China test report carefully, you will find the following text in the test conclusion column: "According to WB/T1024************, the sent samples are tested, and the tested items meet the standard requirements." This is China's testing procedures and systems.

However, the F★★★★ standard is not the case. It is the Japanese F★★★★ designated agency that sends personnel to the production plant to assess and test the entire production system of the plant, involving all production links, from raw materials to production processes , Every link to the finished product must meet the F★★★★ standard to ensure that the entire system of the factory reaches F★★★★, and the factory will be issued a certification certificate, and staff will be stationed for inspections more than 4 times a year.

F★★★★Feature three:

The detection method of F★★★★ is completely different from that of China, and the detection method for specific environmental indicators is also very different. The standard test area of F★★★★ in Japan is 1800 C㎡, edge sealing is not allowed, and the water bath temperature is 65 When testing at ±2 degrees, the testing area in China is 180 C㎡, surrounded by aluminum foil, leaving only the surface exposed, and testing at room temperature is sufficient. It can be seen that in terms of specific detection methods, the detection area of Japan F★★★★ is 10 times that of China, the detection temperature is 3 times that of China, and the detection orientation is 4 times that of China. This makes the final detection result only The comparison of data has lost comparability. (The national standard GB18580-2017 uses acetylacetone spectrophotometry. Although this method is simple to operate, stable in performance, and small in error, it has low sensitivity to formaldehyde, and the lowest detection concentration is 0.02mg/(㎡h). Japan F☆☆☆☆ The high performance liquid chromatography method adopted is very sensitive to formaldehyde, and the detection limit is very low, reaching 0.0011 mg/(㎡h)! In other words, the national standard detection is less than 0.02mg/(㎡h). It can't be detected, but the F★★★★ test can detect even smaller doses of formaldehyde release!)

F★★★★Four Features:

F★★★★ that is not certified by a Japanese designated agency is not a real F★★★★; less than 10 companies have been certified in China.

F★★★★ only has a certification certificate, but no test report. Because F★★★★ is a certification system, there is only a certification issued by JAS (for F★★★★ standard system certification)

F★★★★Five Features:

The amount of household loading will directly affect the amount of formaldehyde released

The so-called household load is the number of wood-based panels (such as floors, decorative panels, wood panels, etc.) or textiles and furniture containing formaldehyde used in the family.

Take the floor as an example: a house of 150 square meters, the floor area is about 100 square meters, simple assumption, the formaldehyde content per unit area of the floor is 0.3mg (Japanese F★★★★) and the formaldehyde content is 0.5 mg (E0 Grade), the difference between the two is only 0.2 mg, but the difference in formaldehyde content after the overall paving is 100 times that of 0.2 mg, which is 20 mg, which is an amazing difference!

Therefore, Japanese law stipulates:

Only products that meet the F★★★★ standard can be used in an unlimited amount indoors; E0 products are limited to 2 times the floor area (Note: 2 times the floor area is limited to the spread area of all materials, and the total must not be larger than the floor. 2 times the area.)

On June 5, 2004, the World Health Organization issued Announcement No. 153, declaring formaldehyde as a primary carcinogen. Formaldehyde is a highly toxic substance, and formaldehyde ranks second in the priority list of toxic chemicals in my country. The survey results of the Chinese Center for Disease Control and Prevention show that the formaldehyde in the home decoration of Chinese residents exceeds the standard rate as high as 60%.

The main hazard of formaldehyde is the irritation to the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Formaldehyde concentrations greater than 0.08m³ can cause red eyes, itchy eyes, throat discomfort or pain, hoarse voice, sneezing, chest tightness, asthma, dermatitis, etc. The newly renovated rooms contain high formaldehyde content, which is the main cause of many diseases.

It can be said that formaldehyde, which causes harm to the human body in life, is everywhere. The items involved include furniture, wooden floors; children's clothing, non-iron shirts; fast food noodles, rice noodles; blistered squid, sea cucumbers, beef shutters, shrimps; even cars. It is not difficult to see that clothing, food, housing and transportation-the four most important things in our lives, formaldehyde has all been involved. The ubiquitous formaldehyde makes people worry.
