The MDA (Méthode D’Analyse) named in this document are issued from the ISO Standards.
表中所提及的 MDA (Méthode D’Analyse) 是由 ISO 颁布的标准。 The values mentioned in this Technical Data Sheet are issued from test bars realized on specific equipment, in conformity with normalized standards. Although we estimate that these information are exact, it is important to know that under other conditions with another equipment than our, the results can be appreciably different.
Therefore we are not responsible when those information are not interpreted as they should be.
产品规格中所列的各项数据是由特别的仪器遵照标准化测试所得到的。 尽管我们认为这些信息是准确的， 但是如果在其它的情况下由其它的仪器所测得的数据可能有所不同， 所以， 客户应该自行确认产品可否被采用。
