如何檢查防爆證書嘅真偽

選擇防爆電氣設備時, 消費者通常傾向於擁有有效防爆證書嘅製造商或分銷商. 但, 作為消費者, 如何驗證呢啲紙嘅真實性?

目前, 該国擁有10多傢具有國家認可嘅防爆證書頒發資格嘅認證機構, yet no unified platform exists for their verification. The validity of certificates issued by each authority is only ascertainable through their respective designated websites. 答案係肯定嘅, one can also verify the certificate’s authenticity via phone with the respective issuing authority.

Should the certificate be authentic, its main parameters and expiration date will be displayed. 相反, fake certificates will yield no results in searches. It’s important to note that due to manual uploading by the issuing bodies, there might be a delay in reflecting the most recent certificates on their websites. 因此, direct telephonic consultation with the issuing authority might be necessary.
