Popularization of knowledge on verification certificates of 【Electronic tensile testing machine】

There are two types of verification certificates for electronic tensile testing machines, one is issued by the manufacturer, and the other is issued by the Quality Supervision Bureau. Although the contents of the two are similar, the representative meanings are very different. Many users often have little understanding of these two certificates, or directly think that they are one. For this point, I will introduce it to you separately.

1. Quality inspection certificate provided by the manufacturer

AsElectronic tensile testing machineThe manufacturer must have corresponding quality inspection departments, which are mainly engaged in the verification of the performance and supporting products of the equipment before shipment. After the inspection introduction, an inspection certificate will be issued, which mainly includes the verification unit, production unit, product name, equipment specifications, factory number and product verification conclusion, validity period, and signed by the verification personnel. This verification certificate is only issued by the manufacturer unilaterally. It is the manufacturer's verification of its own products, which is equivalent to the product's certificate of conformity and the date of equipment warranty. It is effective for manufacturers and users, but it may not necessarily be effective for quality inspection agencies, etc.

2. Inspection certificate provided by the Quality Inspection Bureau

This certificate is a quality inspection institution to verify a certain indicator or all indicators of equipment produced by a test machine manufacturer. The certification certificate mainly includes the inspection unit, the inspection unit, the manufacturer, the equipment name, specification, the factory number, the verification conclusion date and the front of the relevant personnel, and is stamped with a special seal of the Quality Supervision Bureau. The inspection of the Quality Supervision Bureau has national effectiveness. For example, the Quality Supervision Bureau that passes the inspection by the manufacturer may not pass the inspection, but otherwise, it will be qualified. Moreover, manufacturers of test machines also need a measurement license issued by the Quality Supervision Bureau to produce a certain type of production.Electronic tensile testing machineQualifications.

Kind tips:

1. Under normal circumstances, the manufacturer will not provide the verification certificate issued by the Quality Inspection Bureau. Unless the user has special needs, the manufacturer can help, but the user needs additional fees.

2. The date and time for the common verification certificate is the date of free maintenance by the manufacturer, which is generally one or two years. This is determined by the manufacturer, but the period for the verification certificate presented by the Quality Supervision Bureau is based on three years and is fixed.
