Into the building materials market, most products will provide a series of test reports and certifications. However, for ordinary consumers, it is not an easy task to read some quality indicators or technical terms. What's more, at present, there are some businesses on the market who, for the sake of profit, will use counterfeit or expired test reports to copy and alter their records, and consumers will not be able to discern. To this end, Beijing Building Materials Institute recently held a press conference to interpret the building materials inspection report. 1. Whether the riding stitch is the same as the name of the inspection unit; 2. Whether there are CAL chapters and CMA chapters are indispensable, and higher level ones must have CNAL national laboratory accreditation chapters.

Whether the report is valid (usually one year). At the same time, experts from the Beijing Building Materials Institute also explained how to read test reports. 1. Tiles: The following items in the test report should be complete, including: dimensional deviation, surface quality, water absorption, failure strength, modulus of rupture, thermal shock resistance, crack resistance, frost resistance, abrasion resistance, and resistance Pollution 2.

The test standard on which the test is based must be stated. Mainly for appearance quality, thread appearance and quality, plating quality, flow, seal strength, seal strength, body strength, etc.; 3, sanitary ware and accessories: water tank accessories: instantaneous flow rate greater than 1.8L / S; must have anti-siphon devices; sealing and strength to meet the relevant standards. Water spout: appearance without scratches, damage and other defects; sealing performance to meet the relevant standards; flow at 0.1MPA ≤ 0.15L / S, 0.3MPA ≥ 0.2L / S; life test to meet the relevant standards.
