How to see the test report of tile sanitary ware

Into the building materials market, most products will provide a series of test reports and certificates. However, for ordinary consumers, want to read some of the quality indicators or terminology inside is not an easy thing. What's more, at present, there are some merchants in the market in order to make profit, will take a copy, alteration and other ways to use fake or expired test reports to muddle through, consumers simply can not identify. To this end, the Beijing Building Materials Institute recently held a press conference on building materials test report interpretation. 1. Whether the riding seal and the name of the inspection unit; 2. Whether the 'cal' chapter and 'cma' chapter, one cannot be missing, a higher level of 'cnal' national laboratory accreditation chapter, the above with the recognition of the national or provincial units above the number, you can go to the website of the relevant government agencies to check the authenticity of the report; 3. Report No. cover and core number is consistent; 4. Whether the report is in effect (generally) Whether the report is within the validity period (generally one year). At the same time, Beijing Building Materials Institute experts also explained how to read the test report. 1. Tiles: the following items in the test report should be complete, including: dimensional deviation, surface quality, water absorption, destructive strength, modulus of rupture, resistance to thermal shock, resistance to glaze cracking, frost resistance, abrasion resistance, resistance to contamination; 4. Architectural hardware (locks, water pipes, handles, etc.): sanitary ware hardware, plumbing products: the report should reflect the sample specifications, models and samples of the state (in good condition or have been used). Must indicate the testing standards on which the test is based. Mainly on the appearance of quality, thread appearance and quality, plating quality, flow, sealing strength, sealing strength on the strength of the valve body. 6. Sanitary ware and its fittings: tank fittings: instantaneous flow greater than 1.8l / s; must have anti-siphon device; sealing and strength to meet the relevant standard requirements.
