Tianjin Economic and Technological Development Zone Enterprise Service Bureau (Tianjin Economic and Technological Development Zone Park Law Enforcement Bureau) purchases laboratory equipment for four schools including Bincheng School of Yaohua Middle School in Tianjin in 2025 (Project Number: TJBH-2025-A-0005) Correction Announcement No. 1 [Information Time: April 15, 2025] Entrusted by Tianjin Economic and Technological Development Zone Enterprise Service Bureau (Tianjin Economic and Technological Development Zone Park Law Enforcement Bureau), the Tianjin Binhai New Area Government Procurement Center will implement government procurement for the laboratory equipment project for four schools including Bincheng School of Yaohua Middle School in Tianjin in 2025 through open bidding. Some of the project contents are now corrected. 1、 The main content of the original announcement is as follows: (1) Procurement project name: Tianjin Economic and Technological Development Zone Enterprise Service Bureau (Tianjin Economic and Technological Development Zone Park Law Enforcement Bureau) Procurement of laboratory equipment project for four schools including Bincheng School of Yaohua Middle School in Tianjin in 2025. (2) Procurement project number: TJBH-2025-A-0005. (3) First announcement date: April 14, 2025. (2) Correction items and content: Change the content of item (3) in the evaluation of the objective fourth material testing report. The corrected content is as follows: (3) Provide scanned copies of the testing report issued by a third-party testing institution for the solid core physical and chemical board of the table. The above testing report can prove that the above materials meet the following parameter requirements: 0.25 points for each item certified. Up to 2 points A Chemical properties: tested using at least 126 chemical reagents such as sulfuric acid (98%), nitric acid (65%), sodium hydroxide (40%), acetonitrile, carbon tetrachloride, turpentine, iodine, etc. B. Formaldehyde content testing: Tested by authoritative institutions such as the National Chemical Building Materials Testing Center or SGS with reference to the latest standard (GB/T18580-2017), the test result shows that the formaldehyde emission is ≤ 0.025mg/M3, meeting the technical limit requirement of E1 level ≤ 0.124mg/M3. C. Physical performance testing: Conduct no less than 18 physical performance tests based on relevant standards and methods through institutions such as the National Chemical Building Materials Testing Center. The test results are: moisture content: ≤ 1.1; Surface resistance to cold and hot cycles (80 ℃): no cracks, no bubbles, discoloration, wrinkling; Paint film hardness ≥ 8H; Paint film adhesion: The cutting edge is completely smooth without any peeling off; The surface resistance to dry heat, surface resistance to moisture and heat, surface resistance to cigarette burns, and resistance to boiling water are all at level 5 without any changes; Water absorption ≤ 0.1%; The surface wear resistance test result shall not be less than 568r; High temperature resistance: no cracks on the surface; Bending strength ≥ 120MPa; Impact resistance: The indentation diameter is ≤ 6.0mm, and the surface is undamaged; Color fastness to light ≥ level 4; Surface wear resistance (wear value) ≤ 49mg/100r; Surface crack resistance: Level 5, no cracks observed on the surface with a 6x magnifying glass; Dimensional stability shall not exceed 0.55% in both longitudinal and transverse directions; The density reaches 1.4g/cm3 or above D.
