Two core criteria shall be checked: whether the product itself complies with national standards, and whether systematic acceptance tests are carried out after installation. The prevailing domestic national standard is GB/T 36340-2018 General Specification for Anti-Static Raised Access Floor. Products manufactured by formal manufacturers shall be accompanied by test reports complying with this standard. During procurement, you may ask suppliers to provide test reports issued by authoritative institutions, with focus on core indicators such as surface resistance and load-bearing capacity.

Post-installation acceptance is equally vital. Key indicators to be tested include: the system resistance of the floor shall be maintained between 10⁶Ω and 10⁹Ω to guarantee effective static dissipation; the grounding resistance shall generally be no more than 4Ω; additionally, the flatness of the floor surface shall be inspected, and no abnormal noise or wobbling shall occur while walking on the floor.

If any indicator fails to meet the standard during acceptance, require the contractor to complete rectification before signing off. Do not settle for "close enough". As critical infrastructure, substandard anti-static floors will lead to huge costs when equipment malfunctions occur later. Qualified construction teams will conduct item-by-item testing with professional instruments during acceptance and issue official acceptance reports, which serve as important evidence to judge product qualification.
