檢查井蓋承載能力試驗以1kN/s～5kN/s的速率加荷至井蓋規定的試驗荷載值，試驗荷載保持30s，檢查井蓋不出現裂縫爲合格。
檢查井蓋殘留變形檢測，試驗前用千分表記錄井蓋幾何中心位置初始值，測量精度0.001mm。以1kN/s～5kN/s的速率施加荷載，達到規定的井蓋試驗荷載，保持30s然後卸載。此過程重複5次，待第5次卸載後30s時記錄幾何中心的最終變形值。初始值和第5次卸載後最終值之差爲井蓋殘留變形值。
檢查井蓋承載能力試驗機采用上加載型式，井蓋承載力加載設備應當能提供井蓋試驗荷載1.2倍以上的加載能力。HRJ井蓋承載能力試驗機由加載設備、剛性墊塊、橡膠墊片等組成，采用上加載型式，滿足A15，B125，C250，D400，E600，F900井蓋承載能力試驗。符合EN 124-2015，AS NZS 3396-2019，EN 1433，
JIS A5337，ASTM A48/A48M，ASTM 888-2015，ASTM A536，BS 2789，NF A32，CNS 10841。1250kN電液伺服井蓋壓力試驗機，用于英國標准協會（BSI）、歐洲標准化委員會（CEN）標准制修訂和井蓋試驗論證，對出口歐洲的中國井蓋制品進行仲裁檢測。
