| 1 | Electric motors | Pumps, fans, conveyors, compressors, and other driven equipment. | Rated power, voltage, frequency, speed, duty, enclosure protection, mounting, and efficiency. | Match the motor to the load and local power supply; verify dimensions, operating conditions, and the efficiency class required for the market. | Datasheet, wiring diagram, test records, and applicable conformity documents. IEC 60034 is a relevant international motor standards series. |
| 2 | Centrifugal pumps | Water supply, circulation, irrigation, process transfer, and building services. | Flow rate, total head, liquid temperature, materials, seal type, connection size, and motor requirements. | Compare the duty point with the pump curve; check liquid compatibility, suction conditions, seal suitability, and expected maintenance access. | Performance curve, installation and maintenance instructions, materials list, and test report. |
| 3 | Industrial valves | Flow isolation, regulation, and control in piping systems. | Valve type, nominal size, pressure rating, end connection, body and trim materials, temperature range, and actuation. | Confirm compatibility with the process fluid and system design; specify the required leakage class, orientation, and operating method. | Dimensional drawing, material and pressure-test records, operating instructions, and applicable product approvals. |
| 4 | Rolling bearings | Rotating shafts in motors, gearboxes, wheels, fans, and machinery. | Bearing type, bore and outside diameter, width, load direction, speed, clearance, and lubrication requirements. | Verify the full designation and boundary dimensions; assess load, speed, temperature, sealing, and installation conditions. | Dimensional and tolerance information, material details where specified, lubrication guidance, and traceability records. |
| 5 | Power cables | Power distribution and equipment connections in buildings, infrastructure, and industry. | Conductor material and area, voltage rating, insulation, number of cores, temperature rating, installation environment, and fire performance. | Check the destination-market requirements, installation method, electrical load, environmental exposure, and cable marking before ordering. | Construction datasheet, applicable test reports, conductor details, and required regional conformity documentation. |
| 6 | LED luminaires | Indoor, outdoor, warehouse, office, and industrial lighting. | Light output, efficacy, color temperature, color rendering, beam distribution, ingress protection, dimming, and rated life conditions. | Assess lighting needs for the space; distinguish luminaire output from LED-chip claims and check thermal management and driver compatibility. | Photometric data, electrical safety and EMC test documents, installation instructions, and warranty terms. IEC 60598 is a relevant luminaire standards series. |
| 7 | Pressure and temperature sensors | Process monitoring, equipment protection, automation, and control systems. | Measurement range, accuracy, output signal, process connection, response time, wetted materials, and operating environment. | Check compatibility with the medium and control system; verify calibration needs, measurement range, and environmental protection. | Datasheet, wiring diagram, calibration information, operating instructions, and material declarations where required. |
| 8 | Industrial fasteners | Structural assemblies, machinery, maintenance, and general construction. | Fastener type, dimensions, thread, material, property class, coating, and corrosion environment. | Confirm the specified standard and grade, ensure the coating suits the environment, and check whether required mechanical test results are available. | Dimensional specification, material or mechanical-property test records, coating details, and batch traceability. |
| 9 | Personal protective equipment | Workplace protection for tasks involving impact, chemical, electrical, thermal, or other hazards. | Protection type, applicable hazard level, size range, materials, fit, compatibility with other equipment, and service-life limits. | Select equipment through a task-specific risk assessment; check destination-market rules, fit, user instructions, and replacement guidance. | Applicable conformity documents, user instructions, care guidance, and test information for the specific PPE type. |
| 10 | Packaging materials | Product protection, storage, transport, and retail or industrial distribution. | Material, dimensions, load or stacking requirements, barrier properties, closure method, and transport conditions. | Test packaging with the actual product and shipping route; consider moisture, impact, handling, recyclability, and destination-market packaging rules. | Material specifications, packaging test results where needed, handling instructions, and relevant environmental or compliance information. |
