| Generator-set performance | ISO 8528 series | Defines requirements and performance classifications for reciprocating internal-combustion engine-driven alternating-current generating sets, including ratings, tests, and operating characteristics. | Recommended for most commercial and industrial gas generator projects. | Rated-power sheet, factory test report, load-test results, voltage and frequency data, and the declared performance class. |
| Electrical-machine safety | IEC 60034 series | Covers rotating electrical machines, including generator ratings, temperature rise, insulation, efficiency-related information, and operating conditions. | Relevant when the alternator and electrical performance must meet international engineering specifications. | Alternator datasheet, insulation-class information, temperature-rise test data, efficiency data, and routine-test records. |
| Enclosure protection | IEC 60529 IP Code | Classifies protection provided by enclosures against solid objects and water ingress, such as IP23 or IP54. | Applies when the installation environment requires a specified enclosure protection level. | Declared IP rating, enclosure drawings, test report, and confirmation that the rating applies to the complete assembled unit. |
| Quality management | ISO 9001 | Demonstrates that the organization operates a quality-management system covering processes such as design, purchasing, production, inspection, and corrective action. | Useful for supplier qualification, especially for repeat orders, project contracts, and critical-power applications. | Valid certificate, certificate scope, issuing certification body, expiry date, and site address covered by the certificate. |
| Environmental management | ISO 14001 | Addresses an organization’s environmental-management processes, including environmental aspects, compliance obligations, and continual improvement. | Often requested in public procurement, infrastructure projects, and supply chains with environmental requirements. | Valid certificate and scope; this standard does not by itself certify engine emissions or product environmental performance. |
| Occupational health and safety | ISO 45001 | Provides a framework for managing occupational health and safety risks within the organization. | Commonly evaluated during vendor audits and large construction or energy tenders. | Valid certificate, certification scope, covered locations, and audit status. |
| European Union market access | CE marking and applicable EU legislation | Confirms the manufacturer has completed the conformity-assessment process for legislation applicable to the finished product, which may include machinery, electromagnetic compatibility, low-voltage, pressure, or noise requirements depending on the design. | Required when the complete generator set is placed on the EU market and falls within applicable harmonized legislation. | EU Declaration of Conformity, technical file or supporting records, risk assessment, user instructions, and product marking. CE is not a standalone quality certificate. |
| United Kingdom market access | UKCA or accepted CE route | Market-access marking and conformity documentation depend on the product category, destination within the UK, and current UK legislation. | Required for products supplied to Great Britain where the applicable UK conformity route requires it; Northern Ireland rules can differ. | Applicable declaration of conformity, technical documentation, labeling, and confirmation of the current route accepted for the product category. |
| Engine emissions | Destination-market emissions legislation | Controls pollutants such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Requirements differ according to engine type, power, fuel, application, and whether the unit is mobile or stationary. | Mandatory where the destination country or project imposes engine-emission limits or permitting conditions. | Engine model and serial data, emissions certificate or approval, test report, exhaust-system details, and installation-specific permit information. |
| Electromagnetic compatibility | Applicable EMC requirements and IEC 61000 series | Addresses electromagnetic emissions and immunity so that the generator and connected equipment operate reliably without unacceptable interference. | Important for installations with control systems, telecommunications equipment, hospitals, data centers, or sensitive electronics. | EMC test report, test configuration, control-panel information, cable and grounding requirements, and declaration of conformity where required. |
| Fuel-system and site safety | Local gas, pressure, fire, and electrical installation codes | Covers gas trains, regulators, ventilation, combustion air, exhaust routing, emergency shutdown, earthing, clearances, and fire protection. | Applies according to the installation country, gas type, building classification, and authority requirements. | Gas-train schematic, pressure and flow requirements, ventilation calculations, installation manual, wiring diagrams, and authority approvals where applicable. |
| Commercial export documentation | Commercial invoice and packing list | Provides customs and logistics information, including product description, quantities, values, packages, dimensions, weights, and trade terms. | Required for normal international shipments and customs valuation. | Ensure descriptions, quantities, weights, currency, consignee, country of origin, and agreed Incoterms are consistent across documents. |
| Transport and origin documents | Bill of lading or air waybill; certificate of origin | Proves shipment details and supports customs clearance, preferential-tariff claims, or destination-country origin requirements. | Required or requested according to the transport mode, customs regime, letter of credit, and importing country. | Check consignee, notify party, package count, marks, gross weight, port details, and origin information before shipment. |
| Customs classification | HS code and import requirements | The Harmonized System code supports tariff classification, duty assessment, statistical reporting, and import-control checks. | Required for customs entry; the final national tariff subheading may differ by destination country and configuration. | Confirm the code with the importer or customs broker; provide accurate fuel type, output, engine details, and complete-set description. |
| Technical handover | Operation, maintenance, and spare-parts documentation | Enables safe installation, commissioning, operation, preventive maintenance, troubleshooting, and regulatory inspection. | Required for responsible commissioning and should be supplied in the buyer’s agreed language before or with delivery. | Installation manual, wiring diagrams, P&ID or gas schematic, maintenance schedule, recommended spare-parts list, warranty terms, and commissioning checklist. |
