Standards Development

Scope

Current international practices for liquid launch vehicle testing at launch sites exhibit significant divergence in test items, content, acceptance criteria, and safety boundaries. Presently, no dedicated International Standard exists to define the minimum mandatory requirements for this specific phase. This fragmentation creates technical barriers to cross-border commercial launch cooperation and elevates the risk of accidents resulting from insufficient testing.

This International Standard establishes ageneric, effective, economical, and safe framework of minimum requirements for liquid launch vehicle testing activities conducted at the launch site. The scope is strictly limited to defining the test items and status confirmation principles for functional parts, subsystems, and the overall system following transportation and final assembly. It doesnot prescribe specific test methods, procedures, or instrumentation. By unifying the baseline for launch site testing, this document fills the current regulatory gap, supports the development of low-cost rapid launch capabilities and reusable launch vehicles, mitigates launch failure risks, and promotes the healthy growth of global commercial space activities.

Purpose

This standard addresses five critical gaps in the current aerospace ecosystem: Addressing Regulatory Fragmentation There is currently no unified international baseline for launch site testing. Significant discrepancies exist among national safety regulations and corporate test protocols, impeding crossborder launches (e.g., foreign-built launchers utilizing domestic launch sites). This standard establishes common criteria to streamline international cooperation and regulatory approval processes. Balancing Innovation with Risk Control Market demand for low-cost, rapid launch capabilities has led some commercial entities to reduce necessary testing. In the absence of a recognized minimum standard, the risk of accidents—including launch failure, casualties, facility damage, and environmental pollution—increases significantly. This standard provides flexibility by not prescribing specific test methods, while ensuring essential tests are not omitted for cost reduction, thereby preventing latent hazards from reaching the flight phase. Supporting Reusable Launch Vehicle (RLV) Development To address the re-test requirements for recovered launch vehicles prior to reuse, this standard establishes a unified verification baseline to ensure recovered hardware meets stringent safety requirements for subsequent flights. Enhancing Launch Success and Safety Assurance Through standardized test items and status confirmation mechanisms, this standard mitigates risks arising from inadequate testing, missing processes, or inconsistent verification—specifically reducing the likelihood of launch failure, personal injury, vehicle destruction, and environmental contamination. Optimizing Launch Site Resource Utilization With increasing launch cadences, minimizing launch site occupancy time is critical. By clearly defining "what must be tested" without constraining "how to test," this standard simplifies pre-launch workflows, reduces unnecessary delays, and improves overall launch site throughput efficiency.
