China has achieved a new milestone in its manned space program, with the country's first international standard project being officially registered by the International Organization for Standardization (ISO). This represents China's first successful international standard in the field of manned spaceflight and a breakthrough in global space rule-making.

The standard is expected to provide a "Chinese solution" for the safety of manned space missions and further enhance China's international influence and voice in the field, according to the China Manned Space Agency (CMSA) on Tuesday.

According to the CMSA, the project — ISO/NP 14620-5 "Space Systems — Safety Requirements — Part 5: Manned Spacecraft" — was proposed by China's National Technical Committee on Manned Spaceflight Standardization.

Based on extensive research and by drawing on advanced international safety technologies and methodologies, the standard incorporates more than 30 years of safety experience from China's manned space program, the CMSA said.

It provides unified technical guidance and models for manned spacecraft safety applicable to all countries, setting out safety access conditions for participation in manned space activities.

Serving as the safety baseline and threshold for ensuring safety in  manned space missions and developing related systems and payloads, the standard is also expected to facilitate international cooperation on China's space station.
