Aerospace series. Space systems. Fluid characteristics, sampling and test methods - Helium Ingestion-build-89079 What is BS 3166 -1 Scope This part of ISO 15859 specifies limits for the composition of helium and establishes the sampling and test requirements applicable for the verification of the helium composition. This part of ISO 15859 is applicable to helium, used in both flight hardware and ground facilities, systems and equipment, of the following types and grades. Type I: gaseous Grade A: purging and pressurizing helium; Grade F: purging and pressurizing helium; Grade J:
