Pressures exceeding 1000 psia demand materials with good mechanical stability. Absolute pressures (psia) must be used for gas rather than simply differential pressure. The feed pressure to each ultrafiltration membrane is 60 psia. The reactor vessel was rated to 1015 psia and measured 12 ft. 2 in. PSIA was founded by 20 member companies including Honeywell, GE Security, and Cisco. These security definitions apply to all PSIA nodes. It was raided by PSIA agents on 10 May 2007. The specification references the PSIA Service Model and IP Media Device specifications. The other four PSIA specifications correspond to domains in the security ecosystem. The PSIA can also not make arrests nor compel cooperation through any other means. The PSIA raided the headquarters of Fumihiro Joyu's Hikari no Wa on May 10, 2007.
