Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws and regulations which restrict chemical content in electronic products. These systems include standard operating procedures that ensure that restricted substances are not utilized in our manufacturing operations, laboratory analytical validation testing, and an internal auditing process to ensure that all standard operating procedures are complied with. 2.4 Reference documents SCSI Commands Reference Manual Seagate part number: 100293068 SAS Interface Manual Seagate part number: 100293071 Applicable ANSI SAS documents SFF-8323 3.5" Drive Form Factor with Serial Connector SFF-8460 HSS Backplane Design Guidelines SFF-8470 Multi Lane Copper Connector SFF-8482 SAS Plug Connector ANSI INCITS.xxx Serial Attached SCSI (SAS) Standard (T10/1562-D) ISO/IEC 14776-xxx SCSI Architecure Model-3 (SAM-3) Standard (T10/1561-D) ISO/IEC 14776-xxx SCSI Primary Commands-3 (SPC-3) Standard (T10/1416-D) ISO/IEC 14776-xxx SCSI Block Commands-2 (SBC-2) Standard (T10/1417-D) ANSI Small Computer System Interface (SCSI) Documents X3.270-1996(SCSI-3) Architecture Model Specification for Acoustic Test Requirement and Procedures Seagate part number: 30553-001 Package Test Specification Seagate P/N 30190-001 (under 100 lb.)
