Relevant Standards

ISO 11064-2 2001 Principles for the Arrangement of Control Suites. The second part of this 

ISO 11064-3 1999 Control Room Layout. The third part of ISO 11064 establishes ergonomic principles for the layout of control rooms. It includes requirements, recommendations, and guidelines for control room layouts, workstation arrangements, the use of off-workstation visual displays, and control room maintenance. The standard offers guidance under topics including architectural and operational considerations, workstation arrangement, off-workstation shared displays, circulation of personnel, and maintenance access. 

ISO 11064-4 2004 Layout and Dimensions of Workstations. The fourth part of ISO 11064 specifies 

ISO 11064-5 Displays and Controls. The fifth part of ISO 11064 is still under development.

It is good practice to keep concentrations of airborne nickel in any chemical form as low as possible and certainly below the relevant standard. Local exhaust ventilation is the preferred method, particularly for powders, but personal respirator protection may be employed where necessary. In the United States, the Occupational Safety and Health Administration (OSHA) personal exposure limit (PEL) for all forms of nickel except nickel carbonyl is 1 mg/m. The ACGIH TLVs are respectively 1 mg/m for Ni metal, insoluble compounds, and fume and dust from nickel sulfide roasting, and 0.1 mg/m for soluble nickel compounds. The ACGIH is considering whether to lower the TLVs for all forms of nickel to 0.05 mg/m, based on nonmalignant respiratory effects in experimental animals. 

Tests for elements such as arsenic, lead, and copper are specified in the relevant standards. The methods specified are usually of the colorimetric or atomic absorption types. 

The biotechnology (qv) industry has no formal standards for equipment manufacture and quality control as of this writing. The American Society of Mechanical Engineers (ASME) set up a task force in 1989, for developing relevant standards for biotechnology equipment.

In the tables of relevant Standards in this book while the latest editions of the standards are provided, it is possible that revised editions have become available. With the advances of technology and/or its application, the updating of standards is a continuous process by different standards organizations. It is therefore advisable that for more authentic references, readers should consult the relevant organizations for the latest version of a standard. 

Type tests are conducted on the first machine of etich type or design to determine the characteiislics and demonstrate its compliance with the relevant Standards. These tests provide a standard reference for any subsequent similar machine. The following ire Ihe type tests according to I EC 60034-1 ... 

The type of duly defines the capacity of a switch or a contactor by the value of the current and the p.f. of the associated circuit, it can make or break on fault. For value.s of currents and p.f. for different duties, refer to the relevant standards as noted above.

To comply with the rated insulation level, all the current-carrying components forming part of the assembly should have clearances and creepage distances according to their relevant standards whereas busbars and busbar connections must have the distances noted below.

Before creating a fault condition, to obtain the required /sc the impedance of the test circuit is adjusted so that the required fault current is obtained in all the phases on creating a short-circuit. To provide the required thermal effect (/sc /). the duration of test, /, is then adjusted accor-dingly. The relevant standards therefore stipulate that the test current may be higher or lower than required and can be compensated by adjusting its duration, i.
