Please provide me the list of Instrumentation and controls standards used in South Africa?
In South Africa, instrumentation and control standards are generally guided by international standards, with some additional specific regulations and codes that are unique to the country.
Some of the commonly used international standards include:
IEC (International Electrotechnical Commission) Standards
IEC provides a range of standards that are used globally, including in South Africa. Examples include IEC 61511 (Functional safety - Safety instrumented systems for the process industry sector), IEC 60870 (Telecontrol equipment and systems), and IEC 61131 (Programmable controllers).
ISO (International Organization for Standardization) Standards
These standards are also widely used in South Africa for a broad range of topics. ISO 9001 (Quality management systems) and ISO 55000 (Asset management) are examples of standards that may apply to instrumentation and controls.
ISA (International Society of Automation) Standards
These standards are used for various aspects of automation and control, including ISA-5.1 (Instrumentation Symbols and Identification) and ISA-18.2 (Management of Alarm Systems for the Process Industries).
ASME (American Society of Mechanical Engineers) Standards
While this is an American organization, its standards are recognized and used globally. Relevant standards include ASME PTC 19.3 (Thermowells) and various sections of the ASME Boiler and Pressure Vessel Code.
In terms of South Africa specific standards, the South African Bureau of Standards (SABS) is responsible for developing, promoting and maintaining South African National Standards (SANS). While SABS often aligns with international standards, there are also SANS that apply specifically to the South Africa.
