The standards for compressors are set down by the International Organization for Standardization (ISO) around the world. The most powerful national body is the American National Standardization Institute (ANSI). Most of the other national bodies have standards which are basically adapted from the ones set by these two. The ISO has a technical committee (TC 118) which is dedicated to process compressors.
The standards set by these two bodies are in the following fields:
These provide standard provisions for the procedure, preparation, evaluation and assessment of performance tests which are carried out on various compressors. After this, is the acceptance test which is based on the performance test code. Acceptance tests demonstrate the fulfillment of the guarantees and order conditions specified on the product.
The other ISO and ANSI standards are product-specific varying as per product. The standards generally specify the requirements and give the recommendations for the material, design, fabrication, testing, inspection and preparation. They also provide the arrangements to be made in case of transporting and shipping the compressor.
This is one of the primary concerns for all units. The ANSI and the ISO provide detailed safety procedures and essentials for the proper and safe usage of these machines. The safety requirements enlist the type of equipment to be used while handling compressors, the power ratings of electrical supply, the maximum temperature and the pressure which the unit can sustain and other such conditions.In addition to the tests and procedures mentioned above there are some other standards too which might be set by the local bodies. In India the duty of standard formulation for compressors falls to the Mechanical Engineering Department (MED) of the Bureau of Indian Standards (BIS) which was formerly known as the Indian Standards Institute (ISI). As the MED is a member of ISO's TC118 most of the Indian standards are similar to those mentioned above.
