Industrial Code

When constmction is complete, the pipeline must be tested for leaks and strength before being put into service industry code specifies the test procedures. Water is the test fluid of choice for natural gas pipelines, and hydrostatic testing is often carried out beyond the yield strength in order to reHeve secondary stresses added during constmction or to ensure that all defects are found. Industry code limits on the hoop stress control the test pressures, which are also limited by location classification based on population. Hoop stress is calculated from the formula, S = PD/2t, where S is the hoop stress in kPa (psig) P is the internal pressure in kPa (psig), and D and T are the outside pipe diameter and nominal wall thickness, respectively, in mm (in.). 

The relationship of codes and standards to the regulatory framework should be cleady understood. By themselves, industry codes and standards have no authority. Flowever, an examination of both regulations and codes shows that the governmental jurisdictions that have authority over tanks usually... 

Fans are tested by the manufacturers to the applicable industry codes of ASHRAE 51 and AMCA 214—latest editions. Tests are conducted between shut-off (no flow at... 

Factory tests establish the pressure head, power, efficiency and NPSH over the complete flow range the pump can deliver running at design speed. British Standard, DIN standard or ANSI standard codes or national variations from such main codes lay down the manner of test procedure, and a minimum requirement is quite often defined by industry codes such as API 610. This is not the place to discuss instrument accuracy, as the codes lay down the limits possible from conventional instruments. There are two main classes of test the commercial requirements normally possible in the maker s test plant and high-accuracy tests that are only possible by using substandard instruments and very sophisticated techniques.

The laboratory shall identify the inputs that affect the design and development of the laboratory processes and facihtate their effective and efficient performance. Inputs are defined from external as well as internal needs and expectations. External inputs are drawn from customers, suppliers, users of the laboratory output, statutory and regulatory requirements, international or national standards, industry codes of practice etc. Internal inputs are drawn from policies and objectives, needs and expectations of people, technological development, past experience etc. 

SIC Standard Industrial Code. Prepared by the United States Office of Management and Budget. Silica Gel A regenerative absorbent consisting of the amorphous silica. Used in dehydrating and in drying and as a catalyst carrier. 

The issue of too much water being added to juices has largely been addressed through the application of a minimum solids content (measured in degrees Brix). Many countries now have in place a minimum Brix value for various juices. These minima are backed either by legal statute or industry code of practice. They normally apply to juices prepared by adding water to concentrate and not to not from concentrate products. 

Prominence, or a significant presence, in alternative energy and supporting fields. (See the following Industry Codes section for a complete list of types of businesses that are covered). 

This book refers to the following list of unique industry codes, based on the 1997 NAIC code system (NAIC is used by many analysts as a replacement for older SIC codes because NAIC is more specific to today s industry sectors). Companies profiled in this book are given a primary NAIC code, reflecting the main line of business of each firm.

Industrial codes and standards for hydrogen are thus strict for a good reason. Some 22 percent or more of hydrogen accidents are caused by undetected hydrogen leaks.44 And this is despite the standard operating procedures, protective clothing, and electronic flame gas detectors provided to the limited number of hydrogen... 

The American Society for Testing and Materials (ASTM) provides standards, compatibility testing, and tests for mechanical properties, recommended practices and procedures as well as codes for polymeric materials. The various industry codes and standards are summarized in Table 4.95.
