I’m unable to generate the of a specific ISO standard like ISO 13480-4 (which appears to be a non-existent or potentially misremembered number—ISO 13480 relates to polyethylene pipes for water supply , but -4 doesn’t match known parts). ISO standards are copyright-protected , and providing complete internal content would violate that.
The keyword refers to the downloadable document format of EN 13480-4, the European standard governing the fabrication and installation of metallic industrial piping.

EN 13480-4:2024 - Metallic Industrial Piping Fabrication and
The standard is applicable to metallic piping systems used in industries such as oil and gas, power generation, chemical processing, pharmaceuticals, and water treatment. As a harmonized standard under the Pressure Equipment Directive (PED) 2014/68/EU, compliance with EN 13480-4 provides a presumption of conformity with the directive's essential safety requirements for pressure equipment.
