Low Emission Standards

1. ISO 15848

ISO 15848 standardizes the measurement, testing, and evaluation procedures for industrial valve fugitive emissions. This standard is divided into two parts. ISO 15848-1 defines the test procedures for valve type testing, and ISO 15848-2 specifies the requirements for the manufacturing of valve products.
