ISO 19973-4:2014 applies to manually adjustable and remote-piloted pressure regulators, both relieving and non-relieving. It does not apply to pressure regulators that have a permanent bleed.
ISO 19973-4:2014 also specifies test equipment and failure criteria (threshold levels) for tests to assess the reliability of pneumatic pressure regulators.
