Elements present at concentrations above the upper limit of the working ranges can be determined with additional

BS EN 15151-2 on safety requirements for braking devices is useful for:

This International Standard specifies bridge requirements that will secure a safe and efficient lookout on those seagoing ships having a fully enclosed bridge

The connectors mentioned in BS EN 60603-7-4 are intermateable and interoperable with other IEC 60603-7 series connectors as defined in Clause 2 of IEC 60603-7

Air filters for general ventilation - Technical specifications, requirements and classification system based upon particulate matter efficiency (ePM) Ingestion-build-79769 Elements present at concentrations above1 Scope This part of ISO 16890 establishes an efficiency classification system of air filters for general ventilation based upon particulate matter (PM). It also provides an overview of the test procedures, and specifies general requirements for assessing and marking the filters, as well as for documenting the test results. It is intended for use in conjunction with ISO 168902, ISO 168903 and ISO 168904. The test method described in this part of ISO
