Title:Emergency Placarding - Internal and External
Issuing Committee:S-9 Cabin Safety Provisions Committee
Scope:This Aerospace Recommended Practice (ARP) provides criteria for the development and standardization of placards containing easily understood signs, symbols and/or instructions for locating and operating exits and emergency equipment which might be used or operated by cabin occupants and rescue personnel under emergency conditions. In addition, this ARP gives guidance in the selection and development of warning labels. The placards are intended to be seen and understood by occupants within and, in the case of external exit placards, by persons outside the airplane.【英文标准名称】:Determinationofparticlesizedistribution-Singleparticlelightinteractionmethods-Part4:Lightscatteringairborneparticlecounterforcleanspaces
