This Jordanian Standard specifies minimum requirements for filtering half masks as respiratory protective devices to protect against particles except for escape purposes. Laboratory and practical performance tests are included for the assessment of compliance with the requirements. .
This Standard specifies the fi ltering half mask requirements for use as non-powered air purifying respirators.
This European Standard specifies minimum requirements for filtering half masks as respiratoryprotective devices to protect against particles except for escape purposes.Laboratory and practical performance tests are included for the assessment of compliance with therequirements.
This European Standard specifies the performance requirements, test methods and marking requirements forvalved filtering half masks incorporating either gas or combined filters as respiratory protective devices except forescape purposes. It does not cover gas filtering half masks which do not have valves or are fitted only withexhalation valves. It does not cover devices designed for use in circumstances where there is or might be anoxygen deficiency (oxygen less than a volume fraction of 17 %).Laboratory and practical performance tests are included for the assessment of compliance with the requirements.
This European Standard provides guidance on the best practice for establishing and implementing a suitable respiratory protective device programme. It is published to provide a Europe-wide baseline for the selection, use, care and maintenance of respiratory protective devices. It provides guidelines for preparing national guidance in this area. The guidance contained in this European Standard is not intended to be exhaustive, but highlights important aspects to which attention should be given. The recommendations in this European Standard will help to comply with national legislation on this subject where it exists, or with European legislation. Respiratory protective devices used exclusively in diving and at increased or reduced atmospheric pressures are not covered by this guidance.
This European Standard defines and gives the specifications for normal hardening hydraulic road binders, produced in a factory and supplied ready for treatment of materials for bases, sub-bases and capping layers as well as earthworks, in road, railway, airport and other types of infrastructures. It includes the mechanical, physical and chemical requirements and the classification of these binders based on their compressive strength at 56 days. It also includes the conformity criteria and evaluation procedures to be applied by the manufacturer.

This European Standard refers to filtering devices with a hood for personal escape from participate matter, carbon monoxide and other toxic gases produced by fire. It specifies minimum requirements for this device which is for single use. It does not cover devices designed for use in circumstances where there is or might be an oxygen deficiency (oxygen less than 17 % by volume).nTwo types of devices are specified; namely, those designed to be carried on the person and those designed to be stored.nThis standard specifies devices primarily designed for adult users. Some devices may not be suitable for children.nLaboratory and practical performance tests are included for the assessment of compliance with the requirements.
