1.1 This Standard specifies minimum requirements for the design, construction, installation, and operation of lifts that are to be specifically used by persons with physical disabilities travelling between fixed points of a building or structure, including a private residence, with a view to safeguarding against risk of accidents associated with the operation of such equipment. 1.2 This…

1.1 This Standard applies to protective headwear for industrial, construction, mining, utility, and forestry workers. It defines the areas of the head that are to be protected and includes basic performance requirements for dielectric strength, impact attenuation, penetration resistance, passive retention (stability), and shell flammability and liner ignition resistance. 1.2 This Standard…

1.1 This Standard covers material, manufacturing, and class dimensional requirements for seasoned wood poles and reinforcing stubs that are primarily intended for the support of electrical power or communication lines. 1.2 This Standard does not cover requirements for wood poles intended for use in structures such as bridges and buildings. 1.3 This Standard does not cover requirements for the…

1 Scope and application 1.1 Scope This Standard specifies provisions for the planning, design, and maintenance of surface drainage systems within northern community boundaries. Provisions for drainage outside the community boundary are not covered by this Standard. Note: Specific resources and expertise are required to address drainage provisions outside the community boundary. These resources…

This part of ISO 18134 describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and may be used when high precision of the determination of moisture content is necessary. The method described in this International Standard is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported…

IEC 61557-8:2014 specifies the requirements for insulation monitoring devices (IMD) which permanently monitor the insulation resistance RF to earth of unearthed a.c. IT systems, of a.c. IT systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as of unearthed d.c. IT systems with voltages up to 1 500 V d.c. independent from the method of measuring.…

IEC 61557-9:2014 specifies the requirements for the insulation fault location system (IFLS) which localizes insulation faults in any part of the system in unearthed IT a.c. systems and unearthed IT a.c. systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c., as well as in unearthed IT d.c. systems with voltages up to 1 500 V d.c., independent of the measuring…

ISO 15845:2014 specifies the minimum functional and safety requirements for enclosed self-propelled boarding vehicles designed for transporting and boarding/de-boarding persons with reduced mobility onto/from the main deck or upper deck of main line civil transport aircraft on which they are travelling as a passenger. The intent of ISO 15845:2014 is not to specify equipment design, but rather to…

ISO 26422:2014 specifies a method of determining the shear stability of polymer-containing lubricating oils by the four-ball machine as specified in ISO 20623, but using a tapered roller bearing. The test results allow prediction of the in-service permanent viscosity loss. NOTE Other International Standards exist which evaluate viscosity loss of polymer-containing oils. The method…

1 Scope 1.1 Mitigation techniques and other actions This Standard covers the following mitigation techniques to maintain permafrost or remediate permafrost degradation around existing buildings or structures: a) site techniques that consist of i) shading; ii) drainage and grading; and iii) ground cover and snow management; b) foundation techniques that consist of i) ventilation; ii)…
