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…

1.1 This Standard applies to Class 1, 2, 3, 4, 5, and 7 powered lift trucks—their design, operation, and maintenance. In addition, certain clauses apply to Class 6 vehicles, non-powered high-lift trucks, and personnel and burden carriers. See Annex B for a listing and description of classes. 1.2 The purpose of this Standard is to promote lift truck safety and minimize the risk of injury to…
