This document specifies the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply. It does not apply to chemical service glass-enamel and apparatus enamel.

 

This document defines important terms used in the heat treatment of ferrous materials. Annex A provides an alphabetical list of terms defined in this document, as well as their equivalents in French, German, Russian, Chinese and Japanese. Table 1 shows the various iron-carbon (Fe-C) phases.

 

This document specifies requirements for the following hand powered cranes defined in Clause 3: - hand chain blocks; - lever hoists; - jaw winches; - hand powered trolleys supporting lifting machines; NOTE Hand powered trolleys placed on the market on their own and intended to be used with products within the scope of this document are considered as interchangeable equipment as defined in Directive 2006/42/EC. - drum winches; - pulley blocks. This document deals with the following significant hazards, hazardous situations or hazardous events relevant to hand powered cranes, when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer: - mechanical hazards; - thermal hazards; - material/substance hazards; - ergonomic hazards; - hazards associated with the environment in which they are used. This document does not cover hazards related to the lifting of persons. This document is not applicable to hand powered cranes for: - use in ambient temperature outside the range of - 10°C to + 50°C, however for some lifting medium the minimum temperature will be higher than -10 °C; - use in direct contact with food stuffs or pharmaceuticals requiring a high level of cleanliness for hygiene reasons; - handling specific hazardous materials (e.g. explosives, hot molten masses, radiating materials); - operation in an explosive atmosphere. This document is not applicable to hand powered cranes manufactured before the date of its publication.

 

This document specifies terms and definitions, product requirements and test methods for the construction and performance of loft ladders. Loft ladders are applicable for infrequent temporary internal access in both domestic and commercial premises.

 

This document specifies dimensions, materials and performance requirements, including test methods, for combined temperature and pressure relief valves, of nominal sizes from DN 15 to DN 40, having working pressures ) from 0,3 MPa (3 bar) to 1,0 MPa (10 bar). Combined temperature and pressure relief valves control and limit the temperature and pressure of the water contained in a hot water heater to the valves rating pressure and a temperature not exceeding 100 °C and will prevent water to steam formation when other temperature controls fail. Combined temperature and pressure relief valves are classified having a maximum opening temperature range from 90 °C to 95 °C for class A and 75 °C to 80 °C for class B. They are not intended to act as an expansion valve and do not control cold water flow. Alone it does not constitute the control functions for a water heater. A combined temperature and pressure relief valve is an independently mechanically operating device, therefore operating without an external energy source. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information, see Annex B).

 

This document specifies the terms and definitions related to the structures for mine shafts, used throughout ISO 19426. Terms used in mining can vary from conventional engineering usage, and they vary quite considerably between different countries. For this reason, alternative terms are provided in many of the entries. The preferred terms, given in bold type, are those used throughout ISO 19426. It is assumed that users of this document are familiar with mining, so common terms with normal dictionary usage are not defined. Also, no definitions are provided for terms that can be widely used in mining but are not explicitly used in ISO 19426.

 

This document specifies the design loads and the design procedures for the structural design of headframe structures of mine shafts and their components for permanent and sinking operations. The headframe includes all structures and their foundations, that are required at the head of all vertical and decline mine shafts for the purposes of supporting and installing winding and sinking ropes, conveyance guides, rope guides and rubbing ropes, equipment for loading and unloading conveyances, safety devices, as well as ancillary sinking and maintenance equipment. The headframe also includes the bank and sub-bank levels. This document does not cover matters of operational safety or layout of the headframe. This document adopts a limit states design philosophy.

 

This document specifies the design loads and the design procedures for the structural design of stages and components of stages. The loads specified in this document are not applicable for the design of stage ropes or sheaves. Rope sizes are determined in accordance with other standards. This document does not cover matters of operational safety, or layout of the sinking stage and other mechanised methods of shaft sinking that shall be addressed using a rational method. This document adopts a limit states design philosophy.

 

This document specifies the loads, the load combinations and the design procedures for the design of shaft system structures in both vertical and decline shafts. The shaft system structures covered by this document include buntons, guides and rails, station structures, rock loading structures, brattice walls, conveyance and vehicle arresting structures and dropsets, services supports, rope guide anchor supports and box fronts. Rock support is excluded from the scope of this document. This document does not cover matters of operational safety, or the layout of the shaft system structures This document adopts a limit states design philosophy.
