Standards
This action of IEC 1241-2 specifies two last methods for determining the minimum ignition temperatures of dust. The methods are not suitable for use will having explosive properties.
In addition to the scope of International standard IEC 61326-1, this part specifies minimum requirements for immunity and emission regarding electromagnetic compatibility for in vitro diagnostic medical equipment equipment, taking into account the particularities and specific aspects of this electric equipment and their electromagnetic environment.
This part of IEC 61508 contains information and guidelines on IEC 61508-2 IEC 61508-3 - Annex A gives a brief overview of the requirements of IEC 61508-2 and IEC 61508-3 and sets out the functional steps in their application.
This part of IEC 61606 specifies the basic measurement methods of a linear PCM signal for an audio part of personal computers (PCs) and applies to both desktop and portable computers. The common measuring conditions and methods are described in IEC 61606-1 specific conditions and methods of measurement for PCs are given in this standard.
This clause of Part 1 is replaced by the following. This International standard deals with the safety of electric fans for household and similar purposes, their rated voltage being not more than 250V for single-phase appliances and 480 V for other appliances.
The scope of the International Building Code® (IBC®) includes all buildings except detached one- and two-family dwellings and townhouses up to three stories. For the most current adoptions details go to International Code Adoptions
The 2018 IBC contains many important changes such as:
- Accessory storage spaces of any size are now permitted to be classified as part of the occupancy to which they are accessory.
- New code sections have been introduced addressing medical gas systems and higher education laboratories.
- Use of fire walls to create separate buildings is now limited to only the determination of permissible types of construction based on allowable building area and height.
- Where an elevator hoistway door opens into a fire-resistance-rated corridor, the opening must be protected in a manner to address smoke intrusion into the hoistway.
- The occupant load factor for business uses has been revised to one occupant per 150 square feet.
- Live loads on decks and balconies increase the deck live load to one and one-half times the live load of the area served.
- The minimum lateral load that fire walls are required to resist is five pounds per square foot.
- Wind speed maps updated, including maps for the state of Hawaii. Terminology describing wind speeds has changed again with ultimate design wind speeds now called basic design wind speeds.
- Site soil coefficients now correspond to the newest generation of ground motion attenuation equations (seismic values).
- Five-foot tall wood trusses requiring permanent bracing must have a periodic special inspection to verify that the required bracing has been installed.
- New alternative fastener schedule for construction of mechanically laminated decking is added giving equivalent power-driven fasteners for the 20-penny nail.
- Solid sawn lumber header and girder spans for the exterior bearing walls reduce span lengths to allow #2 Southern Pine design values.
