Standards
The widespread use of scaffolding systems, along with the profound importance that they earned in modern applications such as civil engineering projects and temporary structures, led to the definition of a series of standards covering a vast number of specific issues involving scaffolding. Among the standards there are:
- DIN 4420, a DIN standard divided in 5 parts which covers the design and detail of scaffolds, ladder scaffolds, safety requirements and standard types, materials, components, dimensions and loadbearing capacity.
- DIN 4421, a DIN standard which covers the analysis, design and construction of falsework
- 29 CFR Part 1926: Safety Standards for Scaffolds Used in the Construction Industry from the U.S. Occupational Safety and Health Administration (OSHA), with an accompanying "construction eTool"

Famous quotes containing the word standards:
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
