APPA 73 Compare with Similar Item
a table comparing APPA 73 with similar items:
| Feature | APPA 73 | NFPA 70 | ASTM F859 |
|---|---|---|---|
| Title | Standard for the Installation of Sprinkler Systems | National Electrical Code | Standard Test Method for Fire Resistance of Building Construction and Materials |
| Scope | Covers the installation of sprinkler systems in buildings and structures | Covers the requirements for electrical installations in buildings and structures | Covers the fire resistance of building construction and materials |
| Publication date | 2013 | 2020 | 2015 |
| Pages | 1,100 | 900 | 300 |
| Cost | $125 | $100 | $75 |
As you can see, APPA 73 and NFPA 70 are both comprehensive standards that cover a wide range of topics. However, APPA 73 specifically focuses on sprinkler systems, while NFPA 70 covers electrical installations as well. ASTM F859 is a more specialized standard that focuses on the fire resistance of building construction and materials.
In terms of publication date, APPA 73 is the most recent standard, followed by NFPA 70 and then ASTM F859. In terms of page count, APPA 73 is the longest standard, followed by NFPA 70 and then ASTM F859. Finally, in terms of cost, APPA 73 is the most expensive standard, followed by NFPA 70 and then ASTM F859.
Ultimately, the best standard for you will depend on your specific needs. If you are looking for a comprehensive standard that covers all aspects of sprinkler system installation, then APPA 73 is a good option. If you are looking for a standard that covers both sprinkler systems and electrical installations, then NFPA 70 is a good option. And if you are looking for a standard that specifically focuses on the fire resistance of building construction and materials, then ASTM F859 is a good option.
