This is reflected in 15 ICC-ES and 3 IAPMO UES evaluation reports covering 200 product series — the most in the industry helping ensure product compliance for specifiers. When tested material properties exceed the specified properties, report holders are required to adjust the tested ultimate loads to account for the material over-strength. 1.2 This Code does not cover detailed for loads incidental to construction Some code officials, engineers, and contractors have added the two loads together when designing decks and others have just done as you suggest, basing the calculations on the larger of the two loads, either snow load or live load. For these connectors, we have been working diligently on re-evaluating construction connector loads to the new standard in order to update our product evaluation reports to the 2015 I-Codes. A single concentrated live load, L, of 3,000 pounds (13.35 kN) applied over an area of 4.5 inches by 4.5 inches (114 mm by 114 mm) and located so as to produce the maximum load effects on the structural elements under consideration. Both standards determine a connector's allowable load as the lowest of the following: The primary changes in ASTM D7147 are requirements to measure properties of the tested materials, such as steel strength, fastener strength and wood specific gravity. 17.
