Test evidence, approvals and certifications · Lesson 3 of 4

Test evidence, approvals and certifications: methods and worked application

A documented method for matching evidence to a project, with an illustrative demand worked through AFS's wind function, Drexel's published ratings read against it, a range check, a coping caution and a submittal evidence matrix.

You will be able to: Apply a seven-step method to match evidence to a project: state the demand and its basis, read a published rating against it, run the range check, flag the coping caution, and build an evidence matrix with a verdict per row.

A seven-step matching method

A working method for this course, in seven steps: write the requirement and its basis, pick the test, find the report, match every part of the assembly, match the size, check date, edition and scope, then record accept, request or reject.

The steps are this course's own working method; the facts used at each step are cited on the slides that follow.

Glossary

Basis of comparison: The load basis a demand and a tested value are both on: strength level or allowable stress, with or without a factor, face or top. Evidence is comparable only when both sides share it.
Engineer of record: The licensed professional who sets the design loads and the factor of safety applied to a tested value. ES-1-2022 sets no factor in its text, and Drexel says the Design Engineer applies it.
Evidence matrix: A table with one row per requirement: the evidence offered, whether it matches, and a verdict of accept, request or reject.
Design pressure: In AFS's wind tool, the ASCE 7-16 pressure times 2.0, shown for comparison with a tested value. ES-1-2022 itself sets no factor in its text.
