## Abstract

The invention relates to uplift testing apparatus and method used to provide a quality control test to confirm adequate bonding by the mortar or adhesive to the tile and underlayment or mechanically attached tile roof systems, and, more particularly it is a direct tensile load that is applied by pulling up on the edge of the tile by using a tile testing scale

## Claims

### Claim 1

A portable tile testing apparatus for measuring the uplift force and the displacement of a tile and said tile is tested for uplift comprising of:
a handle;
a 90-degree hook;
a connecting link;
a load cell;
and a displacement scale.

### Claim 2 (depends on 1)

The 90-degree hook of claim 1 comprising of hook and a hook body, a hook connector and hook end configured to lift a tile.

### Claim 3 (depends on 1)

The Handle of claim 1 comprises of a grip configured to accept the hand of an inspector and a connector to connect the handle to the load cell such that it allows 360-degree rotation about the connection to said load cell.

### Claim 4 (depends on 1)

The connecting link of claim 1 attach it to said load cell on the proximal end of the link and a connector to attach said 90-degree hook to said distal end of the link.

### Claim 5 (depends on 1)

The displacement scale of claim 1 connected to the load cell to measure the distance of deflected motion of tile when force is applied to said grip of said handle and said 90-degree hook tip is placed under the edge of said tile.

### Claim 6 (depends on 1)

The displacement scale of claim 1 wherein the displacement scale material selected from the group consisting of aluminum, teflon, nylon, plastic and carbon.

### Claim 7 (depends on 1)

The displacement scale of claim 1 wherein the displacement scale is selected from the group consisting of an LVDT a dial indicator, digital dial indicator and calipers.

### Claim 8 (depends on 1)

The load cell of claim 1 wherein the load cell is selected from the group of instruments consisting of spring weight sensors, single point load cell, digital load cell and beam load cell.

### Claim 9

The method of measuring the lift of a tile using a portable tile testing apparatus comprising of placing a 90-degree hook under said tile front lip and lifting on said tile and reading the force on the scale of the load cell and the distance on the scale of the displacement scale and taking a photograph of said force on the scale of the load cell and said distance on the scale of the displacement scale.
