Packaging Methods

Bottles 1. Dimensions 1999

The dimensions of beer and ale bottles are critical to the smooth operation of packaging machinery. Specifications and tolerances must be set in accordance with the requirements of the equipment and the glass vendor’s process capability. This method measures height, outside diameter, out-of-perpendicular, identification marks, glass distribution, weight, locking ring “A” diameter, reinforcing ring “B” diameter, width of locking ring, throat “I” diameter, and finish.

Bottles 2. Defects

This method provides general definitions to aid in understanding terms expressing the degree or seriousness of a bottle defect or an accumulation of defects.

Bottles 3. Color

This method measures the amber color of bottle glass spectrophotometrically and by redness ratio.

Bottles 4. Capacity

This method determines the overflow and fill point capacities of beer and ale bottles.

Bottles 5. Surface Protective Coatings

This method evaluates the performance characteristics of durable lubricating coatings on glass in two ways: lubricity and coating quality. The first is a measure of the coefficient of friction between coated glass containers, while the second is a measure of the abrasion protection provided by the coating. Permanently coated nonreturnable bottles can be evaluated by the dry and wet rub test procedures.

Bottle Closures 1. Defects Glossary and Classification

This glossary contains general definitions that specify the terms expressing the degree or seriousness of a defect or accumulation of defects for plastic-lined crowns and closures, including closure shell defects, plastic liner defects, and lithography defects.

Bottle Closures 2. Test Pressure

This method determines the amount of pressure a bottle crown will withstand when subjected to a uniformly increasing internal pressure with the crown applied to a steel bottle finish and to a standard glass bottle finish; the amount of pressure a 28-mm topside pilferproof closure will withstand when subjected to a uniformly increasing internal pressure with the closure applied to a steel bottle finish and to a standard glass bottle finish; the amount of pressure a plastic-lined convenience two-way crown applied to GPI 500 series finishes will withstand when subjected to a uniformly increasing internal pressure; and tests the integrity of the bottle-closure seal.

Bottle Closures 3. Gas Retention Capability of Crowns

This method measures the gas-retention capability of cork-lined and plastic-lined crowns.

Bottle Closures 4. Lithography Resistance to Pasteurization Conditions for Steel Crowns and Roll-On Pilferproof Aluminum Closures

This test simulates the exposure of a crimped crown or an applied roll-on pilferproof closure to the caustic solutions that are present in a conventional pasteurizer. Some lithographic materials may be less tolerant to exposure than others. However, crown manufacturers usually have prescreened these coating materials for best pasteurization bath resistance. This test is used only as a confirmation test when problems are noted on crowns or closures that have exited pasteurization during production conditions.

Bottle Closures 5. Removal Torque Procedure

This method estimates the average and variation of removal torques from a given lot of aluminum closures or a given lot of crowns and a given lot of bottles.

Bottle Closures 6. Crimp Determination Test -- Crowns

This method determines crimp diameter after crown application. Proper crimp is essential to prevent leakage.

Cans 1. Defects Classification and Glossary for Seamless Two-Piece Cans

Can and end defects require classification to reduce misunderstandings of terms, while at the same time expressing the area of influence for the defect or accumulation of defects. This method defines terms used to describe can and end defects.

Cans 3. Dimensions

This method measures metal gauge thickness of cans and ends, coated or uncoated; flange width; and the countersink depth of a filled, closed can.

View Method

Cans 4. Ends

This method measures the curl opening of beverage ends and the fit of an end to a seaming chuck and determines the force required to open ring-pull-ends.

View Method

Cans 5. Capacity

This method measures the overflow capacity of cans and the headspace of a can at stated contents.

Cans 6. Enamel Rater for Evaluating Metal Exposure

This method provides a rating of can quality in terms of metal exposure and a location site of the exposure by using an enamel rater. Average, minimum, and maximum metal exposure values and the standard deviation are determined.

Cans 7. Beverage Can Terminology

This document defines the standard terminology used to describe different parts of a beverage can and can end. It is designed to be used for reference for methods that use can terminology.

Cans 8. Copper Sulfate Test

This method determines whether there are any exposed metal surfaces on the interior of containers coated with a polymer material. It is designed primarily for the testing of aluminum cans and ends coated with internal coating (IC), but it can be used for containers made with other metals such as steel. A galvanic reaction occurs when the copper from the copper sulfate is deposited on the surface in locations where the surface is not covered with IC. This method detects potential pinholes and pores in the IC or places where the container may contain improper coverage of the IC on the interior.

Kegs 1. Keg Terminology

This method describes the common keg sizes, parts of kegs, and valves used in the brewing industry. It is intended to provide a reference to members, so that there is a common language for discussing kegs.
