5. Test methods

5.1 Properties

5.1.1 Thermal shock resistance

Proceed as GB/T 4547 specified.

5.1.2 Internal stress

Proceed as GB/T 4545 specified.

5.1.3 Hydrolytic resistance of the interior surfaces

Proceed as GB/T 4548 specified.

5.2 Dimensions

5.2.1 Brimful capacity

Proceed as GB/T 20858 specified.

5.2.2 bottle height

Measure the bottle height with a vernier caliper or a height measuring device with the scale value of 0.02 mm

5.2.3 bottle outer diameter

Measure the outer diameter of the bottle with a caliper or OD measuring device with a scale value of 0.02 mm. Any point on the same cross section should meet the requirements.

5.2.4 bottle ovality 

Test the maximum and the minimum outer diameter of the body’s cross section as 5.2.3 specified. Bottle ovality should be calculated by Formula 1.

                               O=Dmax-Dmin————————————–（1）

In the equation：

O ——bottle ovality（mm）；

Dmax ——maximum outer diameter，unit（mm）；

Dmin ——minimum outer diameter，unit（mm）。

5.2.5 Body and bottom size

Measured with a scale gauge of 0.02.

5.2.6 Bottom thickness ratio

Measure the maximum thickness and minimum thickness of the same bottle as 5.2.5 specified. The ratio is the bottom thickness ratio.

5.2.7 Mouth nonparallelism

Measure the maximum height and minimum height of the mouth as 5.2.2 specified. Bottle nonparallelism should be calculated by Formula 2

                             △H=Hmax-Hmin ————————————（2）

In the equation：

△H ——mouth nonparallelism（mm）;

Hmax——maximum height（mm）;

Hmin——minimum height（mm）.

5.2.8 bottle flatness

The bottom of the bottle should be placed on the horizontal plate and stable, with each level 0.05mm incremental feeler from thin to thick piece by piece to measure the gap between the bottle and the plate. If the sample is not moving and feel to reach the inside of the bottle, then that the stopper has been stuffed to the maximum thickness of the plug can be stuffed into the flatness of the bottle.

5.2.9 Mouth inner and outer diameter

Measure with a special pass gauge or vernier caliper with the scale value of 0.02 mm.

5.3 Appearance

In the non-direct light, the distance for visual inspection should be around 30cm. If necessary, use vernier caliper, special measuring tools, feeler or magnifying glass to measure, or compared with the sealed sample.

5.4 Lead and cadmium dissolution

The lead and cadmium dissolution should be tested as GB/T 20858 specified.

 

6. Inspection rules

6.1 Inspection should proceed as the secondary sampling scheme described in GB/T 2828.1. Each batch should be consisted with products which have the same type, same composition, same size, same level, same period of time and same conditions. It may also required by both parties to the contract or agreement if necessary.

6.2 The inspection result should be expressed as the percentage of the unacceptable product. The inspection level (IL) and the acceptance quantity level (AQL) are shown in Table 7.

 Table 7

item	index	Inspection level （IL）	Acceptance quality level （AQL）
physicochemical properties	thermal shock resistance	S-3	0.65
	inner stress		1.0
Size Measurement	mouth nonparallelism  、mouth flatness、 external diameter of mouth	S-4	1.5
	capacity、height、Bottom thickness ratio		1.5
	thickness 、external diameter、roundness of bottle body		2.5
appearance	mouth defect、crack、 inside defect	Ⅱ	0.65
	bubble、stone、joint line、Smoothness、bottom defect		4.0

6.3 Hydrolytic resistance of the interior surfaces and the lead and cadmium dissolution should be normally tested once a week. In the event of a failure, the product is judged to be unacceptable and the product should be retrospective within a week prior to the date of sampling.

 

7. Logo , packaging, transportation and storage

7.1 Logo

Each package should be qualified or qualified label, specified with the name of the manufacturer, site, product name, specification, quantity, date of manufacture, inspection of the name of the packaging staff (code) and warnings such as “glass product” “fragile”, “handle with care “, etc.

7.2 Packaging

It is recommended to choose the appropriate packaging, such as wrap-shrink packaging, carton packaging, to reduce the impact of improper packaging on the quality of glass bottles. The packaging material should keep the product clean and not easily broken.

7.3 Transportation

The transportation must prevent violent vibration. The loading and unloading should be handled gently.

7.4 Storage

Storage should be dry, ventilated, no rain and snow invasion, to prevent moisture. They should be avoided to mix with the oil, acid and alkali substances. Storage height should be appropriate when stacked.
