Spring dial scales verification

Spring scales are a popular type of watch scale widely used in daily life. With its convenience and fairness, spring scales ensure that measuring becomes easier and more accurate. The spring scale calibration process is also simple, helping users trust in the accuracy of the measurement results.

Spring scales (also known as spring dial scales) are a popular type of scales widely used in everyday life. Due to its convenience and much cheaper price compared to electronic scales, it is a common choice for many people.

Spring scales come in two types: tabletop and hanging, usually with accuracy class IIII and the ability to weigh up to 200kg (according to OIML R76-2006)

- Spring dial scales are a popular measuring device used in everyday life. Here are some applications of spring scales in life:

• Measure the weight of small objects such as food, jewelry, coins, etc.
• Used in testing tensile and compressive forces of industrial components such as construction, automobile manufacturing, machinery, parts such as springs, gear tubes, etc.
• Used in balance testers and indicators as pressure gauges.
• In the manufacturing industry, spring scales are used to measure the destructive force of materials, helping in the process of checking product quality.
• Spring scales are used in the quality industry to help measure the load-bearing capacity of equipment and materials.
• In medicine, spring scales are used to measure the amount of powder or liquid medicine needed to treat a patient.

- Therefore, it can be said that a spring scale is one of the versatile measuring tools, having many applications in daily life as well as in industry and medicine.

Measurement standard:

• The scale has a total weight equal to Max, with an accuracy class of M2.
• The scale determines the error (1 ÷ 500) g; (1 ÷ 10) kg, with an accuracy class of M2

Before conducting the inspection, the following preparations must be performed:

• Fill in the general information at the beginning of the inspection form;
• Place the scale neatly, check the balance of the scale through the plumb bob and check the normal operation of the scale according to technical documents.
• Standard weights must be fully assembled, clean and within the validity period of the inspection.

- Check the scale label, stamp position, and inspection stamp;
- Check the completeness of weighing details and parts;
- Record inspection results in the verification record.

• Clock face, scale, pointer
• Other details and parts

​- Record inspection results in the verification record.

If a spring scale meets the requirements of this procedure, it will be issued a verification certificate and verification seal and/or a verification sticker as required. The verification seal must be affixed (or the verfication sticker must be affixed) at locations that prevent the adjustment of the accuracy of the scale.

If a spring scale does not meet one of the requirements of this procedure, it will not be issued an verification sticker, and the old verification seal (if any) will be removed.

The verification cycle of a spring scale is 24 months.
