On-site inspections of products

On-site inspections at supermarkets and other facilities

Inspection scenery

Supermarkets sell a large number of foodstuffs. Some individual products have "weight". Indication of proper weight, "use of proper measuring instruments" and "appropriate weighing" are indispensable. It takes every day to maintain "appropriate weighing", such as horizontal installation of measuring instruments, correct tabi bags, and re-measurement of products that evaporate moisture.
The Yokohama Metrology Laboratory conducts on-site inspections and provides guidance on the display of the weight of products at supermarkets in Yokohama City so that consumers can purchase products with peace of mind.

On-site inspection of the product quantity is performed by extracting products from the meat, fresh fish, fruits and vegetables, and prepared dishes that are closely related in our dietary habits.

Indication of "weight" is very convenient for consumers to judge "how much is required" and "which of the product" in their daily consumer life . In addition, "unit price" (value of the product based on unit price of 100g, etc.) enables comparison of products across departments. Therefore, it is very important that the "weight" is appropriate.

Specific products and volume tolerances

According to the Measurement Law, 29 products that should be regulated for consumer protection from among products that are likely to be weighed and sold as "specified products."
For this "specific product", the error "quantity tolerance" allowed in the display of "weight" is individually regulated.
