Article (4)
Metrological Requirements for Pre-packages
1. Label Card:
a. The label shall be affixed to the Pre-package in a way that is non-removable, written in
clear text, and placed on the main side of the package when displayed in the usual manner,
in a location separate from other information. The label shall include at least the following
information:
1. The product name and the commercial name of the product. The product name may
be omitted if the product is wrapped in transparent material and is commonly
recognised by the consumer. However, the product name shall be clear and not cause
any confusion or mislead the consumer in any way;
2. All information necessary to trace the Pre-packages from the consumer to the packer,
importer, or manufacturer;
3. The nominal quantity;
4. The unit of measurement; and
5. Any other mandatory information required by the technical regulations relevant with
the product.
b. When the quantity statement is in terms of weight, volume, length, area, or number, and
is not sufficient to provide the consumer with complete information, the manufacturer,
packer, or importer shall provide sufficient and clear information about the quantities of
the product (e.g., longitudinal weight, concentration per unit of volume or mass).
c. The following words and expressions shall be avoided when stating the nominal quantity
of the product:
1. Minimum;
2. Not less than;
3. Average;
4. Approximately;
5. Nearly; or
6. Any other words of a similar nature.

d. In the case of Pre-packages bearing the phrase "economical package" or similar, the actual
quantity of the product shall be clear to the consumer.
e. If the pre-package contains more than one label distributed in different locations on the
can, the requirements for the product label shall comply with the provisions hereof and
the relevant regulations.
f. Pre-packages may bear their own conformity mark, provided that they meet the
mandatory requirements for this mark.
g. The label shall be in Arabic, and any other language may be used unless the technical
regulations or specific instructions for the product state otherwise.
h. In addition to the label requirements outlined herein, the label shall also meet the
mandatory requirements specified in the technical regulations for the label or the
product itself.
i. The value of the nominal quantity shall be followed by the unit of measurement, and the
minimum height of the numbers and letters used on the package shall not be less than
the values specified in Table (1) attached hereto. The font may be of the largest possible
size.
j. The ministry or the authorised entity may request the manufacturer, packager, or
importer to remove, add, or modify any information on the label in a manner that ensures
better consumer protection or eliminates any confusion.
k. The nominal quantity shall be expressed in whole numbers (e.g., 1 kg, 2 kg) or decimal
numbers (e.g., 0.5 kg, 1.5 kg), and it shall not be written in fractional form (e.g., 1/2 kg or
1/2 1 kg).
l. Quantities less than one unit shall be written with a maximum of three decimal places.
m. If the quantity of the product is written on the label without being preceded by any other
phrases such as "net weight" or "net volume," etc., then this quantity is considered to be
the nominal quantity subject to metrological control.
n. In solid products preserved in liquids, the drained weight shall be clearly stated.
o. For products packaged in pressurised cans and dispensed as a spray, the nominal value
of the product shall be equal to the amount of the liquid phase contained in the package.

p. If the Pre-packages contain a specific number of identical items (e.g., (5) cans of table salt
or (10) cans of sugar), or non-identical products (e.g., a large can containing smaller cans
of salt, sugar, and spices) that cannot be sold separately from each other, the label shall
clearly state the number of these items and the nominal quantity of each, or the total
nominal quantity of the product, ensuring that the label clearly reflects this without any
ambiguity.
q. If liquid products are packed in transparent packages with graduated markings that
indicate the actual quantity inside, and the consumer can see the product inside under
normal conditions, with graduations and accuracy that meet the mandatory
requirements, the nominal quantity may be omitted from the label.
2. Measurement Units:
a. The legal units of measurement and their symbols shall be used correctly when expressing
the quantity of the product in the pre-package.
b. The nominal quantity shall be expressed in mass units for solid, viscous, bulk products,
and products consisting of a mixture of solid and liquid products, as well as the solid part
in a mixture of solid and liquid products. The nominal quantity of liquid materials shall
also be expressed in volume units at a reference temperature of (20°C).
c. Liquid products may be sold by mass unit or solid products by volume unit if it is the
common trade practice, provided that it ensures better consumer protection.
d. The nominal quantity shall be expressed using the units and symbols approved in the
Technical Regulations for Legal Measurement Units as outlined in Table (2) attached
hereto, or a combination of these units as case may be.
e. The general rules for writing legal measurement units shall be observed according to their
specifications and technical regulations, especially the following rules:
1. There shall be a single gap between the value of the nominal quantity and the unit of
measurement; and

2. The plural form shall not be used when using the symbols for legal units of
measurement, nor shall the letter "s" be used after the unit symbol when using a
language other than Arabic.
3. Requirements for Verifying the Quantity of the Product in Pre-packages:
a. Criteria for rejection and acceptance:
1. The average actual quantity of the products shall not be less than the nominal
quantity.
2. The number of deficient packages in the inspection batch shall not exceed the values
specified in Table (4) attached hereto.
3. The inspection batch shall not contain any package in which the amount of deficiency
exceeds twice the allowed deficiency from the nominal quantity of a single can (2xT1),
as specified in Table (3) attached hereto.
b. Inspection Batch Requirements and Sampling:
1. When ready samples are taken from the production line, the size of the inspection
batch shall be equal to the maximum production capacity per hour, with no limitations
on the batch size.
2. When samples of pre-packages are taken from the company production facility (not
the production line), the size of the inspection batch shall be equal to the maximum
production capacity per hour or 100,000 samples, whichever is smaller.
3. If samples of the cans are taken at the packaging facilities where the actual hourly
production rate or the original batch size is unknown, data shall be obtained from the
representative of the inspected facility. The maximum production limit shall not
exceed 100,000 samples, and the batch shall be homogeneous. In general, the legal
metrology inspector shall take samples in proportion to the production size.
4. Table (4) attached hereto specifies the minimum sample size required for inspection,
the acceptable number of samples with an error (T1), and the correction factor for the
samples.

c. The legal metrological control on the actual quantities of pre-packages shall be carried out
as follows:
1. Sampling from supplier warehouses, whether from the end of the production line,
storage location, or point of sale; and
2. Quality control records.
d. Legal metrological control on the actual quantities of pre-packages shall be conducted
according to the following situations:
1. Inspection programme plans by authorised entities for locally manufactured or
packaged and imported products. In this case, the fees related to metrological services,
as stipulated by the applicable regulations in the ministry, shall be collected;
2. Upon request from the supplier, and in this case, the fees related to metrological
services, as stipulated by the applicable regulations in the ministry, shall be collected;
and
3. In response to complaints received by the ministry or the authorised entity, or as part
of surprise inspection plans, with no fees charged unless non-compliant materials are
detected. In such cases, the manufacturer, packer, or importer is liable for the fees
related to metrological services, as stipulated by the applicable regulations in the
ministry.
e. Tests shall be conducted either at the inspection site or by collecting samples and sending
them to laboratories accredited by the ministry or the authorised entity.
f. The actual quantity shall be determined with the consideration of the following:
1. When determining the actual volume of liquid contained in the container, the liquid
volume shall be calculated at a temperature of (20°C);
2. If the product is preserved in a liquid medium to be removed, the actual quantity of
the product shall be the amount of the product in the pre-package after reaching
equilibrium in the solution preparation process and after filtering the liquid medium;
3. In the case of frozen products, the actual quantity shall refer to the product excluding
the packaging material, ice, and frost;
4. Protective gas or air shall not be considered part of the actual quantity of the product;

5. When calculating the actual volume using the gravimetric method and using weights
with a density of (8) g/mL, the actual volume of the product can be practically
calculated using the following equation:
𝑚𝑚.
𝑃𝑃−0.0012× 0.99985 = V
Where:
V = Actual liquid volume.
m = Mass of the liquid.
p = Density of the liquid.
6. For the purposes of determining the actual weight of products packed in a liquid
medium and the weight of frozen products, the annexes in the specification (OIML
R87) shall be referenced.
g. Legal metrological control on pre-packages shall be carried out in two ways:
1. Non-destructive testing method: This is the generally used method, except when the
standard deviation (10) for ten empty packages is equal to or exceeds (20%) twenty
percent of the permissible shortage from the nominal quantity of a single package
(T1); and
2. Destructive testing method: This method is used when it is not possible to conduct
tests using the non-destructive method.
h. The empty weight of the package shall be determined as follows:
1. If the legal metrological control on pre-packages is conducted at the packaging site,
(10) ten empty containers shall be taken, and the arithmetic mean and standard
deviation for them shall be calculated; and
2. If the standard deviation is less than (20%) twenty percent of the permissible
deficiency from the nominal quantity of a single package (T1), this value shall be
adopted for all empty packages in the batch. Otherwise, the empty weight for each
individual package shall be calculated after it is emptied of its product.
i. The number of deficient packages shall be calculated according to the values specified in
Table (3) attached hereto, by subtracting the permissible deficiency for the package from
the nominal quantity. Any sample containing less than this value shall be considered a
deficient package.

j. When calculating the permissible deficiency in the package resulting from the use of the
percentage, the following cases should be considered:
1. If the nominal quantity is less than or equal to (1,000) grams, millilitres, or any
declared unit of volume or dimensions, the values shall be rounded up by (0.1) for
containers packed by weight, volume, length, or area. For containers packed by count,
the result shall be rounded to the next whole number; and
2. If the nominal quantity is greater than (1,000) grams, millilitres, or any declared unit
of volume or dimensions, the values shall be rounded to the next whole number.
k. The number of pre-packages in which the deficiency exceeds twice the permissible
deficiency shall be calculated according to Table (3) attached hereto.
l. An estimated value may be added to the permissible deficiency in a single package due to
the following circumstances:
1. Variables caused by deviations that cannot be avoided in measuring the actual
quantity, which may occur during the filling process;
2. Variables caused by weather conditions during transportation, storage, and display of
the packages under acceptable conditions for preserving these packages; and
3. Variables due to the nature of the packed material or the package.
m. The actual quantity may be measured directly using weighing machines or volume
instruments, or indirectly, as in the case of liquids, by determining the weight and density
of the liquid. Regardless of the method used, the error resulting from measuring the actual
quantity shall not exceed (20%) of the permissible deficiency for the pre-packages.
n. Legal metrological control on pre-packages with variable nominal quantities shall be
conducted in the same manner as control on packages with fixed nominal quantities,
except for testing the actual quantity rate of the pre-packages.
o. In the case of legal metrological control on pre-packages available in markets, or control
on imported packages from which sampling is difficult due to the low number of
containers in the imported batch, or due to the inability to conduct non-destructive tests,
or due to the lack of capacity to conduct tests at the appropriate speed, random samples

Packages
13
shall be collected to the minimum possible extent from each type, for example. The entire
batch is considered non-compliant in the following cases:
1. If one or more pre-packages are found with a deficiency exceeding twice the
permissible one;
2. If the pre-packages do not meet the mandatory requirements for the label; and
3. If it is proven that the actual quantity rate in the pre-packages is less than the nominal
quantity, after collecting expanded samples of no less than (20) twenty containers.
4. Misleading Packages
a. The capacities of the pre-packages used shall accommodate the actual quantities without
creating ineffective slack-fills, provided that this void space do not exceed what is specified
in the technical regulations and product specifications, if applicable.
b. The design of pre-packages shall be free from any cavities, protrusions, pockets, bulges, or
any design that could mislead the consumer into thinking the container contains a larger
quantity than its actual content. Additionally, the container shall not be displayed in a
manner that makes it appear to contain more than its actual quantity.
c. The pre-package shall not contain parts filled with materials that occupy space in the
package capacity without justification.
5. Slack-Fill:
A void space in the pre-package is allowed in the following cases:
a. Requirements of the machinery used in sealing the contents of the pre-packages;
b. Sedimentation that is unavoidable during transportation and handling of the product;
C. The need
