Mat - Bathroom mat and door mat
1 Scope
This standard specifies the terms and definitions, product classification, requirements,
test methods, inspection rules and signs, packaging, transportation, storage of mats used
in bathrooms and in front of doors (hereinafter referred to as "mats").
This standard is applicable to the quality judgment of small block mats, which are used
in bathrooms and in front of doors, etc., made of chemical fiber, cotton, wool, blended
fiber mat surface raw materials. The mats, which are made of other fiber materials, can
also be used as a reference.

3 Terms and definitions
The following terms and definitions apply to this standard.
3.1
Mat
Machine-made or handmade mat, piled or not piled, backed or unbacked, small
carpet tiles, of textile fibers.
It is mainly placed in front of doors of bathrooms and toilets. Depending on the place
of use, it plays various roles such as decoration, pollution resistance, water
resistance. Dimensions are not specified.
Note: Mats are different from block mats. Block mats are mainly placed in the center of the
room or in a certain part of the room. Most of them are decorative pattern products, which
have different sizes AND are often used as mats on top of the mats.
3.2
Static slip resistance
The maximum frictional force as reflected is the anti-slip ability, at the moment
when an object in a static state on a horizontal plane is moved.
3.3
Coefficient of friction
6 Test method
6.1 Appearance quality
Inspectors shall carry out visual inspection and hand feeling inspection on the mat
surface, mat edge, mat backing, according to the requirements in Table 2.
6.2 Internal quality
6.2.1 Test conditions (unless otherwise specified)
The standard atmosphere for humidity conditioning and testing adopts the standard
atmosphere for secondary testing, which is specified in GB 6529, which as a
temperature of (20 ± 2) °C and a relative humidity of (65 ± 3)%.
6.2.2 Humidity conditioning (unless otherwise specified)
Before the test, under the standard atmospheric conditions for the test specified in 6.2.1,
put the mat surface of the specimen upwards; place it flat and in a single block; keep
the humidity conditioning for at least 24 h.
6.2.3 Specimen
Cut the specimen, according to the method specified in QB/T 1087.
6.2.4 Fiber type and content of mat surface
When fiber content analysis is required, the test shall be carried out according to GB/T
2910 or GB/T 2911, based on different components.
6.2.5 Pile thickness and pile length on mat base
The pile thickness shall be tested according to QB/T 1555.
The method of measuring the length of the pile is to insert a small ruler with a scale
into the pile to the base of the mat; read the length of the pile, accurate to 0.5 mm.
6.2.6 Pile mass per unit area on mat base
Carry out the test according to QB/T 1188.
6.2.7 Mat dimensions
Make measurement according to the method specified in QB/T 2214.

if one of the following situations occurs.
a) Resumption of production after suspension of production;
b) Where there are major changes in the raw materials and processes of the product;
c) Contract agreement;
d) Where the national quality supervision agency makes a request.
7.2 Inspection items
7.2.1 Exit-factory inspection items
The exit-factory inspection items include appearance quality (Table 2) and dimensions
(length x width) in internal quality (Table 1), all of which must be 100% inspected.
7.2.2 Type inspection items
The type inspection items include all items specified in the appearance quality (Table
2) and internal quality (Table 1). It shall be randomly sampled from the qualified
batches of the exit-factory inspection.
7.3 Sampling requirements
Sampling is randomly selected in batches and blocks. The size of batches and quantity
of samples are shown in Table 4. For appearance quality inspection, all randomly
selected samples are inspected; for internal quality inspection, it is randomly selected
from samples that pass the appearance quality inspection.
for bathroom mats;
g) Washing method;
h) The standard number implemented by the product;
i) Product grade, inspection certificate.
8.2 Additional information
a) The main specifications of the mat (mat base/pile thickness/length and pile quality,
etc.);
b) Mark the antibacterial sign on a conspicuous position of the product;
c) Other information.
8.3 Packaging sign
Contents that need to be marked on the packaging sign:
a) The name of the manufacturer;
b) Product name and variety;
c) Dimensions of the mat;
