Luggage inspection: children's luggage inspection standards and methods

Children's luggage is specially designed for children's backpacks, schoolbags or trolley luggage, generally refers to children under 14 years of age to use luggage products. Compared with the adult use of luggage has a set of more stringent quality requirements, then theChildren's Luggage InspectionWhat are the criteria and methodology?

 One,Classification and applicable standards of children's luggage

Children's luggage is divided into two main categories based on age of use:

Bags for children under 6 years of age in category Ⅰ.

Class II bags for children aged 6 years and above to under 14 years old.

This categorization determines different levels of safety requirements, with Class I products having more stringent safety requirements due to the younger age of the user.

China's current core standard is GB/T 41002-2022 "General Technical Specification for Children's Luggage", which was formally implemented on October 1, 2022, and is the main basis for the production, inspection and supervision of children's luggage. In addition, a series of related standards need to be met, including:

GB 20400, GB 21550, GB 31701, GB 18401 and other standards on material safety

GB 6675.2-2014 "Toy Safety Part 2: Mechanical and Physical Properties" in the related requirements

Hygienic and ergonomic provisions in WS/T 585-2018 Hygienic Requirements for School Bags for Primary and Secondary School Students

For imported and exported products, it is also necessary to comply with the standards of the destination country or region, such as the restriction requirements for chemical substances under the European Union's REACH regulation.

Two,Core standard requirements

(i) Material safety requirements

Material safety in children's luggage isinspection of goodsThe primary focus is on the need to strictly control the content of hazardous substances:

Three,Inspection Methods and Processes

(i) Sampling methods

Children's luggage inspection usually use sampling test:

Sampling in accordance with GB/T 2828.1

Sample size is determined by lot size and AQL (Acceptable Quality Level), generally AQL Level 2 is used.

(ii) Visual inspection

1. Overall inspection::

Check whether the overall shape is correct, there is no deformation, skew phenomenon

Check whether the body of the package is full, whether the arc is natural, and whether the paste is smooth and obedient

Check whether the box is upright and smooth, there is no high and low phenomenon

2. Fabric Inspection::

Check the fabric for defects such as broken warp, broken weft, skipped threads, jumping threads, etc.

Check whether the fabric color is uniform, there is no obvious color difference, color flower

Check fabric surface for stains, blemishes, scratches and other damage

Touch the fabric with your hand to feel the texture and check for linting and hooking.

3. Process Inspection::

Check whether the stitch is even and straight, and whether there are empty stitches, missed stitches, skipped stitches and broken threads.

Check whether the gap of the box mouth meets the standard and whether the fittings are firmly installed.

Check whether the metal fittings are evenly plated, with or without corrosion, blistering, skinning

Check whether the zipper is flat and straight, whether the zipper head is firm, and whether the zipper plate has any scratching phenomenon.

(iii) Safety performance tests

1. Widget Testing:.

Checking small parts for risk of accidental swallowing with a small parts tester

Tensile testing of small parts: Tensile and torque reasonable abuse test according to GB 6675.2-2014 in 5.24

Check whether the decorative parts, such as hairballs, are detached after the tension test and whether the detached part passes the hairball tester.

2. Sharp Edge and Tip Testing::

Check the product for dangerous sharp edges or tips that can be reached with a special instrument.

Checking wires and rods for risk of breakage and for dangerous sharp tips after testing

3. Gap Test::

Check the safety of round holes in rigid materials with 6mm and 12mm diameter round rods.

Check clearance safety of moving parts with 5mm and 12mm diameter round rods.

4. Rope and Strap Test::

Check that the tow rope width is > 12mm and that it is detachable

Perform tension tests on shoulder straps, lanyards, etc. to check for breakage under the specified tension.

(iv) Physical property tests

1. Sewing Strength Test:.

Sample of 100mm x 60mm taken from the main load-bearing area (length of 100mm in the direction of the suture line).

Tested with tensile machine, clamping distance 60mm, tensile speed (100±10) mm/min, record the maximum force value.

Check whether the specified strength requirements are met (Ⅰ ≥ 240N, simple paragraph ≥ 120N)

2. Oscillatory shock test:.

Simulate the actual use of the bag, 300 times for each handle and side handle.

Check for broken handles, cracked cases and loose parts after the test

3. Walking Performance Test:.

Simulates the state of tilted walking or upright walking while pulling a bag.

After the test, check whether the walking wheel rotates flexibly, without jamming and deformation.

Measure wheel wear, not more than 2mm.

4. Tie Rod Performance Test:.

Check smoothness by repeatedly stretching the tie rod

Press the lever at a 45-degree angle to test the strength.

Perform fatigue test on tie rods to check for deformation, jamming, loosening, etc.

5. Accessory Performance Test:.

Zipper durability test: Repeatedly open and close the zipper to check whether there are lost teeth, wrong teeth, damaged

Lock durability test: repeatedly open and close the lock, check whether the normal work, the combination lock has no stagnation, garbled code

Plastic snap-in durability test: open and close the snap-in repeatedly to check whether it works properly.

(v) Marking inspections

1. Marking integrity check::

Check for product age range or category labeling

Check whether there is information on the body material and whether the labeling is consistent with the body material

Check for manufacturer information, specifications, etc.

2. Marking accuracy check::

Check whether the content of the labeling is consistent with the actual product

Check that the implementation standard number is correct

Check safety warnings for accuracy and clarity

IV. Determination and processing of inspection results

According to the test results, the product is divided into two categories: qualified and unqualified, of which unqualified can be divided into:

1. serious flaw::

Safety hazards that may cause injury to children, such as the risk of small parts falling off, dangerously sharp edges, excessive levels of hazardous substances, etc.

Serious non-compliance with major performance indicators, such as insufficient seam strength, tie rod breakage, etc.

Seriously defective products are judged to be unqualified, and are not allowed to leave the factory or sales

2. major flaw::

Defects that affect the function of the product but do not constitute a potential safety hazard, such as unsmooth zippers, wheel jamming, etc.

The main defective products need to be reworked and repaired, after re-inspection and qualified before leaving the factory

3. minor flaw::

Slight defects that do not affect the use of the product safety and the main function, such as minor jumps in secondary parts, minor color difference, etc.

Depending on the number and severity of defects, they can be judged as satisfactory or requiring rectification

Upon completion of the inspection, a detailed inspection report should be issued, including.

Basic Product Information

Inspection based on standards

Various test results

Description of nonconforming items and photographic evidence

Consolidated findings

For unqualified products, rework, repair or scrap treatment should be carried out according to the report requirements to ensure that the product meets the standard requirements before entering the market.

Children's luggage inspection work is a great responsibility, the inspector must be strictly in accordance with the standard requirements, meticulous and conscientious to carry out each inspection to ensure that each product can provide children with a safe and comfortable experience.
