**Product Overview**
**Stationery Tester * * is a high-precision quality testing equipment developed specifically for the stationery manufacturing industry, covering a full range of performance tests such as writing tools, paper, adhesive products, and student supplies * *, ensuring that products meet * * safety standards (such as EN 71, ASTM F963) * *, durability, and user experience requirements. Through intelligent detection technology, we help enterprises improve quality control efficiency, reduce return risks, and meet core needs such as export compliance, child safety certification, and brand reputation maintenance.

 **Core detection function**
1. ** Writing Performance Test**
Pen ink uniformity, writing length, and friction resistance (compliant with ISO 12757 standard).
Automatically simulate writing from different angles/pressures, detect ink breakage and liquid leakage issues.
2. ** Paper durability test**
Tear resistance (** TAPPI T414 ** ), flexural strength (** ISO 5626**), and ink absorption analysis.
Environmental simulation (temperature and humidity changes) to test paper deformation and fading.
3. ** Adhesive product testing**
Adhesive/tape bonding strength (** ASTM D3654 **), initial adhesion and holding adhesion cyclic testing.
Open close fatigue testing (such as correcting the performance of tapes and rubber sticks during repeated use).
4. ** Security compliance testing**
Sharp edge detection for children's stationery (** CPSIA **), screening for choking risk of small parts.
Toxic substance migration analysis (lead, phthalates, etc., in compliance with ** REACH regulation **).

**Applicable scenarios and customer groups**
Stationery manufacturer: Material verification and batch sampling before mass production to ensure product consistency.
Quality Inspection Laboratory: Provides data support for third-party certifications such as SGS and CE.
Educational supplies purchaser: Verify whether the supplier's products meet the bidding safety standards.
** R&D Center **: Optimize the design of new stationery (such as biodegradable pen holders and environmentally friendly adhesives). 

** Service and Support**
** Free program customization **: Configure equipment combinations according to enterprise testing needs (such as student backpack load testing).
** Global Compliance Support **: Provides guidance on market access testing processes for the European Union, the United States, Japan, and other countries.
