3-Step Identification of "Fake Flushable Wipes" YS-381 Test Standard Authority Guide

I. Industry Chaos: 90% of "Flushable Wipes" Are Misleading?

Recent explosive growth in wet toilet paper markets has exposed widespread "pseudo-flushable" traps:

❌ Fake Degradability: Labeled "flushable" but contains clogging synthetic fibers;

❌ Fake Testing: Substituting standard tests with (simple stirring), causing severe data distortion;

❌ Fake Certification: Counterfeiting international flushability logos (e.g., INDA/EDANA).

Real Case: A brand was fined ¥3.2 million for clogging municipal pipes; tests revealed wet strength retention rate >65% (far exceeding ≤25% standard)! 

II. YS-381 Standard: The "Litmus Test" for Authentic Flushable Wipes

Core Principle: Simulates toilet vortex to quantify physical fragmentation and chemical dissolution rates.

▶ Genuine flushable wipes must simultaneously meet (GB/T 40275-2021):

Fragmentation Rate: ≥90% (YS-381 test value);

Residual Area: ≤5%;

Pipe Suspension Time: ≤2 hours.

III. Step-by-Step Guide: 3 Steps to Unmask Evidence with YS-381

Step 1: Sample Prep — Eliminate "Cheat Samples"

Sampling Protocol:

Cut 100mm×100mm wipes (must include full pattern layer);

Soak in 25±1°C distilled water for 30s, shake off surface liquid;

▶ Yanshuo Tip: Inferior products often thicken patterns to resist tearing — focus testing here.

Step 2: Equipment Setup — Precision Simulation

Step 3: Result Judgment — Exposing 4 "Fake Flushable" Types

Filter post-test solution through 2mm standard sieve:

IV. Pitfall Avoidance: 3 Common Self-Test Mistakes

1. Mistake: Replacing professional equipment with "manual stirring bucket + timer"

Risk: Low RPM inflates fragmentation rate by >15%!

Solution: YS-381 features servo motor closed-loop control (see data comparison).

2. Mistake: Ignoring "wet strength agent" interference

Truth: Some manufacturers add polyamide epichlorohydrin to temporarily reduce wet strength (rebounds after 3h)!

Countermeasure: Conduct multi-cycle tests (Yanshuo equipment supports auto-extension).

3. Mistake: Neglecting pH correlation

Warning: Alkaline environments (pH＞8.5) accelerate fiber degradation, masking true performance!

Protocol: Calibrate solution to neutral pH before testing (free calibration by Yanshuo).

V. Decoding Authoritative Reports — 3 Critical Certifications

Verify third-party reports include:

1. Equipment Calibration ID (e.g., YS-381-CAL202407001);

2. Sieve Mesh Certification (GB/T 6003.1-2012 compliant);

3. Residue Micrographs (100x magnification for synthetic fibers).

Yanshuo Technical Service: YS-381 purchasers receive Flushability Verification Toolkit (standard sieve + pH strips + video guide).
