1. Standard System Architecture

my country's current vacuum cleaner safety standards adopt a dual-standard matching system:

1. Basic standard: GB 4706.1-2005 "Safety of Household and Similar Electrical Appliances Part 1: General Requirements"

• Covers common safety requirements for all household appliances

• Provisions for basic provisions such as protection against electric shock and mechanical hazard protection

2. Special standard: GB 4706.7-2014 "Safety of household and similar electrical appliances - Particular requirements for vacuum cleaners"

• Equivalent to IEC 60335-2-2:2009 international standard

• Supplement 23 special technical requirements for vacuum cleaner characteristics

• The latest international standard IEC 60335-2-2:2019 adds 5 new technical clauses

II. Key Security Technical Requirements

1. Electrical safety performance

• Insulation resistance: ≥2MΩ between live parts and shell (500VDC)

• Withstand voltage test: 1250V/1min without breakdown (reinforced insulation part)

• Leakage current: ≤0.75mA (Class I equipment)

• Grounding resistance: ≤0.1Ω (grounding terminal and easily accessible metal parts)

2. Mechanical safety protection

• Stability test: 10° tilt platform without tipping over

• Mechanical strength: No dangerous sharp edges after 0.5J impact of spring impactor

• Protection of moving parts: brush head opening ≤ 6mm (to prevent fingers from getting involved)

3. Thermal safety performance

• Temperature rise limit:

  • Metal housing: ≤60K (ambient temperature 25°C)

  • Plastic handle: ≤35K

  • Air outlet area: +10K relaxation value is allowed

• Abnormal test: No fire risk after motor stall for 1 hour

III. Major updates to the 2019 edition of the international standard

1. Scope of application expansion

• Explicitly includes battery-powered and dual-power models

• Added Ash Vacuum Cleaner special category

2. Test method optimization

• Input power measurement: Allows forced shutdown with closed air inlet

• Temperature rise test: Introducing 4N pressure probe contact method

• Handle strength: 5-10s progressive loading test method

3. Specific requirements for ash vacuum cleaners

• Structural requirements:

  • A metal pre-filter (mesh size ≤ 1mm²) must be configured

  • Dust box wall thickness ≥ 0.35mm

  • Hose length ≤ 2m

• Material flame retardant grade:

  • Dust box GWFI ≥ 850℃ or GWIT ≥ 875℃

  • Upstream components must pass the needle flame test (GB/T 5169.11)

• Fire protection test:

  • Simulated burning paper ball test (70-120g/m² A4 paper)

  • No flame is required and it complies with Clause 19.13

IV. New requirements for signs and instructions

1. Symbol Conventions

• The symbols 0434A (high temperature warning) and 0790 (cleaning and maintenance) in ISO 7000-2004 must be marked side by side

2. Ash vacuum cleaner warnings

• Clearly limited to cold ash collection

• Prohibited items:

  • Absorb high temperature/burning materials

  • Use a paper dust bag

  • Place on flammable surfaces

• Mandatory requirements:

  • Empty the dust box before and after each use

  • Dedicated model identification

5. Key points of key testing methods

1. Handle strength test

• Load calculation:

  • Appliance weight + nominal maximum dust collection capacity

  • Water-absorbing models need to be filled with water

• Force application method:

  • 75mm length uniformly distributed load

  • 5-10s gradual loading to nominal value

• Acceptance criteria:

  • No breakage of structural parts

  • Slight surface indentation is allowed

2. Material flame retardancy test

• Glow-wire test:

  • te-ti≤2s at 850℃/30s

  • The thickness of the sample is consistent with the actual component

• Alternatives:

  • GWIT≥875℃

  • or UL94 V-0 grade material

3. Filter protection test

• Use IEC 61032 C-type probe (4mm diameter)

• The filter must not be penetrated under a force of 3N

• The metal filter needs to be visually inspected for weaving density

VI. Compliance Implementation Recommendations

1. Design control points

• Dual power supply models require independent assessment of battery mode risks

• Ash collection functionality must be developed as a special model

• The material of the air outlet area needs to consider the +10K temperature rise margin

2. Testing Notes

• The new version of the temperature rise test requires a dedicated pressure probe device

• The paper ball combustion test should be carried out in an explosion-proof cabin

• Handle testing needs to simulate actual force distribution

3. Document management requirements

• The technical documentation must include proof of conformity to all alternative standards

• Key safety parts (such as filters) must retain material certification

• Warning signs should be printed permanently
