How should electric heating and combustion tools be compared?

What should be compared first?

Electrical ratings, controls and instruction fields for three warming products

Identify the actual heating product before assigning a standard

The three records here describe electrically heated botanical or salt-filled products: a round mugwort belt pad, a blue sea-salt belt and a purple mugwort cushion. They use electrical heating elements with controllers and removable fabric or filling components. The catalogue sometimes uses moxibustion terminology for them, but the presence of mugwort and a power cable does not by itself establish medical-device classification or conformity to an electric-moxibustion standard. The purpose of this comparison is narrower: identify which electrical and instruction fields the actual records supply, which remain missing and which values belong to only one selected product.

The salt belt has stated mains ratings

The blue salt belt’s parameter panel states 220 V alternating current, 50 Hz and 105 W. Its picture shows a two-pin flat-pin plug. These values belong to that configuration, whose overall size is about 120 cm ±2 by 26 cm ±2. Suitability for another mains supply or another plug is not stated. A purchaser should therefore retain the nameplate values and the pictured connector in the sample brief, with any destination adaptation identified as a proposed configuration. Changing only the retail-box language does not change the electrical input rating or establish that a different power connection is approved.

The cushion shares a voltage but not a power rating

The purple cushion’s panel also states 220 V alternating current and 50 Hz, but its rated power is 45 W. Its cover is about 43 × 43 cm, with a stated ±2 cm dimensional variation. The source describes a two-pin flat-pin plug. The salt belt’s 105 W figure must not migrate to this cushion because the controllers have similar buttons. The cushion’s nine levels are described over 20–50°C, but no measured surface temperature is given for each level. Keep rated electrical power, the source-stated control range and an actual surface-temperature measurement as different fields.

The round belt pad does not supply the same electrical fields

The round floral belt pad is about 26 cm across with an overall belt length of about 101 cm. Its saved record names a heating chip, removable mugwort pad, controller, detachable cable and carry bag. It gives nine heat levels and a 30-, 45- or 60-minute timer, but no rated voltage, frequency, power or plug type. Do not fill those blanks from either of the other two records. A certificate image or an illustration of a heating element also does not identify the electrical rating of the exact assembled sample. These fields remain requests for the supplied nameplate and matching documents.

A controller chart is not a temperature calibration

The salt belt chart groups levels 1–3, 4–6 and 7–9 under different mode names on a scale around 40–80°C. The round pad illustration has an axis marked 20–70°C with a curve near 60°C. Neither record supplies a measured temperature for every level. The drawings must therefore remain illustrative rather than becoming an operating-temperature table. Even when a controller displays the same level number, the product construction, setting and measurement location still need identification before comparing results. No individual level temperature has been measured or approved as part of this editing work.

Timer buttons and high-setting restrictions are separate

All three records list 30-, 45- and 60-minute timer choices. Their written warnings also limit high-temperature use to 30 minutes and low-temperature use to 60 minutes. The existence of a 60-minute button does not remove the separate high-setting restriction. Carry the warning beside the controller explanation in the selected product’s instructions. These are manufacturer limits for the named products, not a clinical recommendation or a universal duration for heating devices. The records do not provide a measured shut-off test, restart behaviour or independent verification of the timing functions.

The detachable connection needs its matching parts

The records show a detachable power connection and warn that the connector must be fully inserted; they associate a poor connection with a short-circuit risk. The blue belt and purple cushion instructions also say to unplug the controller from the socket promptly after use and not leave the product powered when unused. These statements identify handling precautions, not a connector pinout or a universal replacement cable. A cable and controller that look similar are not shown to be interchangeable. The source calls for damaged power cables to be replaced by a qualified person using the dedicated cable or component, rather than giving a user repair procedure.

A certification statement has a configuration boundary

The round pad source states that the plug, cable and heating pad carry 3C/CCC certification and shows certificate images. The salt belt and cushion make certification statements but their saved material does not supply a certificate or test report. Preserve those different evidence states. None of them is an independently checked current approval for another destination or a modified assembly. The document request should identify the actual product, controller, cable and plug covered, the issuing document and its current scope. Do not describe Moxa Sourcing as holding a manufacturer’s certificate or treat a component statement as approval of every proposed kit.

A use photograph cannot cancel a written restriction

The blue belt video includes a scene of a person lying on the pack, and the purple cushion images show seated use. Their written precautions also prohibit covering the product while powered, use under bedding, folding or rolling during use. The saved records explicitly retain this unresolved conflict and ask for clarification, especially for powered seated use of the cushion. This comparison does not resolve it by choosing the more convenient image. The selected product needs consistent written instructions for its intended position before a buyer can use the scene as a handling example.

Moxibustion standards: combustion, electric and infrared scopes

Start with the combustion-device scope

ISO 18666:2021 concerns devices using moxa floss as their principal combustion material, including single-use and repeated-use forms remaining on or over the body. Its public scope covers construction, materials, performance, safety and the moxibustion material. It excludes direct-use moxa floss and noncombustion imitation devices. This scope helps identify a relevant document; it does not show that a particular box or its fuel has been tested.

The smokeless standard now has a 2026 edition

The ISO catalogue now lists ISO 21366:2026, published in September 2026, as the successor to the withdrawn 2019 edition. Its public scope addresses combustion devices claiming smokeless moxibustion, including smoke density, temperature, noxious gases and associated methods. Electro-moxibustion and infrared imitation devices remain outside that scope. A supplier referring to the older edition needs an edition-specific document review; changing a date in a sales description is not evidence of a new test.

Electric heating has a separate scope

ISO 21292:2020 addresses electric-heating moxibustion equipment. ISO’s catalogue says the edition was confirmed in 2026 and remains current. Its scope excludes the infrared equipment covered by ISO 20493 and the smokeless devices covered by ISO 21366. Accordingly, electricity in a product description is a starting classification clue, not enough to choose every applicable requirement or assert compliance. Identify how the equipment generates and transfers heat before reviewing the corresponding documents.

Infrared equipment is identified separately

ISO 20493:2018 is titled for infrared moxibustion-like instruments as medical devices. Its official catalogue entry says it was confirmed in 2024 and remains current. That scope is narrower than a general claim that any electrical heater is a moxibustion instrument. The entry identifies a standard to examine for an applicable instrument; it does not classify a selected product for a destination market or certify an unexamined unit.

Keep a change record with the selected heating system

A filtered combustion jar still has a lit cylinder, a fuel-retaining pin and ash-handling steps. The single-use mini jar and the dome jar describe smoke-filtering layers; those descriptions do not turn them into electrically heated products. Conversely, the electrical belt and cushion require their own power, controller and removable-part records.

Reuse one change sheet: changed part; old and proposed version; affected interfaces; revised instructions; new sample or document; and the person accepting the change. For a combustion tool, a different cap, filter, screen or fuel dimension can affect the assembly being reviewed. For a powered product, a different heater, controller or plug calls for the corresponding electrical documentation. Preserve the earlier version so that the replacement request and the actual received sample can be compared. A supplier’s proposed change and an accepted sample are separate stages.

Frequently asked questions (FAQ)

How should electric heating and combustion tools be compared?

Start with how heat is generated. A combustion holder needs its named fuel and ash-control arrangement; an electrical warmer needs its own input ratings, controller, cable, temperature information and care instructions.

Does a similar name prove compatibility?

No. Keep the exact model, selected option, dimensions and instructions together; similar names do not settle the interface.

Which details belong with a sample request?

Identify the tool version, selected parts, matching fuel, quantity and destination, with the instruction and packing fields that still need confirmation.
