Document from the Office of the State Administration for Market Regulation

Market Supervision Special Issue [2025] No. 52

Elevator car specific thickness gaugeTIME-N7

The General Office of the State Administration for Market Regulation on Further Improving Residential Housing

Notice on the Renovation of Old Elevators

Market Supervision Bureaus (Departments, Committees) of all provinces, autonomous regions, municipalities directly under the central government, and Xinjiang Production and Construction Corps:

In order to do a good job in updating old residential elevators supported by extra long term special treasury bond funds, and fully ensure the safety and convenience of residents, we hereby notify the following matters:

1、 Balancing safety and economy, effectively ensuring the quality and safety performance of elevators

1. Floor doors, elevator doors, and cars

(1) The floor sills and car fenders of the landing doors and sedan doors should be made of metal materials;

(2) The updated panel materials for metal layer doors, elevator doors, and cars shall consist of at least one layer of single metal sheet with a nominal thickness of not less than 1.5mm; The nominal thickness of the metal material panel of the reserved metal layer door shall not be less than 1.2mm; the engagement depth of the lower retaining device of the reserved layer door shall not be less than 15mm.

2、 Inspection equipment: Elevator panel thickness measuring kit, including the following contents:

Specification requirements

purpose

Digital Caliper

indication error±0.01mm、

Calibration or verification certificates must be obtained.

The direct measurement method is for detectionThe fundamental guarantee of work.

Ultrasonic thickness gauge

indication error±0.05mm（10mmWhen), calibration or inspection must be obtainedCertification is required. It is necessary to have the function of "coating thickness measurement" activated under painted conditions (including double-sided painted), without the need for polishing, to accurately measure the thickness of the metal body. It is also necessary to have real-time capabilitiesAScan signal display function (instead ofSnapshotAsweep”）In order to search for corrosion pits. At least the following accessories should be provided: a single crystal delay block probe

(.≤4.5mm）Used for thickness measurementSearch for corrosion points and pits; One 'unequal thickness step test block' and two 'unequal thickness anti paint test pieces' (used to verify the instrument's ability to measure paint thickness). It is recommended that the thicknesses be500uAbout m, and1000uAbout m

Quick measurement,

The part that cannot be measured by the caliperMeasure the position,

On the premise of having paint, there is no needPolish and accurately measure the thickness of the body.

-Can display A-scan waveform for easy echo analysis and measurement of complex workpieces

-It has multiple measurement methods and can be set to blank to shield aftershocks or clutter;

-The instrument can adapt to various types of probes

-Penetrating coating measurement, layer by layer thickness measurement, and simultaneous display;

-Resolution of 0.001, 0.01, 0.1 millimeters is optional in any mode (or 0.0001, 0.001, 0.01)

Inches optional);

-Gain adjustment range 0-99dB;

-Adjustable voltage and variable pulse width square wave pulse generator;

-Equipped with single value B-scan display function;

-Equipped with alarm function, the upper and lower limits of the alarm can be freely set;

-Display mode with differences and maximum and minimum values;

-Can store up to 500000 measurement values and waveforms;

-Users can activate the fast measurement mode up to 20 times per second;

reverse measurement of sound velocityBased on the thickness of an object with unknown sound velocity, measure the sound velocity of the object in reverse
