Description
Meets the standard:
Gauge manufactured in accordance with the requirements of EN 50075 – Figure 4.
Purpose:
Used for the measurement and verification of plug and socket dimensions in household and similar applications.
It is applicable for testing whether a single-pin plug can be inserted into a socket, thereby posing an electric shock hazard.
Test principle:
The gauge, as shown above, is placed between the pins and left to stand for 1 minute. Under its own weight, the gauge must not come into contact with the mating surfaces of the plug.

YLZ-100 Microcomputer-Controlled Electro-Hydraulic Servo Curbstone Flexural Testing Machine
The YLZ-100 concrete curbstone flexural‑compressive testing machine is used to determine the flexural strength and flexural load of linear curbstones with a length of 1000 mm, as well as the compressive strength of curved curbstones and L‑shaped curbstones with a straight cross‑section. In accordance with JC/T 899‑2016 Concrete Curbstones, it can also be employed to conduct experimental studies on the flexural and compressive strengths of other materials.
The microcomputer-controlled high‑ and low‑temperature electronic universal testing machine consists of the testing machine mainframe, fixtures, a high‑ and low‑temperature chamber, and computer software. The temperature chamber is slid into the mainframe; after opening the chamber door, the specimen is secured in the dedicated fixture. The chamber then heats or cools until the specified temperature is reached.
