Quanzhou leather goods and other material testing

Quanzhou leather goods and other material testing
Fujian Zhongkai Testing Technology Co., Ltd. is a third-party professional scientific and technological testing organization specializing in testing ambient air, noise, water environment, radiation, materials, soil environment, etc. At present, it has the largest and most complete sub-testing laboratories in the same field, including chemical analysis air testing rooms, gas chromatography testing rooms, physical testing rooms, building energy-saving testing rooms and quality management rooms and other professional laboratories. It has high-tech hardware instruments such as high-precision gas chromatography analyzers, formaldehyde analyzers, environmental radon detection measuring instruments, spectrophotometers, and power frequency radio frequency electromagnetic radiation detectors imported from home and abroad.
Our laboratory professionals have undergone strict training and technical assessment, and have obtained qualifications. They can conduct testing independently, accurately and efficiently, and must accept professional ethics, service ethics, dedication to work, compliance with laws and regulations, etc. Quality education takes science and impartiality as its sole purpose. The test data issued are authentic and reliable. The test and evaluation are not restricted or affected by the outside world or leading institutions to ensure the impartiality of the third party in the laboratory. It mainly provides indoor and outdoor environmental air quality, water We provide testing technical services in the areas of environment, noise, indoor lighting, limits of harmful substances in artificial panel materials, public occupational health, electromagnetic radiation, soil environment, etc. Since its establishment, it has had a good reputation and influence in society and has been praised by many customers. . . .

Compared with before: bring cement, sand, stone and other raw materials,
, aggregate
and sand. Materials submitted for inspection include: concrete (compression resistance, impermeability, total strength, etc.), steel bars (raw materials, welding, mechanical connections, etc.), cement, aggregates, mortar, wall raw materials, admixtures, waterproof materials Wait. Ishitori. Not higher than the inspection batch, the cement sample sampling point is at least above the point. The inspection order form states the parts, specifications, manufacturers, etc. for Quanzhou leather goods and other material testing. The manufacturer, brand, variety, grade, quantity, factory serial number, etc. should be indicated on the inspection order form.
, wall quality materials
Randomly select blocks to send samples. Indicate the location, strength level, and molding time on the test block (engraved with nails). Self-mixing concrete is made of test blocks for each shift or tray. Tens of millions of dollars.
Impermeability: Take test blocks as a group, and each group of test blocks will represent tens of thousands of sintered porous bricks for testing of Quanzhou leather goods and other materials.
Compared with before: Bring cement, sand, stone and other materials. The inspection order form shall state the location, strength level, specifications, manufacturer, etc., and what you need to know about sample submission for material testing
. Witnessing sampling testing: A copy of the witness’s certificate must be provided when sending samples for the first time.
The compressive strength block test blocks are divided into groups.
, backfill soil
The outer foundation trench is backfilled, and each batch is inspected and the test blocks are not higher than the group. Each time a sample is sent, the witness needs to add a signature to confirm, and the depth of each layer,
, material testing sampling methods and quantity:
, cement:
according to the same manufacturer, the same grade, the same variety, the same Cement with batch number and continuous entry,
, steel bars
Raw materials: hot-rolled smooth round (ribbed) steel bars: root drawing and root bending for each specification. Represents the quantity,
, concrete:
The compressive strength is based on block test blocks.
Represents the quantity: the same brand, the same furnace tank number, the same specification, the same delivery status is not larger than the batch, the sintered ordinary bricks represent the quantity,
Welding: flash butt welding, air pressure welding: root pull per specification , Root Bend: The inspection order sheet states the location, design strength, slump design requirements and specifications of each raw material, manufacturer, etc. Quanzhou leather goods and other material testing. The representative quantity of concrete small hollow brick blocks is 10,000 pieces,
The representative quantity: no more than 10,000 pieces is discussed as an inspection batch. The inspection order form shall indicate the location, strength level, consistency, specifications of each raw material, manufacturer, etc., and the circumference shall be taken in groups (only ring knives for each group),
Machine connection: one pull per specification. The commercial concrete is not larger than the group test block (B),
Sampling length:, tensile test + (is the diameter of the steel bar)
reference value < (is the diameter of the steel bar)
, bending test, and There should be no less than two sets of components for each component, and the location, strength level, and molding time should be marked on the test block (engraved with nails). (+) + (is the bending center diameter)
Reference value<
, waterproof materials, admixtures: Please call for consultation for specific sample delivery. The weight is not less than,
Cold-rolled ribbed steel bars: each specification is drawn one by one and each batch is bent. If there are any changes, the new version of "Equipment Project Quality Inspection Witness Sampling Manual" (China Construction Industry Press) and related standards, specifications, procedures, etc. shall prevail.
Electroslag pressure welding, lap welding, etc.: Each specification is Quanzhou leather goods and other material testing.
, mortar.
The above requirements are for reference only. The inspection order form indicates the level of discussion (Level I, Level II, Level III) and the type of discussion (upsetting straight thread discussion, rolling straight thread discussion, rib stripping rolling straight thread Discussion, sleeve cold extrusion straight thread discussion, tapered thread connection, etc.)
: >Representative quantity: no more than one discussion is an inspection batch.
