Witness the registration conditions of sampler?

(1) What are the requirements for the number of witness sampling inspectors and witness items in the construction project?

You are very serious, saying that a witness can witness several projects at the same time at most; Or a witness can witness tens of thousands of square meters at the same time in the construction project. There is no clear stipulation in laws and regulations, so it is good to have someone to witness it.

(2) How to handle the card of sampler?

The building sampling rate is certified by the labor department.

Witnesses must be qualified:

1 The witness shall be the permanent representative of the construction unit or the supervisor of the supervision unit.

Must have a junior technical title or high school education, with basic knowledge of housing construction.

3. After passing the training and examination, I obtained a witness certificate.

Sampling site witness and monitoring

When sampling, the witness must witness on the spot and have the right to ask the sampling personnel of the construction enterprise to show their "work certificates" according to the specifications. Witnesses must monitor the samples after witnessing the sampling at the site (such as marking the concrete and mortar test blocks after production).

Witnesses must send samples for inspection.

The witness must send the sample to the testing unit together with the sampling personnel of the construction enterprise, and must sign the testing entrustment form and show the witness certificate.

The witness is legally responsible for the sample.

Witnesses shall abide by the relevant provisions of national, provincial and municipal laws and regulations, industrial technical specifications and standards. Witness sampling should adhere to principles, standards and seek truth from facts. Dare to * * * bad phenomenon. Witnesses should be legally responsible for the representativeness and authenticity of the samples they witness!

I hope I can solve your problem.

(4) How to obtain the certificate of supervising witness sampler, training or examination?

After passing the examination, the labor department will issue certificates. The witness must obtain the witness certificate and be authorized by the owner before undertaking the witness work of the authorized project. All building materials entering the construction site must undergo witness sampling and ex-factory test according to the specification requirements, and the test report should be included in the quality assurance data.

The quality of building materials is the basic element of building engineering quality, and the inspection of building materials is an important guarantee for the on-site quality control of building materials. Therefore, witness sampling and inspection are important means to ensure scientific, fair and accurate inspection. However, there are still many problems in witness sampling at present, mainly as follows: some workers' sampling is untrue and irregular;

Some field testers don't know much about construction testing, so they didn't do in-depth and detailed research. Some witnesses "testify" instead of "look" and practise fraud, resulting in the loss of representativeness and authenticity of the samples. Therefore, witness sampling directly affects the quality of building materials.

(4) witness the extended reading of the registration conditions of the sampler.

laboratory report

The inspection unit shall affix the seal of "witness sampling inspection" on the inspection report. If there are unqualified samples, they should be reported to the quality supervision station within 24 hours, and the unqualified project account should be established.

5] Can I take the witness exam if I have a sampler's card?

Cannot be used for multiple working copies at the same time. Now all the projects are put on record, and the witness sampler is one of the people who should put on record. Witnesses need to provide the following materials when filing: 1, witness the sampler's certificate; 2. Witness the seal of the sampler. This material will be filed in the local * * * department.

[6] Can the witness sampler not take the exam without social security?

At present, if you are a company employee and want to take the exam in the name of the company, you need to provide social security certificates. But it depends on what your policy is.

(7) Do you need any graduation certificate for the Shanghai witness sampler exam? Can I take an examination of college students?

There are no special requirements for the academic qualifications of witnesses and sampling personnel.

Shanghai's requirement for witness sampling personnel is that they must be trained and certified after passing the examination.

The relevant matters of the training examination are as follows:

Can you witness sampling without a witness sampler's card?

Examination, rest department certification. The witness must obtain a witness certificate, and the witness occupation of the authorized project can only be undertaken after being authorized by the owner. All building materials entering the construction site must undergo witness sampling and inspection experiments according to the standard threshold, and the experimental reports are listed as quality assurance materials.

The quality of building materials is the fundamental element of building engineering quality, and the inspection of building materials is an important guarantee for the quality control of building materials. Therefore, witness sampling and inspection is an important skill to ensure superstition, fairness and accuracy. However, there are still many achievements in witness sampling at present, which are as follows: some professionals sampling is untrue and irregular;

Some field experimenters don't know much about the construction experiment, so there is no in-depth and detailed discussion. Some witnesses "testify" rather than "see", so they are mystifying, making the sample representative and authentic. Therefore, the development of witness sampling has a direct impact on the quality of building materials.

Levies: Is there a difference between a witness of a construction project and a sampler?

There are differences, the differences are as follows:

1. The sampler belongs to the construction unit and is responsible for accompanying sampling (on-site sampling is taken by workers). The witness is from the supervision unit, just watch the sampler take it (how to ask the sampler to take it).

2. Witnesses and sampling personnel shall be responsible for the representativeness and authenticity of the samples.

3. If the witness sampler causes engineering quality problems due to his own fault, the witness shall be investigated for fault liability. If it is deliberately concealing the quality problems of the project and causing problems, it is even more necessary to investigate the responsibility. If the intentional concealment is based on the instigation of a third person or unit, then the third person and unit shall bear joint and several liability.

4. The witness must obtain the witness certificate and be authorized by the owner. After authorization, the witness can only undertake the witness work of the authorized project. All building materials entering the construction site must undergo witness sampling and ex-factory test according to the specification requirements, and the test report should be included in the quality assurance data.

(9) witness the extended reading of the registration conditions of the sampler:

Witness: ① Witness material sampling and specimen making; ② Labeling the specimen or its packaging; (3) Fill in the witness record account.

Witness requirements: 1. Witness laboratories must be certified by the provincial (or above) Technical Supervision Bureau for Metrology (CMA) and Quality (CMC), and have a laboratory with Grade B (including Grade B) or above testing qualification certificate issued by the provincial (or above) quality supervision department.

2. The witness must hold the test qualification certificate, and the witness is responsible for the representativeness and authenticity of the witness sample.

3. Samples or their packages shall be marked and sealed. The mark and seal shall indicate the sample name, sample quantity, project name, sampling location and sampling date, and shall be signed by the sampler and witnesses.
